KEY MESSAGES

Issued at 624 AM CDT SUN SEP 13 2026

- Persistent Heat: Afternoon high temperatures will continue to reach the low to middle 90s for much of the next week, with heat indices from the middle 90s to above 100 degrees. Take extra precautions with any extended afternoon outdoor activities.

DISCUSSION

(Sunday through next Saturday) Issued at 1056 PM CDT SAT SEP 12 2026

A few showers will linger over the next few hours before clearing as the trough exits the region. Meanwhile, upper-level ridging will quickly build in by Sunday, returning rain chances to a low- end, widely isolated, diurnally driven pattern. Latest CAMs show minimal rain chances in the far south on Sunday afternoon (15 to 20%), warranting a slight upward adjustment in PoPs.

Dry conditions will generally prevail on Monday, though a stray shower remains possible in the far northeast during peak heating. Confidence remains low regarding overall coverage, so PoPs will be kept at 10% for Monday afternoon as highs reach the mid to upper 90s. As the ridge continues to build through next week, rain chances will remain low (10 to 20%), with afternoon highs quickly rebounding into the low to mid-90s.

AVIATION

(12Z TAFS) Issued at 624 AM CDT SUN SEP 13 2026

IFR conditions at MGM with low vis and cigs will continue until around 13-14z, improving to VFR. Similar situation with AUO. During the afternoon hours, a low chance of showers across southern Central Alabama. Confidence is not high enough to include mention in MGM TAF. All sites should be VFR from 15z onwards.

AMD NOT SKED is appended at AUO due to missing observations.

FIRE WEATHER

Minimum RH values are expected to stay between 35-45% through next week, with very limited rain chances in the forecast past Monday. While fire weather concerns remain low for now, increasing drought conditions will push these concerns up by late next week if significant rainfall does not fall by then.
