    - Wind chills in the single digits Sunday morning for much of E
    OK and NW AR. Temperatures warm into the 40s and lower 50s this
    afternoon.

    - Another cold front arrives this evening and tonight, bringing
    colder conditions for Monday.

    - Low rain chances arrive to SE OK and W-Central AR Wednesday. A
    pattern change may bring more active weather beginning next
    weekend.

    Issued at 1035 PM CST Sat Jan 17 2026

    High pressure continues to pass through the region overnight with
    decreasing winds and mostly clear skies. This will favor
    effective radiational cooling areawide, with lows in the teens
    and single digits in the typically colder valleys/ cold drainage
    spots. High pressure exits to the south and east early Sunday
    morning. This will foster the development of increasing
    southwesterly winds, likely before sunrise in NE OK. This may help
    to increase ambient temperatures slightly, though resultant wind
    chills in the single digits (near 0 in NE OK and NW AR) will make
    for a cold morning either way. Despite the very cold start to the
    day, temperatures will warm nicely back into the 40s and 50s
    under mostly sunny skies. A sfc trough passes through the area
    during the afternoon, shifting winds out of the west-northwest but
    with little sensible change in the airmass. A proper cold front
    arrives Sunday evening and overnight, bringing much colder
    temperatures back to the forecast on Monday.

    (Sunday Night through Saturday)
    Issued at 1035 PM CST Sat Jan 17 2026

    A north-south gradient in high temperatures is expected for
    Monday, with highs struggling to climb out of the 20s in the
    north, and highs in the lower 40s near the Red River. Dry
    conditions are likely to persist, though some very light snow
    showers cannot be ruled out across parts of NE OK and NW AR as a
    subtle wave passes overhead. With dry low level air in place,
    chances are generally too low to mention in the forecast at this
    time. Another chilly night is in store Monday night as high
    pressure fills in with lows in the teens.

    High pressure slides southeast of the area by Tuesday morning
    with intensifying lee troughing ahead of the next storm system.
    This results in breezy SW winds and warmer temperatures during the
    day Tuesday. This pattern will also pull modified gulf air
    northward into the southern plains Tuesday night into Wednesday.
    Meanwhile, a potent shortwave moving through the midwest will
    force a cold front south. Latest guidance develops precipitation
    ahead of the front Wednesday morning and afternoon across SE OK
    and W AR, before being shunted to the south and east as the cold
    front passes through. Rainfall is currently expected to remain
    light, with most totals remaining less than a tenth of an inch.
    High pressure follows for Thursday, promoting quiet conditions.
    Guidance continues to suggest a pattern change by late week, with
    W CONUS ridging breaking down and flow becoming more zonal to
    southwesterly. Model solutions diverge greatly starting next
    weekend, but a window of more active weather and colder
    temperatures appears plausible to finish off the month. The first
    such opportunity may arrive Friday- Saturday. Of course, trends
    will continue to be closely monitored over the coming days.

    switch to the NW late. Another front pushes in late tonight, with
    winds shifting to N.

    After a cold start this morning with many locations in the single
    digits to low teens, southwesterly winds and plenty of sunshine
    will allow temperatures to rebound into the 40s to lower 50s by
    this afternoon. Winds will become more gusty during the afternoon
    hours, still making it feel rather chilly out there for most of
    the day. Another cold front arrives this evening, bringing a
    return to northerly winds and temperatures falling back into the
    teens to lower 20s overnight tonight, while wind chill values drop
    back into the single digits across the northern part of the
    forecast area. The frontal passage will remain dry through
    tonight.

    (Tomorrow through Sunday)
    Issued at 1100 AM CST Sun Jan 18 2026

    Another cold and blustery day is in store for Monday following the
    passage of the cold front. Temperatures will struggle to get above
    freezing during the day Monday thanks to increasing cloud cover
    and continued cold air advection associated with breezy northerly
    winds. More sunshine across the south should allow temperatures to
    rise into the lower 40s. Wind chill values will generally range
    form the teens to low 20s(north) to mid 30s(south). A lobe of mid
    level vorticity will track around the western periphery of the
    large scale trough and track through northern and eastern Oklahoma
    through the day Monday. This will lead to the increasing cloud
    cover over the region, along with a chance at seeing some flurries
    through the afternoon hours, generally north of I-40. Low level
    dry air will likely limit how much reaches the ground, and thus no
    accumulation is expected.

    Another cold night is on tap under surface high pressure Monday
    night before a warming trend kicks in Tuesday into Wednesday as
    southerly winds return. A return to near or above normal temps is
    in the forecast through mid week before another front arrives on
    Wednesday. By this time, a plume of tropical moisture is expected
    to lift north into parts of southeast Oklahoma into western
    Arkansas. Therefore, more widespread coverage of showers is
    progged to develop along and ahead of the frontal boundary during
    the day Wednesday, mainly across far southeast Oklahoma, possibly
    into west central Arkansas. Amounts still seem fairly light, with
    generally less than a quarter inch forecast through Wednesday
    evening. Temperatures don't appear to be quite as cold with this
    front as the bulk of the cold air stays bottled up to the north
    and east of the local region.

    Signs continue to point to a bit of a pattern change heading into
    next weekend, though significant differences and model changes are
    still prevalent at this range. The upper level flow looks to
    become less amplified as the western ridge breaks down and more
    zonal flow aloft develops. This combined with a continued push of
    cold fronts through the area could lead to some chances for wintry precipitation sometime next weekend. Timing of various systems
    along with the strength and location of the push of Arctic air
    remains in limbo. We will continue to keep an eye on the details
    as these differences come into more agreement. Nevertheless, next
    weekend bares watching for potential winter impacts and possibly
    a more significant cold snap than has been the case for the last
    couple of weeks.

    VFR conditions are expected to prevail, with existing mid cloud in

    in mid/high cloud overnight into tomorrow morning areawide. A few
    hour period of gusty west to southwest winds will exist this
    afternoon at all sites, dropping off this evening. Winds will
    increase in speed and shift to a northerly direction in the predawn
    hours tomorrow morning behind the cold front. Will not include any
    gusts at this time, but some chance for isolated gusts up to
    20 kts exists mainly during the latter couple of hours of the

    not overly strong, breezy north winds will hold wind chills in the
    teens this morning, locally in the single digits across far NE OK

    A subtle wave will pass overhead during the morning and afternoon

    Tuesday as pressure gradients tighten ahead of the next storm
    system.

    The southerly flow will eventually transport moisture northward

    There is increasing consensus in a pattern change as we move into

    We'll see increasing mid cloud today, with cigs around 10kft
    through the day. Some snow flurries may fall at times but should
    not be impactful. Gusty north winds behind a cold front across E

    ANother cold day with well below normal temps and wind chills in
    the teens to 20s is unfolding across the region, especially north
    of I-40. A weak mid level disturbance will continue to stream mid
    level cloud cover over the northern half of the forecast area
    through the daytime hours. This along with persistent cold air
    advection from northerly winds will keep temperatures largely
    steady for locations near and north of I-40 this afternoon. Highs
    will struggle to rise above freezing in these locations. Along
    with the clouds, isolated snow flurries could also be seen
    through the afternoon across the north, but a very dry sub cloud
    layer will likely evaporate most precipitation before reaching the
    surface. Therefore, no accumulation or impacts are expected. More
    sunshine across the south will allow temperatures to rise into the
    40s. Winds gradually die off later this afternoon and evening,
    giving way to another cold night with lows in the teens to lower
    20s.

