   Areas affected...Portions of northeast Texas into far southeast
   Oklahoma and far southwest Arkansas

   Concerning...Freezing rain 

   Valid 092106Z - 100100Z

   SUMMARY...Freezing rain and perhaps some snow/sleet mix will
   continue spreading northeastward across northeast Texas into the
   early evening. Some locations could see freezing rain rates around
   0.10 inch/3 hours.

   DISCUSSION...Recent mosaic radar data shows a swath of mixed winter
   precipitation spreading northeastward across north-central TX --
   where surface temperatures are hovering around 32-33F. Within a belt
   of strong deep-layer southwesterly flow, and at the nose of an
   eastward-shifting plume of warm advection, this activity will
   continue expanding across northeast TX into this evening. Here,
   forecast soundings indicate a deep/saturated profile with a
   warm-nose temperature around 0.1-0.2C atop sub-freezing surface
   conditions -- favoring partial melting of descending hydrometeors.
   This should support primarily freezing rain, though some mix of
   sleet/snow will also be possible. Freezing rain rates around 0.10
   inch/3 hours will be possible in some locations across northeast TX
   into far southeast OK and southwest AR through the evening.
