KEY MESSAGES

Issued at 139 PM CDT Sat Aug 22 2026

- Heat Advisory from 1PM to 7PM.

- Major to Extreme 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 139 PM CDT Sat Aug 22 2026

A high that is located around the Four Corners region, will meander south-southeastwards slightly by next week. This will promote very dry rain free conditions outside of occasional isolated seabreeze convection daily. After some analysis, the decision was made to issue a heat advisory for the Coastal Bend extending into the Victoria Crossroads. This will be due to air temps already around 90 degrees at 10 AM, dew points in the mid to upper 70s, and the expected lack of cloud cover with relatively weak winds. Heat indices will be up to 112 through this evening. Expect these conditions to persist through the next week. Therefore we will continue to monitor for short-fused heat related products. We could see heat indices near 115 by midweek. This translates to moderate to predominately major HeatRisk conditions, though some areas of extreme HeatRisk will be possible in the Brush Country. We strongly encourage the practice of heat safety in these conditions. Take frequent breaks and remember to stay hydrated, check those backseats, and avoid long exposure in these temperatures. For more information be sure to check out weather.gov/heatsafety.

Late next week, guidance is hinting at the potential for a disturbance to sneak around the eastern periphery of the ridge. This could combine with some returning moisture to provide some relief. We will continue to hold our breath on this possibility due to it being so far out unfortunately. In the meantime, stay cool everyone!

AVIATION

(18Z TAFS) Issued at 139 PM CDT Sat Aug 22 2026

Expect VFR conditions to dominate the period. Though some periods of MVFR CIGs and VSBYs will be possible around daybreak at a couple of the eastern terminals (ALI and VCT). Winds will be out of the south- southeast through tomorrow with speeds up to 25 knots today. Lighter winds expected tomorrow.

MARINE

Issued at 139 PM 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.