    The surface high shifts southeast Tuesday morning and a couple of
    fairly nice days are in store through the middle part of the week.
    Widespread sunshine and southerly winds return to the Southern
    Plains on Tuesday. The response will be warming temperatures back
    to near or above normal both Tuesday and Wednesday ahead of the
    next system. The next cold front will move through the area during
    the day Wednesday and interact with a plume of tropical moisture
    streaming northward across southeast Oklahoma and western
    Arkansas. This should produce enough moisture ahead of the
    boundary to generate some shower activity Wednesday across
    southeast Oklahoma and west central Arkansas. Any amounts look to
    remain light, generally less than a quarter of an inch in most
    locations. Thursday should be another nice day with temperatures
    near normal and dry weather expected.

    Big changes are in store for Friday into the weekend as we keep
    our eye on the potential for winter weather impacts and bitterly
    cold temperatures across the region. A strong cold front is
    progged to move through the area on Friday, bringing rapidly falling temperatures and strong northerly winds to the area. At the same
    time a cut off mid level low is forecast to move into the
    southwest CONUS with a switch to more westerly or southwesterly
    flow aloft developing over the Southern Plains. This will allow
    more mid level moisture to stream atop the Arctic air mass, and
    with enough lift widespread winter precipitation can be expected
    beginning during the day Friday and lasting into Saturday. Many
    uncertainties still exist, with the main one being how well the
    cut off low will be absorbed into the upper level flow and its
    track across the region. If the low can get fully absorbed and
    track through the Southern Plains into Saturday, this would force
    greater ascent over the region and allow for some heavier bands of precipitation to occur. While the alternative is the low stays
    relatively cut off and weaker forcing over the area only allows
    for lighter precipitation and less in the way of snow amounts over
    much of Oklahoma. The evolution of this low will be the main
    player in the forecast over the coming days as more details
    emerge. Nevertheless, expect at least bitterly cold temperatures
    for a few days with wind chill values likely below zero at times
    and widespread single digit temperatures. Greater icing potential
    appears to stay confined to southeast Oklahoma where the deeper
    cold air will be slower to arrive, but as always, things can shift
    as it gets closer.

    Western CONUS ridging looks to build in again toward the beginning
    of next week, letting temperatures recover somewhat, though any
    snowpack could limit the warmup where greater snowfall can occur.

    impacts is near zero given current observations. A downward trend in
    northerly wind speeds and gusts is also expected from north to south

    A weak cold front will move across the area late Tuesday night and
    Wednesday. Increasing moisture ahead of this front will result in
    scattered showers developing from southeast Oklahoma into
    northwest Arkansas. Precipitation looks to remain all liquid as
    temperatures likely hold steady or slowly rise after a quick drop
    off Tuesday evening. Rainfall amounts through Wednesday morning
    will remain light, generally under one quarter inch.

    All attention remains focused on the winter storm system that will
    likely affect the area Friday and Saturday. Bitterly cold air will
    move south into the area late Thursday night and Friday morning,
    setting the stage for widespread wintry precipitation. While some
    light precipitation may fall during the day Friday, the more
    significant precipitation looks to hold off until Friday night and
    Saturday. At this time, it appears much of the area will see
    mostly snow, although some wintry mix will be possible initially
    south of Interstate 40 before a changeover to snow occurs. Across
    far southeast Oklahoma, a more prolonged period of freezing rain
    and/or sleet will be possible, with a full changeover to snow
    perhaps not occurring until during the day Saturday. Temperatures
    will be bitterly cold, with many places remaining in the teens
    during the day Saturday.

    While it remains too early to focus on specific amounts of ice and
    snow, the consensus is for the greatest QPF to fall across the
    southern half of the forecast area, with lesser amounts to the
    north. Lesser may be relative in this case, as a significant
    number of models and ensembles show QPF values over one half inch
    across the entire forecast area, and snow ratios will be higher
    than the usual 10:1. There is a subset of models though that show
    much lower amounts in the northern part of the forecast area. For
    now, stayed fairly conservative with snow amounts since we are
    still 4+ days out. Amounts will be refined in the coming days as
    confidence increases.

    Skies will clear Sunday into early next week, with temperatures
    highly uncertain as they will be fully dependent on the amount of

    A weak cold front will move into the region late tonight into
    Wednesday morning. A plume of tropical moisture will also advance
    north overnight tonight across southeastern Oklahoma and western
    Arkansas ahead of the frontal boundary. This should result in
    scattered shower activity developing ahead of the front from early
    Wednesday morning through the early afternoon hours. Amounts
    generally remain light at less than a quarter of an inch before
    precipitation wraps up from northwest to southeast with the push
    of drier air into the area behind the front. Temperatures behind
    the front won't be overly cold, topping out near normal again on
    Wednesday across much of the area. Another nice day is in store
    on Thursday ahead of big changes coming for the last part of the
    week into the weekend.

    The main weather impact for this forecast period begins on Friday
    as a strong Arctic front moves through the area Friday morning.
    Bitterly cold air will spill south through the day Friday, along
    with gusty northerly winds dropping wind chill values into the
    single digits by Friday afternoon. Along with the cold
    temperatures a storm system is progged to take shape to the west
    and force precipitation overtop the cold airmass, with a prolonged
    period of winter precip appearing more likely across a portion of
    the forecast area through the weekend. The main feature that will
    play a role in snow/ice amounts is the evolution of a subtropical
    cutoff low that will be off the Southern California Coast at mid
    week. How this feature phases with a polar jet shortwave trough
    dropping south along the western edge of the parent eastern CONUS
    trough will ultimately determine where and when the heaviest
    precipitation occurs. This low will pump a continuous flow of
    Pacific moisture over much of the Southern Plains from Friday
    through Sunday. Model trends have been a little further south
    with the subtropical jet and thus heavier snow and ice amounts
    have shifted southward as well.

    Precipitation is progged to start during the day Friday as the
    mid level warm advection region intensifies over the Southern
    Plains. Initial precip will likely be rain along the Red River to
    a winter mix of snow, sleet, freezing rain further north into the
    Arctic air. A transition to mostly all snow across the forecast
    area, with the possible exception of far southeast Oklahoma, is
    likely by Friday evening as the deeper cold air continues to
    spill south. The system will be slow moving, so winter precip
    could last from 36 to 48 hours in some locations with the higher
    likelihood being south of I-40 at this time. Still, the prolonged
    period of even lighter snow will add up throughout all of eastern
    Oklahoma and western Arkansas by the time the storm ends on
    Sunday. The potential for the heaviest snowfall is located
    generally south of I-40 currently, where some heavier banding
    could occur closer to the stronger lift associated with the
    subtropical wave. We are looking at mostly snow impacts for the
    region, though some icing and sleet potential at the onset of
    precipitation could result in some ice impacts across the south
    prior to snow arrival. Amounts will fluctuate in the coming days
    as trends in the data get a better handle on the track of the
    prevailing features.

