KEY MESSAGES

Issued at 123 AM CDT Sat Aug 22 2026

- Major risk of heat-related impacts continue into next week with peak afternoon heat indices around 110

- Daily elevated fire weather conditions over the Brush Country

DISCUSSION

Issued at 123 AM CDT Sat Aug 22 2026

Hot and rain-free conditions will continue through the weekend as high pressure persists. Fortunately, moisture will be limited through the weekend, which will help limit some of our heat concerns. That being said, it will still be very hot. Heat index values will still range from 105 to nearly 110 through Monday. Moisture starts to slowly increase beginning Tuesday, which will increase heat index values once again.

Precipitation chances will remain near zero through Monday, but we still can't rule out an isolated shower along the seabreeze. Chances will increase slightly, though still remain below 10% Tuesday through the latter part of next week as moisture increases. The hope on the horizon is that the ridge may shift just enough to allow a trough to sneak under the eastern edge which could serve to cool things down ever so slightly and could increase the chances of rain to nearly mentionable. This is still very questionable, but we can hope.

Continue to practice heat safety: look before you lock, limit outdoor exposure, drink plenty of water, and take frequent breaks. For more safety information please visit weather.gov/heatsafety.

AVIATION

(06Z TAFS) Issued at 123 AM CDT Sat Aug 22 2026

The overall forecast remains the same. VFR conditions will persist, with some brief MVFR/IFR ceilings/visibility for ALI and VCT from around 09Z-14Z. Generally south to southeast winds will be below 12 knots overnight, then increases to 10-15 knots with gusts to 20-25 knots Saturday afternoon.

MARINE

Issued at 123 AM CDT Sat Aug 22 2026

Light to moderate (BF 2-4) onshore breezes will continue through the period, with occasional fresh (BF 5) breezes possible during the late afternoon/evening hours, especially south of Port Aransas. Seas are expected to remain around 2-3 feet. Rain chances will remain near zero into next week.

FIRE WEATHER

Issued at 123 AM CDT Sat Aug 22 2026

ERC values are in the 75-89th percentile, with low humidity, dry to critically dry fuels, and hot temperatures, leading to elevated fire weather conditions over the Brush Country and portions of the Coastal Plains. Conditions will need to be closely monitored as a few locations across the Brush Country could even see critical fire weather conditions into next week.
