KEY MESSAGES

Issued at 126 PM CDT Sat Aug 15 2026

- Moderate to major risk of heat-related impacts through next week with peak afternoon heat indices around 110

- Monitoring daily elevated fire weather potential over the Brush Country

DISCUSSION

Issued at 126 PM CDT Sat Aug 15 2026

The mid-level ridge over SE CONUS will move westward tomorrow (Sunday) and center over Texas, leading to increased subsidence, hot, and generally rain-free conditions through next work week. We can't completely take out the chance for a couple showers or storms developing along the afternoon seabreeze. Highs will continue to range from 90 along the coast to 105 over the Brush Country, with heat indices peaking around 110 each afternoon over the Coastal Plains. Therefore a moderate to major risk of heat-related impacts will continue over South Texas for the foreseeable future with UiL WBGT risks mainly moderate to occasionally high. In addition to heat concerns, we'll be monitoring the potential for elevated fire weather conditions daily over the Brush Country where winds over 20 mph may coincide with relative humidity less than 30% in the afternoon to early evening hours.

A mid to upper level trough over the Great Lakes region late next week tries to extend south into Texas, but no direct influences are expected over South Texas next weekend at this time. In fact, another strong mid-level ridge may quickly replace and center over the southern CONUS.

AVIATION

(18Z TAFS) Issued at 126 PM CDT Sat Aug 15 2026

VFR conditions prevail across South Texas this afternoon with FEW- SCT at around 4000 feet. Southeasterly winds sustained around 15 with gusts around 25 knots will continue into the early evening hours before weakening below 10 knots overnight. MVFR ceilings and vsbys are possible again between 09-13Z over ALI/VCT with MVFR ceilings also threatening into COT/CRP through 15Z. Winds will be around 5 knots weaker at the end of the forecast compared to today.

Issued at 126 PM CDT Sat Aug 15 2026

Gentle to moderate southeasterly flow will persist through next week, with occasional fresh flow south of Port Aransas returning the middle of next week. Minimal rain chances through next week.