    Along with the precip, bitter cold temperatures will last for
    several days through the weekend, with temperatures in the teens
    and single digits from Friday evening, lasting into the day
    Monday. Upper ridging looks to return to the area beginning next
    week allowing for temperatures to warm, though any snowpack will
    likely limit the warmup potential as it melts.

    After another relatively mild day Thursday, big changes are on the
    way beginning late Thursday night. An arctic cold front will move
    south across the area late Thursday night and Friday morning, with
    strong and gusty north winds and falling temperatures in its wake.
    Temperatures during the day Friday will fall through the teens and
    20s, with some light precipitation developing as well, especially
    across southeast Oklahoma where a wintry mix will be possible.
    Light snow will be possible by Friday afternoon farther north, but
    a dry low level airmass will likely result in little or no snow
    accumulation during the day Friday.

    Conditions will deteriorate Friday evening and overnight, with
    wintry precipitation becoming more widespread and heavier with
    time. Mainly snow is expected north of Interstate 40, with only a
    slight chance of sleet mixed in, with greater potential for a
    wintry mix south of Interstate 40. The best chance for a glaze of
    ice will be across far southeast Oklahoma, with sleet more likely
    between Interstate 40 and the far southeast part of the state.
    Several inches of snow accumulation will be likely in some places
    before daybreak Saturday.

    This initial round of precipitation will continue into Saturday
    morning, with the transition to all snow sagging slowly south with
    time. A break in the intensity of the precipitation looks likely
    late Saturday morning and afternoon before the main upper level
    system approaches by Saturday evening increasing precipitation
    intensities once again. By this time, snow should be the main
    precipitation type in all locations. This second wave of heavier
    snow will bring at least several inches of snow to most all areas
    before it tapers off and ends early Sunday.

    Total snow and sleet accumulations of 6 to 10 inches will be
    common, with locally higher amounts. Some places will likely
    receive over a foot of snow, and cannot rule out at least isolated
    totals over 15 inches, mainly between Interstates 44 and 40.

    Skies will clear later Sunday, with cold temperatures persisting
    well into next week as the snow slowly begins to melt. Overnight
    low temperatures may dip well below zero in a few spots Sunday
    night assuming skies are clear and winds are calm, and later
    forecasts may need to trend overnight lows colder.

    morning, with the transition to all snow sagging slowly south with
    time. A break in the intensity of the precipitation looks likely
    late Saturday morning and afternoon before the main upper level
    system approaches by Saturday evening increasing precipitation
    intensities once again. By this time, snow should be the main
    precipitation type in all locations. This second wave of heavier
    snow will bring at least several inches of snow to most all areas
    before it tapers off and ends early Sunday.

    Total snow and sleet accumulations of 6 to 10 inches will be
    common, with locally higher amounts. Some places will likely
    receive over a foot of snow, and cannot rule out at least isolated
    totals over 15 inches, mainly between Interstates 44 and 40.

    Skies will clear later Sunday, with cold temperatures persisting
    well into next week as the snow slowly begins to melt. Overnight
    low temperatures may dip well below zero in a few spots Sunday
    night assuming skies are clear and winds are calm, and later
    forecasts may need to trend overnight lows colder.

    Mostly clear skies will continue through the afternoon and overnight
    hours with this mornings cold front quickly moving east. Mild
    temperatures are expected this afternoon with highs in the 50s, but
    will cool to a little below normal tonight, mainly in the 20s.

    (Tomorrow through Wednesday)

    Thursday will be another quiet day with highs in the 50s and
    increasing clouds ahead of the next storm system. Attention then
    turns to the major to potentially historic winter storm expected to
    clobber the region Friday into Sunday. The large scale setup will
    feature a near record breaking arctic high descending south this
    weekend, with surface pressure as high as 1052 hPa. This very cold
    and very dense airmass will sweep south through the Plains.
    Meanwhile, a well positioned cut off low near southern California
    will be in just the right spot to be incompletely absorbed into
    the arctic trough. This will maximize the time the region will
    spend under moist isentropic upglide as well as upper level lift
    from the jet. The result will be a prolonged period of moderate to
    heavy precipitation resulting in significant snow and ice.
    Details on the timing and amounts are found below.

    The initial arctic intrusion will slosh in rather than surge. A
    light northerly pressure gradient will gradually increase north
    winds early Friday morning, becoming stronger during the daytime
    with gusts to 25-35 mph. Temperatures will fall below freezing near
    and north of the I-44 corridor by daybreak, with subfreezing air
    working south to roughly a line from McAlester to Fayetteville by
    early afternoon. Some model guidance produces some light frontal
    precip during this timeframe. This would be rain for southeast OK
    to the south of the previously mentioned demarcation line. North
    of there, it could be a mixture of light snow, sleet, or freezing
    rain. Amounts would be minimal, but some minor impacts can't be
    ruled out by late morning north of I-40 and early afternoon south
    of I-40. Still, the most likely scenario is for impacts to begin
    during the afternoon to early evening hours. It is also worth
    mentioning that if model guidance is incorrect there could be
    shifts in the precipitation types. That applies to the entire
    storm system.

    By Friday evening cold air will surge south more quickly, with the
    entire forecast area now below freezing. The coldest air will be
    in northeast OK where temps will be in the teens by this point.
    Upper level lift will increase with strong moist advection
    occurring. This will result in moderate to heavy precipitation
    spreading northward with time. Careful examination of model
    soundings suggests all or mostly all snow north of roughly I-40,
    with heavy sleet for areas to the south (including the Fort Smith
    area). It would only be for portions of far southeast OK where
    appreciable freezing rain may occur. Snow in the north and sleet
    or freezing rain in the south will continue all night. For areas
    seeing snow, winds gusting to 20-30 mph will result in blowing and
    drifting snow. For areas seeing freezing rain, this combination
    could result in power outages.

    Temperatures will remain steady or slowly cool during the day
    Saturday. High temperatures will be 9-17F for northeast OK and
    northwest AR, with 18-28F for southeast OK and west-central AR.
    The same layout of precipitation types will largely persist
    through much of the day. But as the coldest air sinks into the
    region Saturday evening, all areas should at least briefly change
    over to snow. There was a definite trend on 12z guidance today
    for a bit of a lull midday Saturday before an additional surge of
    precipitation occurs into Sunday morning. Higher snow ratios at
    this point would likely result in efficient accumulation. Storm
    total amounts are still uncertain, but confidence is high they
    will be significant. Much of northeast OK and northwest AR is
    expected to see 8-12 inches. Even the "fizzle" scenario of 4-6
    inches would still easily warrant a Winter Storm Warning. Sleet
    accumulations could easily be a couple of inches for southeast OK
    into west-central AR. Precipitation type is most uncertain near
    the Red River. Depending on the exact precipitation type it could
    be more sleet or more freezing rain, but either way, significant
    ice is expected and it will greatly impact travel. These types of
    storm totals will likely greatly impact area infrastructure for a
    time, with difficult to impossible travel. Power outages are
    certainly possible, but more especially within areas of freezing
    rain. This is a storm to take seriously and prepare now.

