KEY MESSAGES

Issued at 121 PM 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 121 PM 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 mid-level trough rounding the northeastern periphery of this ridge is expected to amplify over the Ohio Valley on Sunday, slightly eroding the eastern edge of the aformentioned ridge. As a result, we can expect increased mid-level moisture and small scale ascent across the region. Even so, shower and thunderstorm chances will remain low, ranging from 15-20% on the high end, mainly across the Coastal Plains and Brush Country.

A continuation of temperatures in the mid to upper 90's along the coast and 100+ elsewhere is expected to hold into early next week. While widespread heat indicies will remain below 110 degrees, a moderate to major (2 & 3) HeatRisk will remain in play the entire forecast period. These temperatures, coupled with gusty winds, have resulted in an increased fire risk for the western Brush Country. Conditions may improve Sunday with a chance for rain over the area.

AVIATION

(18Z TAFS) Issued at 121 PM CDT Fri Jul 31 2026

Gusty winds up to 25 knots expected this afternoon across all terminals keeping VFR conditions prevailing into the evening. I have high confidence that ALI/VCT will briefly see MFVR CIGs/VSBYs early Saturday morning, though CRP a little less so. COT may also see very brief MVFR CIGs, but confidene isn't high enough to include a TEMPO.

MARINE

Issued at 121 PM 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.
