KEY MESSAGES

Issued at 119 AM CDT Thu Jul 30 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 119 AM CDT Thu Jul 30 2026

An expansive mid-level ridge will remain the dominant weather feature through the period, though it will gradually retrograde farther west this weekend and become centered over the lower Colorado River Valley. This will allow slightly deeper moisture to return to South Texas and weaken the subsidence enough to support isolated showers and thunderstorms on Sunday, with rain chances increasing to around 20-25% across much of the forecast area. Despite the uptick in rain chances, widespread wetting rainfall is not anticipated.

Hot conditions will persist through the forecast period with daytime highs generally in the upper 90s to around 105 degrees inland. While forecast heat indices have trended slightly lower for Saturday and Sunday compared to previous forecasts, widespread values of 110+ degrees remain likely, and Heat Advisories will probably be needed. Heat Risk continues to range from moderate to major with isolated areas of extreme remain possible through the weekend. Otherwise, little day-to-day change is expected as generally dry conditions prevail outside of isolated convection late in the weekend and early next week.

AVIATION

(06Z TAFS) Issued at 119 AM CDT Thu Jul 30 2026

Brief periods of MVFR CIGs will continue through 12-14Z. Otherwise, VFR conditions will prevail a majority of the TAF cycle. S-SE winds will be gusty, mainly in the afternoon and evening with gusts 22-28 knots.

MARINE

Issued at 119 AM CDT Thu Jul 30 2026

A gentle to moderate onshore flow will persist through the forecast period becoming occasionally fresh at times. Seas generally around 2 to 4 feet. Isolated showers and thunderstorms will become possible mainly over the northern waters beginning Sunday as moisture increases, but otherwise no significant marine hazards are expected.

FIRE WEATHER

Issued at 119 AM CDT Thu Jul 30 2026

Hot and dry conditions will continue across South Texas through the forecast period. Elevated fire weather conditions will remain possible across the western Brush Country through the end of this week where minimum RH values fall into the 20 to 30 percent range and fuels continue to dry out. However, light to occasionally moderate winds should limit the overall fire weather threat, with no critical fire weather conditions expected at this time.