    We have spoken extensively of the precipitation issues, but extreme
    cold is also expected. Wind chills will be below zero for a good
    chunk of the area by Saturday afternoon, with values as low as -10F
    or so (and 0 to 10F in southeast OK). These values will likely fall
    below zero areawide on Sunday morning, with wind chill readings as
    low as -15F in the north. Clear skies and light winds into Monday
    morning may produce actual lows below zero. This type of setup
    historically has resulted in lows even below -10F, and some mode
    guidance hints at that for colder areas north of I-40. For now went
    with -7F to +2F Monday morning. Accordingly, an Extreme Cold Watch
    was issued for early Saturday into Monday morning. Several record
    lows or min maximums (lowest high) are possible based on the current
    forecast.

    Temperatures will begin to warm Monday and Tuesday with light
    southerly flow, and temperatures may break freezing Tuesday.
    However, a secondary dry cold front will drop another cold airmass
    into the area midweek. This combined with likely deep snow/ice cover
    will probably keep roads a mess through much of the week. Be
    prepared for a long period with limited mobility and potentially
    limited power as well.

    (Thursday Night through Wednesday)
    Issued at 1110 PM CST Wed Jan 21 2026

    Forecast remains on track for a robust and high-impact winter
    storm to affect eastern OK and western AR beginning late Thursday
    night through Sunday afternoon. It is worth noting that this
    forecast will likely continue to be adjusted over the next couple
    of days as newer model data comes in. Precipitation totals and
    timing will change.

    A strong Arctic cold front will move across the region late
    Thursday night into Friday morning. Temperatures are forecast to
    steadily fall through the daytime Friday, with temperatures
    falling below freezing before noon for most areas north of I-40
    and elsewhere by sunset. Winds behind the front will remain gusty
    through the daytime Friday, with gusts up to 35 mph. In turn, this
    will make temperatures feel even colder as wind chill values
    hover in the single digits and teens going into Friday night. The
    frontal boundary will initially bring in some very dry air near
    the surface. Models and ensembles still clash with regards to
    precipitation onset timing, partly due to the dry, sub-cloud
    layer. With that said, there may be a few locations, especially
    south of I-40, where full saturation to the surface occurs Friday morning/afternoon and light precipitation (with minor
    accumulations of rain, freezing rain, and sleet) is possible.

    There is much better agreement in models that indicate a couple
    of upper-level waves of heavier and more impactful precipitation,
    with the first wave arriving late Friday afternoon and into the
    evening as low-level moisture surges into the area ahead of an
    approaching shortwave trough moving onshore from Baja California.
    Though there are still some differences in model data, this first
    wave should linger through late morning Saturday before exiting to
    the east. A lull in heavy precipitation is expected thereafter,
    with spotty and periodic light precipitation falling through the
    afternoon Saturday. A second upper-level wave is anticipated to
    impact and bring additional widespread heavy wintry precipitation
    beginning Saturday evening and will continue through much of the
    daytime Sunday before the entire storm system exits to the east.

    Confidence is medium-high that precipitation north of I-40 will
    fall mainly as snow through the entire event from start to finish.
    However, forecast soundings from a few of the latest
    deterministic forecast models show a warm nose in place between
    I-40 and Highway 412, leaving a low chance of sleet mixing in with
    snow as far north as Highway 412 through the daytime Saturday.
    Snowfall totals, which do include sleet amounts, likely will not
    be impacted too much as the more dominate precipitation type
    should be snow north of I-40. Still, half an inch of sleet will
    still be possible. Precipitation types along and south of I-40
    will be a lot more messy, with a more pronounced warm nose in
    place most of this event. Freezing rain, sleet, and snow will all
    be probable at some point, especially across far southeast OK and closer
    to the Red River. As far as total snow/sleet/ice amounts, current
    thinking remains mostly the same as the previous forecast. In
    general, 8 to 12 inches of snow (with some sleet mixed in),
    locally higher, is still expected north of I-40 through Sunday
    afternoon. South of I-40, a mixture of sleet and snow is expected
    to total between 4 to 6 inches. Additionally, ice amounts near the
    Red River have increased some, with totals to near half an inch
    in Choctaw and Pushmataha counties possible. However, there is
    very low confidence on the ice amounts at this time. It is
    possible that much of this could fall as sleet instead of ice. The
    Winter Storm Watch that is currently in effect for all of the CWA
    will likely be upgraded to a warning tomorrow morning.

    Temperatures will be extremely and dangerously cold Friday
    through the beginning part of next week, given snowfall amounts
    and accumulations. An Extreme Cold Watch remains in effect from
    midnight Saturday until noon Sunday. Daytime highs will be in the
    single digits and teens Saturday and Sunday. The coldest period of
    the long-term will be Sunday night into Monday morning when clouds
    begin to clear and winds begin to die down. A deep snowpack will
    essentially keep temperature well below than what forecast models
    are suggesting. A gradual warm-up will occur Monday into Tuesday
    when southerly winds return, with mostly dry weather into midweek.

    tonight and Thursday across the CWA. By Thursday evening, scattered
    mid clouds are forecast to begin lifting into eastern Oklahoma and
    west central Arkansas ahead of the approaching Arctic airmass. Winds
    through the period start out variable and become more east/southeast
    during the day Thursday. Late in the period, winds start to return
    more north/northeast for parts of northeast Oklahoma. VFR conditions
    should persist through the TAF period.

    Tranquil weather will proceed overnight tonight and through the
    daytime Thursday, with no impacts due to weather expected. High
    clouds will begin to increase after midnight tonight, becoming
    broken or overcast by daybreak Thursday. Winds will remain
    generally light through the period despite a very weak frontal
    boundary moving into northeast OK and far northwest AR after
    midnight tonight. The front will not amount to much of anything
    and will wash-out by mid-morning. Winds will eventually veer from
    the northeast to the east or east-southeast around midday midday
    as surface high pressure shifts east of the area and becomes
    elongated. As for temperatures...Thursday will be the warmest day
    for at least a full week, perhaps longer, with afternoon high
    temperatures reaching the low-mid 50s. Be sure to enjoy the warmth
    outside while it lasts.

    (Thursday Night through Wednesday)
    Issued at 1110 PM CST Wed Jan 21 2026

    Forecast remains on track for a robust and high-impact winter
    storm to affect eastern OK and western AR beginning late Thursday
    night through Sunday afternoon. It is worth noting that this
    forecast will likely continue to be adjusted over the next couple
    of days as newer model data comes in. Precipitation totals and
    timing will change.

    A strong Arctic cold front will move across the region late
    Thursday night into Friday morning. Temperatures are forecast to
    steadily fall through the daytime Friday, with temperatures
    falling below freezing before noon for most areas north of I-40
    and elsewhere by sunset. Winds behind the front will remain gusty
    through the daytime Friday, with gusts up to 35 mph. In turn, this
    will make temperatures feel even colder as wind chill values
    hover in the single digits and teens going into Friday night. The
    frontal boundary will initially bring in some very dry air near
    the surface. Models and ensembles still clash with regards to
    precipitation onset timing, partly due to the dry, sub-cloud
    layer. With that said, there may be a few locations, especially
    south of I-40, where full saturation to the surface occurs Friday morning/afternoon and light precipitation (with minor
    accumulations of rain, freezing rain, and sleet) is possible.

