KEY MESSAGES

- Dangerous heat stress will persist through Monday.

- There is a marginal risk (level 1 of 5) for severe storms this afternoon and evening.

DISCUSSION

Issued at 341 AM CDT Sun Sep 6 2026

Today through tonight: Areas of fog are focused over the lower Pine Belt region early this morning, and this will persist to around sunrise. Otherwise, expect another day of dangerous heat and have maintained the heat advisory that is in effect for the entire area. Quick amplification of the upper level trough over the eastern CONUS will sent a front toward our forecast area. There will be some added compressional heating ahead of the boundary with H850 temperatures in the low 20s deg C, and this will result in continued elevated dangerous heat levels. A marginal severe risk has emerged for this afternoon/evening as scattered storms should initiate ahead of the front in an airmass characterized by steep low to mid level lapse rates. This will support severe wind gusts in the more intense storms. If storm development becomes more imminent, we could certainly see the risk level increase to slight (2 of 5) as there is recent precedence for storms to overachieve with the hotter days and anomalously hot H850 temps.

Monday through Saturday: A stubborn subtropical ridge will remain planted over the Gulf Coast states, so don't expect signs for early fall weather to show up any time soon. Instead, we can expect additional limited to elevated dangerous heat threats and reduced rainfall coverage mostly limited to southern portions of the area. /EC/

AVIATION

(12Z TAFS) Issued at 618 AM CDT Sun Sep 6 2026

VFR prevails. There is a high chance for thunderstorm development this afternoon north of I-20. These storms will weaken as they push south into the evening and eventually diminish around 3z. There will once again be the potential for low stratus/vis south of I-20, but given this has struggled to materialize the past couple mornings, have chosen to leave this out of the TAF for now. /SAS/
