KEY MESSAGES

Issued at 619 PM CDT Thu Aug 6 2026

- Moderate to major risk of heat-related impacts through the week, with peak heat indices 105 to 110, and high to extreme WBGT values.

DISCUSSION

Issued at 159 PM CDT Thu Aug 6 2026

Spotty showers have been popping up in association with a surface shortwave trough and the arrival of the seabreeze. These will continue to be isolated in nature and taper off this evening. Mid- level high pressure will dominate the period leading to warm and mostly rain free conditions outside of isolated seabreeze convection each day. This is thanks to some midlevel energy riding the periphery of ridge as it builds from the east. Will continue to monitor the need for some short- fused heat related products. We could see heat indices up to 115 at times with dew points around the mid to upper 70s present through the next week. This translates to Moderate to Major heat stress conditions though we could see some areas reach Extreme conditions by Wednesday. 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.

AVIATION

(00Z TAFS) Issued at 619 PM CDT Thu Aug 6 2026

VFR conditions this evening become MVFR overnight and into early Friday. A few thunderstorms are noted this evening between ALI/COT/LRD. These shouldn't last too long and are unlikely to directly impact any of the terminals. VFR conditions return tomorrow with breezy afternoon winds, but not as gusty as they have been in recent days.
