   Areas affected...Central/North-Central TX

   Concerning...Freezing rain 

   Valid 091730Z - 092130Z

   SUMMARY...Freezing rain will be possible across portions of central
   and north-central Texas, with from 0.05" to 0.10" expected over the
   next several hours.

   DISCUSSION...Regional radar imagery shows increasing precipitation
   coverage across southwest TX, coincident with strengthening warm-air
   advection and large scale ascent ahead of the shortwave trough
   moving out of northern Mexico. The northeasterly motion of this area
   of precipitation should continue, taking it into
   central/north-central TX over the next few hours. Temperatures
   across central/north-central TX are near freezing, but an additional
   degree or two of cooling is possible as precipitation cools the
   column, helping to offset some of the low-level warm-air advection.
   As such, the surface wet-bulb temperature, which has been gradually
   shifting northward, will likely stall along its current location,
   which is roughly along a line from BBD to SLR. Freezing rain will be
   possible north of this line over the next several hours, with total
   precipitation from 0.05" to 0.10" expected.
