KEY MESSAGES

Updated at 119 PM CDT Wed Jul 1 2026

- Moderate risk of heat-related impacts into early next week, afternoon heat indices of 100-108

- Daily spotty streamer showers and a few thunderstorms over the Coastal Plains

DISCUSSION

Issued at 119 PM CDT Wed Jul 1 2026

No significant changes from the previous forecast. NBM rain chances seem too low in the short-term across South Texas. Given current radar and expected increased moisture, I've bumped up rain chances to at least 15-20% over the Coastal Plains and Victoria Crossroads where enhanced moisture can lead to diurnally-driven spotty showers and thunderstorms in the morning and early afternoon hours.

Recent model runs have shown the mid-level ridge over the Four Corners region early next week being the more prominent feature for South Texas than the trough protruding southwestward from the Great Lakes. No clear signature for greater rain chances and can expect more of the same diurnally-driven convection. But we'll keep a close eye on mid-level support from Mexico or the aforementioned trough.

Temperatures will remain steady into early next week, with highs in the 90s to around 100 over the Brush Country, and lows in the mid to upper 70s. Afternoon max heat indices will range from 100-108 daily, leading to a moderate risk of heat-related impacts across South Texas.

AVIATION

(18Z TAFS) Issued at 119 PM CDT Wed Jul 1 2026

Spotty showers and a couple of thunderstorms have developed this afternoon along the seabreeze and streamers over the Coastal Plains. VCT has the greatest chance of seeing direct impacts from a shower, followed by ALI but confidence is not high enough to include in the forecast at this time. VFR conditions currently prevail across South Texas with MVFR ceilings expected to develop tonight mainly over the Brush Country, impacting COT/LRD/ALI. Light southeasterly winds will also allow for MVFR vsby to develop over the fog prone areas of ALI/VCT between 09-13Z. MVFR ceilings may linger over the area through mid-morning before VFR conditions prevail at all terminals by 16Z.

MARINE

Issued at 119 PM CDT Wed Jul 1 2026

Gentle to moderate south to southeasterly breeze (BF 3-4) will persist into early next week, with seas between 2 to 4 feet. There will be low rain chances each morning across the open waters.
