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.

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.

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

ANother cold day with well below normal temps and wind chills in

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

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.

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

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

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.

A weak cold front will move into the region late tonight into

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.

Latest satellite imagery shows low/mid-level stratus continuing to
advect into the area from the south. Intermittent VFR/MVFR
conditions should transition to mostly MVFR after midnight at most
terminals. The stratus seems to stick around through much of the
morning Wednesday. Light to moderate rain showers will be possible
through mid-morning ahead of an approaching cold front, highest
chances mainly confined to the AR terminals as well as KMLC. Once
the front is able to push through, sometime mid-late morning
Wednesday, skies will clear and VFR will prevail through the
remainder of the forecast period. Winds will turn northerly, with
occasional gusts up to 20 knots initially behind the cold front.

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.

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.

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.

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.

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.

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

(Through Friday)
Issued at 1108 PM CST Thu Jan 22 2026
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!

(Friday Night through Thursday)
Issued at 1108 PM CST Thu Jan 22 2026
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.

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.

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.
