    Areas affected...southeastern Oklahoma

    Concerning...Freezing rain=20

    Valid 220106Z - 220500Z

    SUMMARY...Increasing potential for freezing rain with potential for
    quick ice accumulations.

    DISCUSSION...A region of light to moderate precipitation is observed
    moving northeastward into southwestern Oklahoma over the last hour.
    Surface temperatures are hovering around freezing near the Red River
    with a drop into the upper 20s moving northeast. With dew points in
    the teens, further reduction of temperatures through wet-bulb
    cooling can be expected as the heavier precipitation moves
    northward.=20

    The 00z sounding from OUN shows a pronounced warm nose from 925 mb
    to around 800 mb with surface temperatures below freezing. Though
    some dry air remains around 750 mb and near the surface, the profile
    has moistened. It is noteworthy that hi-res guidance is generally
    running a little warm over the last 12-24 hours in trends when
    compared to RTMA. The RAP and HRRR seem to be coming into better
    alignment with current conditions over the last 3-6 hours.
    Expectation is for freezing drizzle and rain to increase in coverage
    over the next few hours across southeastern Oklahoma. Locations
    that are already below freezing will likely see quick icing,
    especially across elevated surfaces. Given that ground temperatures
    are already below freezing, this will likely impact travel with
    slick conditions developing quickly through the next few hours.