    There is much better agreement in models that indicate a couple
    of upper-level waves of heavier and more impactful precipitation,
    with the first wave arriving late Friday afternoon and into the
    evening as low-level moisture surges into the area ahead of an
    approaching shortwave trough moving onshore from Baja California.
    Though there are still some differences in model data, this first
    wave should linger through late morning Saturday before exiting to
    the east. A lull in heavy precipitation is expected thereafter,
    with spotty and periodic light precipitation falling through the
    afternoon Saturday. A second upper-level wave is anticipated to
    impact and bring additional widespread heavy wintry precipitation
    beginning Saturday evening and will continue through much of the
    daytime Sunday before the entire storm system exits to the east.

    Confidence is medium-high that precipitation north of I-40 will
    fall mainly as snow through the entire event from start to finish.
    However, forecast soundings from a few of the latest
    deterministic forecast models show a warm nose in place between
    I-40 and Highway 412, leaving a low chance of sleet mixing in with
    snow as far north as Highway 412 through the daytime Saturday.
    Snowfall totals, which do include sleet amounts, likely will not
    be impacted too much as the more dominate precipitation type
    should be snow north of I-40. Still, half an inch of sleet will
    still be possible. Precipitation types along and south of I-40
    will be a lot more messy, with a more pronounced warm nose in
    place most of this event. Freezing rain, sleet, and snow will all
    be probable at some point, especially across far southeast OK and closer
    to the Red River. As far as total snow/sleet/ice amounts, current
    thinking remains mostly the same as the previous forecast. In
    general, 8 to 12 inches of snow (with some sleet mixed in),
    locally higher, is still expected north of I-40 through Sunday
    afternoon. South of I-40, a mixture of sleet and snow is expected
    to total between 4 to 6 inches. Additionally, ice amounts near the
    Red River have increased some, with totals to near half an inch
    in Choctaw and Pushmataha counties possible. However, there is
    very low confidence on the ice amounts at this time. It is
    possible that much of this could fall as sleet instead of ice. The
    Winter Storm Watch that is currently in effect for all of the CWA
    will likely be upgraded to a warning tomorrow morning.

    Temperatures will be extremely and dangerously cold Friday
    through the beginning part of next week, given snowfall amounts
    and accumulations. An Extreme Cold Watch remains in effect from
    midnight Saturday until noon Sunday. Daytime highs will be in the
    single digits and teens Saturday and Sunday. The coldest period of
    the long-term will be Sunday night into Monday morning when clouds
    begin to clear and winds begin to die down. A deep snowpack will
    essentially keep temperature well below than what forecast models
    are suggesting. A gradual warm-up will occur Monday into Tuesday
    when southerly winds return, with mostly dry weather into midweek.

    Mild conditions are expected today with high temperatures in the

    advance of the next storm system. The leading edge of the arctic
    airmass will move through this evening, with northerly flow
    beginning in northeast OK. North winds will then gradually spread
    south and strengthen during the overnight hours. Cold air will
    initially be sluggish in its southward push, with subfreezing air
    roughly making it to a line from Henryetta up through Fayetteville
    by daybreak. Temperatures will range from the mid 20s near the KS
    border to low 40s near the TX border at daybreak.

    .LONG TERM...
    (Tomorrow through Thursday)

    Cold air will increasing push into the area Friday, especially near
    and north of Highway 412, with gusts of 25-35 mph. Further south, it
    is unclear what kind of progress the cold air will make during the
    day. The AIFS and NAM models are typically more reliable with cold
    air, and they suggest temperatures remaining just above freezing to
    the south of I-40 until the afternoon hours, with temperatures then
    going below freezing areawide. We are within the window of CAM
    guidance at this point. Much of which shows some light rain showers
    in southeast OK from roughly noon to 3 PM. Any storm preparations or
    travel should be completed by midday Friday across the area. For the
    later afternoon hours, precipitation will increase across southeast
    OK, with rain transitioning to either freezing rain or sleet,
    depending on the exact cold air progression. Any wet roads will
    freeze during this period. Precipitation will spread north to the
    remainder of the forecast area during the evening hours.
    Precipitation type will be mostly snow north of I-40, with mostly
    sleet to the south. There will be variation in this generalization
    in both time and location. Some freezing rain near the Red River may
    occur, but is generally expected to remain below 0.2 inches. But
    again, this depends on how quickly the cold air surges south.

    Moderate to heavy precipitation will then continue overnight into
    Saturday morning as moist isentropic upglide intersects lift from an
    upper level jet. Exact totals remain uncertain given questions of
    how far north sleet occurs, exact heavier precipitation axis, and so
    on. But total snow will be multiple inches for most areas in the
    north, with an inch or two of sleet in the south. There is
    uncertainty during the day Saturday, but the majority of guidance
    leans towards either a break or at least weaker precipitation rates
    for a time. Given gusty northerly winds of 20-25 mph, some blowing
    and drifting of snow is likely. Temperatures will hover near 8-15 F
    in the north during the daytime, and 15-25 F in the south.

    The main trough axis will then swing through later Saturday into
    Sunday, reinvigorating precipitation rates. With cooling upper
    levels this will cause snow ratios to increase in the north, and
    nudge the precipitation type towards snow with time in southern
    areas. There is still a decent subset of guidance that keeps this
    second surge weaker and further south, which would limit totals. The
    majority of guidance, however, shows this second band as robust with
    low density snow, meaning it will accumulate efficiently. Snow may
    linger as long as early Sunday afternoon before totally shutting
    off.

    These factors together point to a widespread storm total of 6-12
    inches of snow north of I-40. If some of the higher end guidance
    were to develop (less likely) it is possible local accumulations
    could be as high as 18-20 inches somewhere. Conversely, the low end
    scenario (also less likely) would be 6-8 inches in the north.
    Blowing and drifting of snow will make travel very difficult if not
    outright impossible for a time. South of I-40, sleet accumulations
    will be prolific, potentially up to 3-4 inches in spots. These types
    of totals will cripple many area roads. Typically sleet takes a long
    time to melt so impacts will linger for multiple days. A couple of
    inches of snow may fall on top of the sleet near the end of the
    storm. Additionally, some icing near the Red River could result in
    localized power outages. A Winter Storm Warning is in effect to
    cover these expected storm totals.

    Very low wind chills will develop Friday evening in the north,
    spreading to all areas Saturday. Wind chills will fall below zero
    for at least a time in most locations. Actual high temperatures
    Saturday and Sunday will mainly be in the teens. Lows are expected
    to be well below zero Monday morning for many areas. The Extreme
    Cold Watch was upgraded to a Warning to account for this danger.

    Temperatures will slowly moderate into the middle of next week, with
    highs climbing into the 30s but lows remaining below 20 each night.
    This will refreeze and compact existing snow and sleet, keeping road
    conditions treacherous into at least late week. There is a bit of a
    signal in the ensemble guidance for a weak system near next Friday,
    but no additional precipitation should occur after Sunday until at
    least then.

