Issued at 1120 PM CST Tue Dec 2 2025
West-southwesterly mid-level flow continues to send Pacific
moisture into the region in the form of mid to upper level clouds
this evening. Mostly dry weather is expected today with the
exception possibly being over the Coastal Plains late this
afternoon through Wednesday night as surface moisture increases
ahead of the next approaching trough. Showers and perhaps a rumble
of thunder will develop over the Coastal Plains towards sunset
Wednesday and primarily remain over this region through early
Thursday morning. A long wave trough approaches the Panhandle on
Thursday, sending a series of weak shortwaves through the west-
southwesterly flow aloft. This will result in much cooler
temperatures Thursday along with showers and some isolated
thunderstorms through the day.

.LONG TERM...
(Thursday through next Tuesday)
Issued at 1120 PM CST Tue Dec 2 2025
The aforementioned trough will remain stretched out over the Baha of
California on Friday, resulting in continued surface moisture
teaming up with a mid-level disturbance and moisture to produce
showers again on Friday. This long wave trough should finally eject
out over the southern plains on Saturday, allowing a nice drying and
warming trend for the weekend. Beyond the weekend, a warmer than
normal pattern is expected to develop through the middle of December
with minimal rain chances.

(12Z TAFS)
Issued at 537 AM CST Wed Dec 3 2025
Gulf moisture return is slightly ahead of schedule in bringing SCT
V BKN MVFR CIGS into the I-35 Corridor. The VAD winds would
suggest they will remain well east of DRT for today, but we should
see 1000-2500 FT CIGs to fill in to become a thicker OVC layer the
deeper we go into the daytime. By this evening we should see the
CIGs dropping possibly to IFR by 00Z and possibly even into LIFR
or lower at times late in the evening. DRT should expect to see
some low clouds spread their way as a reinforcing cold front
arrives. This front should get to AUS shortly after 06Z and into
the SAT/SSF areas roughly an hour or two later. Timing of when the
winds kick up and raise CIGs and VSBYs slightly may not coincide
with the actual front arrival, but rather be delayed an hour or
two. With the light isentropic lift over the front the likelihood
of prevailing rain over I-35 increases, with AUS most likely to
see impacts before daybreak.
