KEY MESSAGES

Updated at 546 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

(12Z TAFS) Issued at 546 AM CDT Fri Aug 7 2026

MVFR CIGs are coming off persistence this morning and so will favor even fewer clouds in the following day. Looks like most areas should mix to VFR by 15Z if not 14Z this morning, and the MOS guidances with a lighter wind trend going for the next 24 hours would suggest little or on low clouds for tonight.