    Mild conditions are expected today with high temperatures in the
    50s. Cloud cover will increase and lower throughout the day in
    advance of the next storm system. The leading edge of the arctic
    airmass will move through this evening, with northerly flow
    beginning in northeast OK. North winds will then gradually spread
    south and strengthen during the overnight hours. Cold air will
    initially be sluggish in its southward push, with subfreezing air
    roughly making it to a line from Henryetta up through Fayetteville
    by daybreak. Temperatures will range from the mid 20s near the KS
    border to low 40s near the TX border at daybreak.

    (Tomorrow through Thursday)

    Cold air will increasing push into the area Friday, especially near
    and north of Highway 412, with gusts of 25-35 mph. Further south, it
    is unclear what kind of progress the cold air will make during the
    day. The AIFS and NAM models are typically more reliable with cold
    air, and they suggest temperatures remaining just above freezing to
    the south of I-40 until the afternoon hours, with temperatures then
    going below freezing areawide. We are within the window of CAM
    guidance at this point. Much of which shows some light rain showers
    in southeast OK from roughly noon to 3 PM. Any storm preparations or
    travel should be completed by midday Friday across the area. For the
    later afternoon hours, precipitation will increase across southeast
    OK, with rain transitioning to either freezing rain or sleet,
    depending on the exact cold air progression. Any wet roads will
    freeze during this period. Precipitation will spread north to the
    remainder of the forecast area during the evening hours.
    Precipitation type will be mostly snow north of I-40, with mostly
    sleet to the south. There will be variation in this generalization
    in both time and location. Some freezing rain near the Red River may
    occur, but is generally expected to remain below 0.2 inches. But
    again, this depends on how quickly the cold air surges south.

    Moderate to heavy precipitation will then continue overnight into
    Saturday morning as moist isentropic upglide intersects lift from an
    upper level jet. Exact totals remain uncertain given questions of
    how far north sleet occurs, exact heavier precipitation axis, and so
    on. But total snow will be multiple inches for most areas in the
    north, with an inch or two of sleet in the south. There is
    uncertainty during the day Saturday, but the majority of guidance
    leans towards either a break or at least weaker precipitation rates
    for a time. Given gusty northerly winds of 20-25 mph, some blowing
    and drifting of snow is likely. Temperatures will hover near 8-15 F
    in the north during the daytime, and 15-25 F in the south.

    The main trough axis will then swing through later Saturday into
    Sunday, reinvigorating precipitation rates. With cooling upper
    levels this will cause snow ratios to increase in the north, and
    nudge the precipitation type towards snow with time in southern
    areas. There is still a decent subset of guidance that keeps this
    second surge weaker and further south, which would limit totals. The
    majority of guidance, however, shows this second band as robust with
    low density snow, meaning it will accumulate efficiently. Snow may
    linger as long as early Sunday afternoon before totally shutting
    off.

    These factors together point to a widespread storm total of 6-12
    inches of snow north of I-40. If some of the higher end guidance
    were to develop (less likely) it is possible local accumulations
    could be as high as 18-20 inches somewhere. Conversely, the low end
    scenario (also less likely) would be 6-8 inches in the north.
    Blowing and drifting of snow will make travel very difficult if not
    outright impossible for a time. South of I-40, sleet accumulations
    will be prolific, potentially up to 3-4 inches in spots. These types
    of totals will cripple many area roads. Typically sleet takes a long
    time to melt so impacts will linger for multiple days. A couple of
    inches of snow may fall on top of the sleet near the end of the
    storm. Additionally, some icing near the Red River could result in
    localized power outages. A Winter Storm Warning is in effect to
    cover these expected storm totals.

    Very low wind chills will develop Friday evening in the north,
    spreading to all areas Saturday. Wind chills will fall below zero
    for at least a time in most locations. Actual high temperatures
    Saturday and Sunday will mainly be in the teens. Lows are expected
    to be well below zero Monday morning for many areas. The Extreme
    Cold Watch was upgraded to a Warning to account for this danger.

    Temperatures will slowly moderate into the middle of next week, with
    highs climbing into the 30s but lows remaining below 20 each night.
    This will refreeze and compact existing snow and sleet, keeping road
    conditions treacherous into at least late week. There is a bit of a
    signal in the ensemble guidance for a weak system near next Friday,
    but no additional precipitation should occur after Sunday until at
    least then.

    Broken high clouds this evening will give way to mid level clouds
    lifting into the CWA late tonight and Friday. At the same time, an
    Arctic cold front drops into the region tonight and spreads over
    the CWA Friday morning with gusty northeasterly winds.
    Precipitation chances then develop Friday afternoon from southwest
    to northeast and have added Prob30 groups for timing of the onset
    of a wintry mix. VFR conditions are currently forecast, though
    MVFR conditions could develop within the precip across southeast

    Surface analysis from across the country shows the much
    anticipated Arctic cold front draped across northern/central KS as
    of this writing. The front will be moving into northeast OK and
    northwest AR in the next couple of hours. Behind the boundary,
    temperatures will fall steadily through the overnight hours and
    continue to fall through the daytime Friday. Because temperatures
    will not follow the typical diurnal curve, they may need to be
    adjusted overnight tonight and during the daytime Friday.

    From latest model guidance, temperatures should fall below
    freezing north of I-40 by or just after sunrise and by mid-late
    afternoon south. The frontal boundary will initially bring in
    some very dry air near the surface, especially across northeast
    OK. Hi-res models indicate light precipitation developing through
    the morning and even into the afternoon from the approaching storm
    system, mainly across eastern OK. Dewpoint depressions will be
    quite large across northeast OK through the daytime, greater than
    25 degrees in many areas. If precipitation is able to reach the
    ground, it will be light with little to no accumulations expected.
    South of I-40, air near the surface will not be quite as dry.
    Light rain may mix with some sleet during the morning and
    afternoon from McAlester latitude and southward, with best
    chances closer to the Red River. Surface temperatures through much
    of the afternoon should stay above freezing as the precipitation
    falls, and light rain accumulations are possible.

    The frontal boundary will also bring in some gusty northeast
    winds. Gusts up to 35 mph will be probable initially, especially
    across much of northeast OK. Winds are expected to be slightly
    lighter south of I-40. But regardless, these winds will make
    temperatures feel much colder. Daytime highs Friday will occur
    before sunrise, with temperatures falling into the 20s north of
    I-40 by late in the morning. Wind chill values will steadily fall
    from the teens to the single digits, and even below 0 degrees near
    the OK/KS border. Needless to say, it is going to be cold and
    feel colder!

