KEY MESSAGES

Issued at 607 AM CDT Fri Jul 31 2026

- Moderate to major heat risk continues through the weekend across South Texas, with localized extreme heat risk possible across portions of the Brush Country. Further heat advisories are likely.

- Elevated fire weather conditions remain possible across the western Brush Country through late this week.

- Low rain chances return Sunday as moisture gradually increases across South Texas.

DISCUSSION

Issued at 120 AM CDT Fri Jul 31 2026

An expansive mid-level ridge centered over the Desert Southwest will remain the dominant weather feature through early next week, maintaining hot and predominately dry conditions across South Texas. A weak disturbance skirting the eastern periphery of the ridge may bring isolated showers and thunderstorms Sunday, mainly across the Coastal Plains and Brush Country, though coverage has trended lower with chances ranging from 15-20%. Otherwise, dry weather is expected through the remainder of the period.

Temperatures will continue to climb through the weekend into early next week with widespread triple-digit highs across the Brush Country and Rio Grande Plains. Although slightly lower dewpoints have reduced the areal coverage of advisory-level heat indices Friday and Saturday, moderate to major HeatRisk will remain common this weekend with isolated areas of extreme HeatRisk persisting into early next week. Continue to practice heat safety if spending time outdoors.

AVIATION

(12Z TAFS) Issued at 607 AM CDT Fri Jul 31 2026

Brief MVFR conditions have developed this morning across ALI, CRP and VCT. Otherwise, VFR conditions will prevail through much of the TAF cycle with brief periods of MVFR for ALI, VCT and COT once again early Saturday morning. S to SE winds will gusts to 20-28 knots today.

MARINE

Issued at 120 AM CDT Fri Jul 31 2026

A gentle to moderate onshore flow can generally be expected through the forecast period, with occasional fresh winds during the overnight and morning hours. Small Craft Should Exercise Caution conditions are expected with periods of Small Craft Advisory conditions over the nearshore waters and bays South of Port Aransas. Seas will generally range from 2-4 feet. Rain chances over the coastal waters remain very low, generally less than 10%, with no significant marine hazards anticipated.

FIRE WEATHER

Issued at 120 AM CDT Fri Jul 31 2026

Hot temperatures, dry fuels, and low afternoon relative humidity will continue to support periods of elevated fire weather conditions across the Brush Country through early next week. While winds remain relatively light, ERC values generally between the 50th and 69th percentile, RFTI values around 2 (locally 3 today), and normal to dry fuel conditions will support an elevated risk for fire spread, especially where the driest fine fuels exist. 10-hour fuel moisture values remain largely in the 11th-25th percentile, while 100-hour and 1000-hour fuels are generally in the 4th-10th percentile across much of South Texas.
