KEY MESSAGES

Updated at 1200 AM CDT Fri Aug 7 2026

- Continued hot and dry for most of South-Central Texas for the next seven days.

- A few spots in the Coastal Plains could reach Heat Advisory criteria briefly during the afternoon today and tomorrow.

- There will be a slight chance for showers or thunderstorms over the Coastal Plains during the afternoon today and tomorrow.

- There will be a slight chance for showers or thunderstorms over the Coastal Plains this afternoon and for the next several afternoons including the weekend.

SHORT TERM

(Tonight through Friday night) Issued at 1200 AM CDT Fri Aug 7 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 there won't be any significant change in the pattern. Expect another hot and mainly dry day with high temperatures about the same as Thursday. 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. The upper ridge will be weak enough to allow isolated showers and thunderstorms to form over the Coastal Plains and move inland. Thursday afternoon we saw storms move to the I-35 Corridor, but it looks like they won't make it that far inland today. Saturday will be another repeat. Hot, mainly dry with isolated showers and thunderstorms moving inland from the Coastal Plains. Storms could reach I-35 again.

LONG TERM

(Saturday through next Thursday) Issued at 1200 AM CDT Fri Aug 7 2026

Sunday and Monday the stagnant pattern will continue. High temperatures will stay hot and near normal both days. 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. A few showers or thunderstorms could move over the Coastal Plains each afternoon. As the ridge shifts back toward the southeast, rain chances will come to an end Tuesday. Temperatures will creep up a bit into the middle of next week. The higher temperatures combined with the humidity may produce Heat Advisory criteria across the area south of I-10 and east of I-37.

AVIATION

(06Z TAFS) Issued at 1240 AM CDT Fri Aug 7 2026

Breezy late afternoon and evening conditions should help maintain persistence weather with overnight stratus returning to the SAT/SSF/AUS areas between 08Z and 10Z and DRT to pick up an MVFR CIG by around 14Z. VFR skies should return by around 18Z and another afternoon of isolated storms are expected by 21Z. Main impacts of the convection will be outflow boundaries, so in this update, will avoid chasing the timing and location for convection which should be mostly east of I-35.