    Overall, no drastic changes were made from the previous forecast.
    Latest suite of forecast models continue to suggest there will be
    two rounds of heavy wintry precipitation between Friday night and
    Sunday afternoon. Consensus in model data show the first wave
    will arrive between sunset and midnight Friday evening/night.
    Despite being less than 24 hours from the onset of the moderate to
    heavy wintry precipitation, there are still many uncertainties on
    how temperatures above the inversion will behave, which will
    ultimately affect precipitation type and amounts. Snow should be
    the predominate precip type north of I-40. However, forecast
    soundings from the NAM and GFS have been consistent in showing a
    pronounced warm nose hovering around the freezing line near the
    700mb layer as far north as Tulsa and Fayetteville overnight
    Friday into Saturday morning. This would suggest a mixture of
    sleet and snow will fall, at least initially, generally between
    I-40 and Highway 412. South of I-40, there is a lot more
    uncertainty. Light to moderate precipitation may already be
    ongoing by the start of the long-term period as strong moisture
    and warm air advection are drawn into the region from the south.
    Precipitation is expected to start off as liquid rain, especially
    closer to the Red River, but there may be enough dry air aloft for
    a production of sleet to mix in with the rain by late afternoon
    or early evening. Once surface temperatures drop below freezing
    after sunset, a mixture of freezing rain and sleet will prevail.
    How much freezing rain will fall is still debatable at this time,
    but the highest chance for ice accumulations up to a couple of
    tenths of an inch will mostly be across Choctaw and Pushmataha
    counties and perhaps southern portions of Pittsburg, Latimer, and
    Le Flore counties.

    Moderate to heavy precipitation from the first wave will continue
    through the overnight hours Friday and will begin to exit to the
    east of the forecast area sometime late morning Saturday. Snowfall
    amounts through noon Saturday vary depending on which model you
    look at, and again, will be mostly confined along and north of
    I-40. Snow amounts between 4 and 8 inches seems reasonable,
    locally higher, for this first round of heavy precipitation.
    Meanwhile, south of I-40, sleet accumulations around 1 to 3 inches
    is not out of question, but will highly depend how much freezing
    rain is able to mix in.

    A lull in heavy precipitation is still expected to occur Saturday
    afternoon and into the evening. Both global and hi-res models
    continue to show a chance of lighter precipitation periodically
    through the afternoon, with maybe additional light snow and sleet accumulations. If drier air aloft is able to infiltrate during
    this lull period, there could be a period of freezing drizzle,
    even north of I-40, before the next heavy round arrives. This will
    have to be monitored closely over the next 24 hours. The second
    round of moderate to heavy precipitation is anticipated to arrive
    mid to late evening Saturday as a Baja Low moves onshore over
    northwest Mexico and merges with the main upper level trough over
    the Great Basin/Dessert Southwest. This second round will persist
    overnight Saturday and through at least mid to late morning
    Sunday, perhaps lingering into the afternoon for portions of
    western AR before shifting east. Additional snowfall amounts
    between 4 and 8 inches can be expected north of I-40 during this
    period, with generally 2 to 4 inches of a mix of sleet and snow
    south.

    Total snowfall amounts from Friday night through Sunday afternoon
    will generally range between 8 and 12 inches near and north of
    I-40. However, guidance, especially hi-res guidance, has been
    persistent in showing periodic high snowfall rates (1 to 2 inches
    an hour) from intense snow bands. Localized snow amounts 15 to 20
    inches cannot be ruled out in a few locations, especially if any
    convective snow bands setup. These amounts do include sleet too,
    but sleet accumulations should stay below an inch at this time.
    South of I-40, sleet amounts are expected to overpower any snow
    accumulations, with up to 4 inches of sleet piling up for a few
    locations. The best chance of snow south of I-40 will actually
    occur Sunday morning, once the 850mb front is able to push south
    across southeast OK. This is where 2 to 3 inches of snow may fall
    on top of any ice and sleet that has fallen. As for ice amounts,
    as mentioned above, the highest probabilities for freezing rain
    will occur in Choctaw and Pushmataha counties, where anywhere from
    a glaze to a few tenths of an inch will be possible, mainly
    falling late Friday night into Saturday morning. This could result
    in localized power outages for this area. This event will have
    very high impacts for everyone, regardless how much snow, sleet,
    or ice falls. And they will fall. Travel will be extremely
    difficult to impossible at times, especially during the heaviest
    precipitation and before things start to melt. Stay home this
    weekend, if possible.

    Temperatures and especially wind chill temperatures will become
    dangerous north of I-40 by Friday night and spreading south of
    I-40 by Saturday morning. Actual high temperatures Saturday and
    Sunday will mainly be in the teens. Meanwhile, overnight lows will
    fall to the single digits Friday night for the majority of the
    area and for all of the area Saturday night. The coldest night is
    expected to be Sunday night into Monday morning after the storm
    system departs, winds calm down, and skies begin to clear. Strong
    radiational cooling will occur at the same time when there is
    potentially several inches of snow/sleet on the ground. Actual
    temperatures will fall well below zero for most locations, save
    near the Red River, Sunday night into Monday morning. Breezy
    northerly winds Friday night through Sunday evening will
    contribute to wind chills below zero or in the single digits for
    much of the forecast area between Saturday morning and Sunday
    night. Please remember to protect vulnerable people, pets, plants,
    and pipes over the next several days. Use space heaters and
    generators properly.

    Temperatures will be slow to rise after Monday. Temps are expected
    to finally rise above freezing (briefly) Tuesday afternoon and
    again Wednesday afternoon. This likely will not be enough to melt
    all of the snow and sleet on the ground and any melting that does
    occur will likely refreeze both Tuesday night and Wednesday night
    when temperatures fall back below freezing. Any existing snow and
    sleet on the ground will compact, keeping road conditions less
    than ideal through the remainder of the workweek. Good news is
    that no additional precipitation is expected beyond Sunday.

    through the afternoon, with maybe additional light snow and sleet accumulations. If drier air aloft is able to infiltrate during
    this lull period, there could be a period of freezing drizzle,
    even north of I-40, before the next heavy round arrives. This will
    have to be monitored closely over the next 24 hours. The second
    round of moderate to heavy precipitation is anticipated to arrive
    mid to late evening Saturday as a Baja Low moves onshore over
    northwest Mexico and merges with the main upper level trough over
    the Great Basin/Dessert Southwest. This second round will persist
    overnight Saturday and through at least mid to late morning
    Sunday, perhaps lingering into the afternoon for portions of
    western AR before shifting east. Additional snowfall amounts
    between 4 and 8 inches can be expected north of I-40 during this
    period, with generally 2 to 4 inches of a mix of sleet and snow
    south.

    Total snowfall amounts from Friday night through Sunday afternoon
    will generally range between 8 and 12 inches near and north of
    I-40. However, guidance, especially hi-res guidance, has been
    persistent in showing periodic high snowfall rates (1 to 2 inches
    an hour) from intense snow bands. Localized snow amounts 15 to 20
    inches cannot be ruled out in a few locations, especially if any
    convective snow bands setup. These amounts do include sleet too,
    but sleet accumulations should stay below an inch at this time.
    South of I-40, sleet amounts are expected to overpower any snow
    accumulations, with up to 4 inches of sleet piling up for a few
    locations. The best chance of snow south of I-40 will actually
    occur Sunday morning, once the 850mb front is able to push south
    across southeast OK. This is where 2 to 3 inches of snow may fall
    on top of any ice and sleet that has fallen. As for ice amounts,
    as mentioned above, the highest probabilities for freezing rain
    will occur in Choctaw and Pushmataha counties, where anywhere from
    a glaze to a few tenths of an inch will be possible, mainly
    falling late Friday night into Saturday morning. This could result
    in localized power outages for this area. This event will have
    very high impacts for everyone, regardless how much snow, sleet,
    or ice falls. And they will fall. Travel will be extremely
    difficult to impossible at times, especially during the heaviest
    precipitation and before things start to melt. Stay home this
    weekend, if possible.

