KEY MESSAGES

Issued at 609 AM CDT FRI SEP 4 2026

- Significant Heat Risk: Heat indices will remain between 105-108 degrees through the weekend. The Heat Advisory is now in effect until 8 PM Sunday.

DISCUSSION

(Friday through next Thursday) Issued at 1145 PM CDT THU SEP 3 2026

Stout upper-level ridging will remain in the driver's seat for the majority of this forecast period, with no real end in sight. There will be some slight relief this weekend, as the apex of the ridge breaks down and shifts west, allowing a disturbance along the Gulf to slide north. Unfortunately, this relief is limited, with the best rain chances this weekend remaining along the I- 85 corridor. Isolated and scattered rain chances will also remain in the forecast through the middle of the week, with the center of the ridge remaining over the central Plains, but widespread rainfall is not expected.

By the middle of next week, a deep trough will begin to take shape over the west coast, shifting the ridge right back over top of us. High temperatures will quickly rebound, climbing right back into the mid and upper-90s. However, given some uncertainty in afternoon dewpoint values, confidence in the need for additional heat headlines during this time is low. Regardless, it does appear that the heat is here to stay.

AVIATION

(12Z TAFS) Issued at 609 AM CDT FRI SEP 4 2026

Prevailing VFR conditions are expected for all sites through most or all of the TAF period with easterly winds less than 8 knots. However, low clouds and/or fog could impact KMGM and KAUO with IFR conditions at the very end of the TAF period. Very isolated showers and thunderstorms could also affect some sites, but confidence is too low for a PROB30.

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.
