Areas affected...southeastern Oklahoma

Concerning...Freezing rain 

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. 

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.
