Areas affected...Central/North-Central TX

Concerning...Freezing rain=20

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.
