.SHORT TERM...
(Tonight through Thursday night)
Issued at 110 PM CDT Wed Mar 11 2026

An upper low is moving over South Central Texas early this afternoon
which is evident on satellite with some wrap around clouds moving
in from the north over over the southern Edwards Plateau. The
main line of showers and thunderstorms from this morning has moved
east of the area with predominantly dry conditions expected the
rest of the day. Only low PoPs remain over the northeastern
portion of our coastal plain counties late this afternoon given
forcing from the upper low and a southward moving Pacific front. A
quick shower or isolated thunderstorm could develop but no severe
weather is expected.

The aforementioned cold front will make its way through the area
today with gusty northerly wind behind this feature. The pressure
gradient remains tight as the upper low ejects east and surface
high pressure drops into North Texas tonight. Gusty wind will
continue over the area overnight with gusts approaching 35-40 mph
at times, only dropping off in the west after midnight. With
cooler air moving into the region behind the front, wind chill
values will drop down into the low to mid 30s over the Hill
Country and southern Edwards Plateau and into the upper 30s to
upper 40s elsewhere.

Surface high pressure will reside over the area by tomorrow
afternoon bringing lighter wind and clear skies with cooler highs
in the 60s to low 70s. Clear skies and light wind remain Thursday
night into Friday bringing lows down into the 40s across all of
South Central Texas.

.LONG TERM...
(Friday through next Wednesday)
Issued at 110 PM CDT Wed Mar 11 2026

High pressure shifts east of the area Thursday night with southerly
flow back in place by Friday. A day by day warming trend is expected
through Sunday when highs peak from the upper 80s to mid 90s. If
you`re not ready for summer quite yet, then good news arrives in the
form of a strong cold front making its way across the area Sunday
night. Gusty wind behind the front will usher in cooler temperatures
with highs Monday forecast in the 60s. Temperatures fall into the
30s and 40s Monday night, then another warming trend is seen through
the end of the forecast. Dry weather is expected into the middle of
next week.

.AVIATION...
(00Z TAFS)
Issued at 634 PM CDT Wed Mar 11 2026

Isolated TSRA/SHRA near GYB and vicinity will move east out of
the area by 03Z as a front pushes southward across the region.
Satellite imagery shows haze/dust spreading south near DRT, but
VSBY impacts are not expected. Winds are in the process of
shifting to northerlies regionwide with 15-20 kt flow expected
tonight for at all area terminals. The likelihood of sustained
winds exceeding 20 kt for brief periods of time is low to
moderate, around 30 to 50 percent. Brisk 20 kt winds have already
reached DRT and vicinity, but local terrain effects are expected
to allow winds to weaken overnight. Elsewhere, winds remain gusty
through the night but will begin to veer northeasterly and weaken
particularly after 18Z. VFR conditions prevail through the TAF
period.
