KEY MESSAGES

- Daily elevated fire weather conditions over the Brush Country

DISCUSSION

Issued at 131 PM CDT Sun Aug 23 2026

A high that is located around the Four Corners region, will meander south-southeastwards slightly through the week. This will promote very dry rain free conditions outside of occasional isolated seabreeze convection daily. Heat indices will be up to 113 today once again. This is expected to persist through the 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.

With the presence of high ERCs and low relative humidity values across inland South Texas, elevated fire weather conditions will be expected today. Due to this a Fire Danger Statement was issued through 10 PM tonight. Though winds are expected to be light, fires will be able to be easily ignited.

Late this 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 hold our breath on this possibility due to it being still too far out. In the meantime, stay cool everyone!

AVIATION

(00Z TAFS) Issued at 551 PM CDT Sun Aug 23 2026

Continued VFR conditions, with periods of MVFR visibility/ceilings at ALI and VCT from 08Z-12Z so have left TEMPO groups in for this.

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.
