DISCUSSION

Issued at 121 PM CDT Mon Aug 24 2026

We have sounded like the broken record for the past week and I am sorry, but still no changes. An area of high pressure remains centered near the Four Corners region, meandering south-southeast through the week, keeping us hot and dry through the end of the week. There is a very low chance of some seabreeze convection in the afternoons, though this is pretty slim. Guidance is still hinting at the potential for a disturbance to sneak around the eastern periphery of the ridge around the Friday timeframe. This could lead to some isolated showers and slightly cooler temperatures but, again, this is still pretty far out so we are not getting our hopes up.

Thanks to the presence of below normal moisture today and tomorrow which will help keep heat index values slightly below 110 for most of South Texas. Will maintain not issuing a heat advisory today, though will monitor for a short-fused advisory tomorrow. Moisture will begin to gradual return Wednesday through the end of the week, resulting in higher heat index values once again. Heat Advisories will likely be needed Wednesday through the end of the week. Regardless of the slightly lower heat index values, we urge you all to be extremely cautious if you are outside. Cumulative heat stress can lead to increased chances for heat exhaustion or heat stroke. Remember to take breaks in the shade or air conditioning, drink water/electrolytes, and pace yourself if working outside. Don't leave children or pets in your vehicle, even for short periods of time.

AVIATION

(18Z TAFS) Issued at 121 PM CDT Mon Aug 24 2026

VFR conditions will be expected to prevail through the period. Some brief periods of MVFR CIGs and VSBYs will be possible once again in the east Tuesday morning around 08-09Z (VCT and ALI). Winds will be breezy this morning gusting up to 25 knots. They will decrease this evening becoming generally light through the remainder of the period.

MARINE

Issued at 121 PM CDT Mon Aug 24 2026

Expect 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 through the middle of the week. Mariners should take steps to prevent heat illness as hot temperatures continue.

FIRE WEATHER

Issued at 127 AM CDT Mon Aug 24 2026

ERC values have increased across the Brush Country to the 90-96th percentile, with most of the rest of the area in the 70-89th percentile. Humidity values will continue to be low, with minimum RH values below 34% over the Coastal Plains and Brush Country. Winds will remain fairly light, but given the hot temperatures, low relative humidity, and high ERC values, have issued a Fire Danger Statement for most of the area through this evening. Should winds increase more than anticipated, a few locations could experience critical fire weather concerns.
