KEY MESSAGES

Updated at 619 AM CDT Mon Jul 27 2026

- Moderate to major risk of heat persists across South Texas throughout the period, with localized extreme heat risk developing across portions of the Brush Country later this week.

- Elevated fire weather conditions may develop across portions of the northwestern Brush Country during the middle to latter part of the week.

DISCUSSION

Issued at 121 AM CDT Mon Jul 27 2026

A mid-level ridge will remain firmly in place over South Texas through the forecast period, supporting a prolonged stretch of hot and dry weather. While low-level moisture will keep dewpoints in the mid to upper 70s across much of the area, subsidence beneath the ridge will suppress rainfall and favor mostly clear to partly cloudy skies. Afternoon highs will generally range from the mid 90s near the coast to around 105 degrees across the Brush Country.

The primary concern remains the increasing heat. Heat index values in the 105-112 degree range are expected most afternoons, with localized values approaching 115 degrees possible later this week, especially along the Coastal Bend and the Coastal Plains. HeatRisk will remain moderate for much of the area while increasing to major, and locally extreme across portions of the northern Brush Country, by late week. Those without adequate cooling or hydration will be most susceptible to heat-related illness.

AVIATION

(12Z TAFS) Issued at 619 AM CDT Mon Jul 27 2026

VFR conditions have persisted all all sites so far this morning, but could still see brief MVFR conditions at eastern sites. VFR conditions are expected through the day with a breezy southeasterly wind in the afternoon. Feel that chances for MVFR tonight are limited and have not included in TAFs at this time.

MARINE

Issued at 121 AM CDT Mon Jul 27 2026

A persistent onshore flow will continue through the period. Winds will generally remain gentle to moderate (BF 3-4), becoming fresh (BF 5) during the evening and overnight hours. Seas are expected to hold between 2 - 4 feet with little day-to-day change. Rain chances remain near zero through the forecast period.

FIRE WEATHER

Issued at 121 AM CDT Mon Jul 27 2026

Dry weather will persist through the period as high pressure remains in control. Minimum RH values will fall into the mid to upper 20% range across the northwestern Brush Country by midweek while remaining around 30% elsewhere across the Brush Country. Although 20- foot winds should remain below 15 mph, a combination of hot temperatures, lower humidity, and ERC values increasing into the 50th to 60th percentile range may result in localized fire weather conditions across portions of the northwestern Brush Country. Widespread critical fire weather conditions are not expected at this time.
