KEY MESSAGES

Issued at 123 AM CDT Wed Jul 29 2026

- Moderate to major risk of heat will continue across South Texas, with localized extreme heat risk possible across portions of the Brush Country. Further heat advisories may be necessary.

- Localized elevated fire weather conditions remain possible across the northwestern Brush Country, expanding over the Rio Grande Plains and adjacent areas by Thursday.

DISCUSSION

Issued at 123 AM CDT Wed Jul 29 2026

A mid-level ridge centered over the Desert Southwest will remain the dominant weather feature through much of the forecast period, maintaining hot and generally dry conditions across South Texas. Afternoon temperatures will continue to climb through the week, with HeatRisk remaining moderate to major through Friday before moderate expands over most of South Texas to locally extreme across portions of the Brush Country over the weekend. Although some locations may briefly meet Heat Advisory criteria on Wednesday, coverage appears too limited for an advisory at this time. Please continue to practice heat safety as heat indices around 110 and higher become increasingly common this week, especially this weekend with isolated locations across the southern Coastal Bend approaching 118 degrees.

Forecast confidence decreases slightly late Saturday into Sunday as a weak mid-level disturbance rounds the eastern periphery of the ridge, bringing a low (15-20%) chance around the Victoria Crossroads for showers and thunderstorms with most locations expected to remain hot and dry.

AVIATION

(06Z TAFS) Issued at 123 AM CDT Wed Jul 29 2026

A band of MVFR CIGS is moving northward into the region, but may remain between all TAF sites, just west of ALI. Later in the night though do expect the potential for MVFR CIGS for all sites for a few hours. Have tempo groups for this. The rest of the period will be MVFR for all sites with gusty winds in the afternoon once again.

MARINE

Issued at 123 AM CDT Wed Jul 29 2026

A gentle to moderate onshore flow will mainly persist through the period as ridging remains over the Gulf, with occasional fresh (BF 5) conditions during the evening and overnight hours. Seas will remain around 2-4 feet. Dry conditions are expected through the forecast period, with probabilities near zero, slightly increasing to around 15-20% over the northern offshore waters this weekend.

FIRE WEATHER

Issued at 123 AM CDT Wed Jul 29 2026

Hot and predominately dry conditions will persist through the forecast period. Minimum RH values will continue to fall into the 20- 35% range across portions of the Brush Country each afternoon while 2-foot winds generally remain below 15 mph. Elevated fire weather conditions will remain possible across the northwestern Brush Country during the latter half of the week before expanding across much of the western Brush Country Saturday through Monday as hotter temperatures overspread the region. ERC values remain in the 50th to 69th percentile, while RFTI values increase to around 3 across portions of Webb county and adjacent areas on Thursday. Although widespread critical fire weather conditions are not anticipated, any fires that develop could exhibit increased rates of spread where the driest fuels and lowest humidity overlap.
