   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.
