.SHORT TERM...
(Today through Friday)
Issued at 129 AM CDT Thu Aug 6 2026

The subtropical ridge is centered near the Four Corners region this
evening with weak anticyclonic flow over Texas. High pressure over
the Gulf is producing southeasterly flow in the low levels. The
airmass over South-Central Texas remains hot and moist. In the short
term the the center of the upper ridge will continue to drift to the
north. Expect another hot and mainly dry day with high temperatures
about the same as Tuesday. The combination of heat and humidity may
bring a few spots over the Coastal Plains to Heat Advisory levels
for a couple of hours, but we don`t expect enough coverage to issue
an advisory. As the upper high moves a little farther away to the
north there will be some minor height falls over Texas. This will
result in some very low POPs over the Coastal Plains this afternoon.
Still most places will be dry. High temperatures will be a degree or
two lower Friday as the upper ridge moves farther away. There will
continue to be slight chances for rain over the Coastal Plains
Friday afternoon.

.LONG TERM...
(Friday night through Wednesday)
Issued at 129 AM CDT Thu Aug 6 2026

The upper ridge will remain near the Four Corners region through
Monday. This will lead to a fairly stagnant forecast. High
temperatures will stay hot and near normal each day Saturday through
Wednesday. Humidity will remain low enough to keep heat indices
below Heat Advisory criteria, however a few spots in the Coastal
Plains could briefly reach criteria each afternoon. With upper ridge
farther north a few showers or thunderstorms could move over the
Coastal Plains each afternoon Sunday and Monday, but chances will be
mostly less than 20%. As the ridge shifts back toward the southeast,
rain chances will come to an end.

.AVIATION...
(12Z TAFS)
Issued at 537 AM CDT Thu Aug 6 2026

Only change needed was to include development of MVFR stratus once
again tonight into tomorrow morning at AUS, SAT, and SSF.
Confidence is lower at DRT, so opted for a scattered layer for
now. Otherwise, the forecast remains mostly the same with MVFR
cigs this morning, lifting to VFR by 16Z then winds picking up to
10-15 kts through the afternoon hours before turning lighter after
sunset.