    Temperatures and especially wind chill temperatures will become
    dangerous north of I-40 by Friday night and spreading south of
    I-40 by Saturday morning. Actual high temperatures Saturday and
    Sunday will mainly be in the teens. Meanwhile, overnight lows will
    fall to the single digits Friday night for the majority of the
    area and for all of the area Saturday night. The coldest night is
    expected to be Sunday night into Monday morning after the storm
    system departs, winds calm down, and skies begin to clear. Strong
    radiational cooling will occur at the same time when there is
    potentially several inches of snow/sleet on the ground. Actual
    temperatures will fall well below zero for most locations, save
    near the Red River, Sunday night into Monday morning. Breezy
    northerly winds Friday night through Sunday evening will
    contribute to wind chills below zero or in the single digits for
    much of the forecast area between Saturday morning and Sunday
    night. Please remember to protect vulnerable people, pets, plants,
    and pipes over the next several days. Use space heaters and
    generators properly.

    Temperatures will be slow to rise after Monday. Temps are expected
    to finally rise above freezing (briefly) Tuesday afternoon and
    again Wednesday afternoon. This likely will not be enough to melt
    all of the snow and sleet on the ground and any melting that does
    occur will likely refreeze both Tuesday night and Wednesday night
    when temperatures fall back below freezing. Any existing snow and
    sleet on the ground will compact, keeping road conditions less
    than ideal through the remainder of the workweek. Good news is
    that no additional precipitation is expected beyond Sunday.

    .KEY MESSAGES...
    Updated at 1129 AM CST Fri Jan 23 2026

    - A very high impact winter storm will arrive tonight through Sunday,
    bringing climatologically extreme snow and sleet totals to the
    entire forecast area.

    - Life threatening cold will also develop tonight, continuing through
    Monday morning. Lows Monday morning will be near or below
    zero.

    - Travel will become very difficult to nearly impossible at times.

    - Temperatures will be slow to moderate next week, so societal
    impacts will persist for several days.

    .SHORT TERM...
    (Through tonight )
    Issued at 1129 AM CST Fri Jan 23 2026

    An arctic front has moved through the forecast area. Very cold and
    dry air is pouring in from the north. Northerly winds will gust to
    25-35 mph through the remainder of the day. Temperatures will remain
    below freezing for northeast OK and northwest AR through the
    afternoon. Areas south of I-40 will gradually cool to freezing by
    late afternoon. Meanwhile, precipitation will slowly spread north
    during the afternoon and evening hours. The initially dry lower
    levels will limit precipitation potential, especially in the north.
    Most model guidance shows precipitation reaching the ground by late
    afternoon or early evening for southeast OK, spreading to the
    remainder of the area during the late evening.

    By late evening, surface temperatures will be in the teens north of
    I-40, and 25-30 F south of there. This is expected to result in
    mostly snow (some sleet may mix in) for northern areas. The forecast
    is more uncertain for central and southern areas, with a gradual
    transition from mostly snow to mostly sleet heading south. Some CAM
    guidance shows mostly snow in the McAlester to Fort Smith Corridor,
    and if this occurred it could snow upwards of 8-12 inches tonight.
    But there is other guidance showing mostly sleet, so in this case
    perhaps a couple of inches of sleet would fall instead. Some of
    these differences can be tied to model microphysics differences
    rather than actual meteorological uncertainty. As the exact corridor
    of transition will likely be variable, trended the forecast to more
    of a blend of sleet and snow for a good chunk of central and
    southeast OK as well as west-central AR. Any freezing rain should be
    limited to far southeast OK, and even there sleet will dominate. A
    few rumbles of thunder may occur in southeast OK where there are
    hints of minimal convective instability. Models have commonly
    underestimated this threat in similar patterns in the past. In terms
    of intensity, snowfall rates in the heavier bands may reach as high
    as 2 inches per hour, creating extremely treacherous travel
    conditions.

    There is a clear trend in 12z model guidance for lighter
    precipitation tonight north of the I-44 corridor, with the heaviest
    axis of precipitation shifted south. The current forecast was
    updated to slightly tamp down on precip totals to reflect this, but
    it does not change the overall messaging of high impact winter
    weather that will occur. Future shifts may continue with further
    adjustments if these trends continue. For central and northern
    areas, total snow through Saturday morning will range from 3 to as
    much as 12 inches. Sleet totals will range from 1-3 inches, with
    central OK and west-central AR seeing a mixture of both types as
    noted earlier. Freezing rain accumulations will mostly be 0.15
    inches or less and right near the Red River. Temperatures by
    Saturday morning will be in the single digits in the north, and
    teens in the south. Wind chills Saturday morning may reach -5 to -15
    F north of I-40, and +9 to -5 F south of there.

    &&

    .LONG TERM...
    (Tomorrow through Friday)
    Issued at 1129 AM CST Fri Jan 23 2026

    Light snow and sleet will diminish Saturday morning. Most guidance
    is now in agreement on a break for most if not all of the forecast
    area Saturday late morning into mid afternoon. Southeast OK would
    have the best chance of light sleet persisting through this period. Temperatures will remain bitterly cold, generally pretty close to 10
    F in the north, and 15-20 F in the south. It will remain breezy with
    very low wind chills.

    By mid afternoon Saturday the next phase of this storm system will
    commence. Model trends this morning have shifted the 2nd
    precipitation band slightly southeast and slightly drier. They have
    also trended towards pulling sleet slightly further north at onset,
    perhaps as far north as a line from Okmulgee to Fayetteville. But
    even if this does occur, sleet will transition to snow for all areas
    by Sunday morning. With cooling upper levels the snow ratios are
    expected to become excellent, perhaps 15-1 or better near the end of
    the storm. This second phase will drop another 3 to 12 inches of
    snow in the north and up to 1-3 inches of sleet in the south (may
    end up being more snow than sleet). Overall storm totals will mostly
    be between 6 and 16 inches of snow (central and north) with 2-4
    inches of sleet in the south, with blending expected in the middle.
    An isolated storm total of up to 20 inches is possible, but not
    expected. Snow will end by Sunday early afternoon.

    Skies will clear Sunday night with winds going nearly calm.
    Considering these factors and a deep snowpack, low temperatures will
    fall to zero or below for the entire forecast area. Some typically
    cold areas may fall below -10 F. Any slight breezes will make it
    feel even colder. Temperatures will probably climb into the low to
    mid 20s Monday and perhaps above freezing for a few hours Tuesday or
    Wednesday afternoon before an additional push of cold air arrives.
    This will then keep high temperatures below freezing with lows in
    the teens into at least late week. Unfortunately this implies that
    very little of what falls will melt until at least late next week,
    with road conditions remaining extremely poor until at least then.
