KEY MESSAGES

Updated at 125 AM CDT Tue Jul 7 2026

- Warm temperatures persist through the end of the work week with most areas remaining dry.

- Increased moisture brings scattered showers and thunderstorms this weekend with perhaps a slight drop in temperatures.

SHORT TERM

(Today through Wednesday) Issued at 125 AM CDT Tue Jul 7 2026

A mid to upper level ridge extends from northwestern Mexico to the northern Great Plains with a trough from the Great Lakes to the ArkLaTex region. This was producing weak cyclonic flow over Texas. The remnants of a frontal boundary was over North Texas and winds on the south side of this boundary were from the southeast except where the pressure field has been disrupted by convection over the Edwards Plateau. Convection last evening cooled temperatures over the Hill Country, Edwards Plateau, and Rio Grande Plains. As the pressure field gets re-established the temperatures will recover. The overall pattern will change very little. The upper ridge will start to strengthen, but may still be weak enough for isolated showers and thunderstorms this afternoon. It looks like the most likely locations will be over the Rio Grande Plains and the Coastal Plains where the seabreeze could bring convection. Chances will still be around 20%. By Wednesday the upper ridge will once again be strong enough to suppress all convection. Temperatures through the short term period will be near normal.

LONG TERM

(Wednesday night through Monday) Issued at 125 AM CDT Tue Jul 7 2026

The upper ridge will strengthen further Thursday keeping the weather hot and dry. Temperatures will stay fairly steady. Friday another upper trough will ride over the ridge into the middle of the country and will weaken the ridge over Texas. This weakening of the ridge will coincide with a surge of moisture from the Gulf. The result will be chances for showers and thunderstorms beginning Friday afternoon and continuing until Monday. Right now the best chances look to be Saturday when the PW is forecast to be the highest. Although it's very early to talk about specific rain amounts, model PW forecast would suggest a chance for locally heavy rain. The trend tonight is for lower overall rain chances. With the weaker ridge over the weekend temperatures will be a few degrees lower over the weekend.

AVIATION

(06Z TAFS) Issued at 125 AM CDT Tue Jul 7 2026

Primarily VFR flight conditions will trend through the period at the TAF sites. An exception would be around the San Antonio terminals into and during early this morning, particularly at KSAT, as conditions could at times fluctuate between a sct and bkn low-level deck with MVFR ceilings. Otherwise, there will be some mid to high level clouds mixed in as well. Rain chances today would be lower than yesterday but a stray to isolated shower could still develop. Coverage and confidence are too low to include in the TAF package. Winds speeds will remain of around 10 kt or less but a few occasional higher gusts will occur at times during the afternoon and evening timeframe, especially with any nearby shower or outflow boundary.
