KEY MESSAGES

Issued at 652 PM CDT THU SEP 3 2026

- Significant Heat Risk: A warming trend will push heat indices to 105-108 each afternoon into the weekend. A Heat Advisory is now in effect through 8PM Saturday.

DISCUSSION

(This afternoon through Wednesday) Issued at 201 PM CDT THU SEP 3 2026

Upper level ridge remains the big story for our weather, helping push temperatures up close to 100 degrees in many areas again this afternoon. A few showers/storms have also popped up in the heat of the afternoon. The big upper ridge is still forecast to break down and shift westward over the next few days, and then "pendulum" back to the east coast by the middle of next week. Temperatures will remain elevated, but confidence in meeting advisory level criteria is lower beyond Saturday. Will therefore wait on extending the ongoing Heat Advisory beyond it currently planned Saturday expiration. But we may need to either extend it, or issue another one next week based. Otherwise, best rain chances over the coming days will be in the southern part of the CWA, largely due to the presence of a tropical wave along the Gulf coast.

AVIATION

(00Z TAFS) Issued at 652 PM CDT THU SEP 3 2026

The region will remain under the influence of the stout upper- level ridge, which will keep terminals in VFR category for most of this TAF period. Shower and thunderstorm coverage will increase tomorrow afternoon around MGM and AUO, but confidence was not high enough to introduce TSRA in any FM groups at this time.

Note: AMD NOT SKED continues for AUO due to a weather observation outage.

FIRE WEATHER

Minimum RH values will generally remain above 40% through the work week. Low (10 to 20%) chances for showers and storms will continue daily. Fire weather concerns are currently low, but decreasing soil moisture will begin to raise these concerns by next week given a lack of forecast rainfall.
