    Areas affected...west to north TX and southern OK

    Concerning...Winter mixed precipitation=20

    Valid 231855Z - 240000Z

    SUMMARY...A plume of mixed precipitation is expected to
    substantially increase into early evening from west to north Texas
    into southern Oklahoma. Sleet should be the primary precipitation
    type, with the freezing rain line gradually shifting south. Initial
    rates should generally be light, before increasing tonight.

    DISCUSSION...Initial swath of precipitation has been increasing over
    the past few hours across the South Plains to central TX. The
    northern extent of this precip shield is about to overspread a
    southward-moving nose of sub-freezing surface temperatures across
    the Low Rolling Plains, centered on the surface ridge over northwest
    TX. This should initially impact areas near to southeast of LBB, but
    will increase greatly in areal coverage by late afternoon into early
    evening. Light freezing rain should be anticipated where surface
    temps remain in the 29-32 F range. Sleet should be the overarching
    PTYPE through 00Z as low-level warm theta-e advection in the 850-700
    mb layer maintains an above-freezing warm nose atop the increasingly
    cold boundary layer. Pervasive surface dry advection will slow the
    northern extent of winter precip reaching the surface, especially in
    OK, through early evening. This should also aid in yielding
    generally light liquid-equivalent rates until tonight.
