KEY MESSAGES

Issued at 109 AM CDT WED SEP 23 2026

- Severe Weather: A few strong to severe storms will be possible in the northeast by the afternoon. The primary threat will be damaging winds gusts up to 60 mph.

- Cooler, Drier Early Fall Pattern: A noticeably cooler and drier air mass settles across Central AL for Thursday evening through the weekend, bringing daytime highs in the lower-to-middle 80s and nighttime lows in the 50s and 60s.

DISCUSSION

(Wednesday through next Tuesday) Issued at 1137 PM CDT TUE SEP 22 2026

As a cold front slowly moves through the region into Wednesday, shower and thunderstorm activity will gradually taper off from northwest to southeast. A few stronger storms remain possible across the northeast through Wednesday afternoon as the front progresses. A deepening trough will develop to our east Wednesday through the weekend while a ridge builds to our west. Until the ridge becomes firmly established, isolated showers may persist along the front in western areas through early Thursday afternoon.

Following several weeks of above-normal temperatures, a welcome transition to fall-like conditions is expected. Daytime highs will range from the low to mid-80s across much of the area, with upper 70s limited to far eastern portions of Central Alabama. Overnight lows will drop into the mid-to-upper 50s across northern sections, with lower-to-middle 60s further south. This dry, seasonable regime will persist through the upcoming weekend and into early next week, bringing tranquil conditions and little to no rain potential across all of Central Alabama.

AVIATION

(06Z TAFS) Issued at 109 AM CDT WED SEP 23 2026

Low clouds remain possible overnight, but confidence was not high enough to introduce any additional FM groups outside of AUO. Shower and thunderstorm chances return again past 23/18z, but confidence in coverage remains low as well, so I did not introduce any TSRA with this forecast. Otherwise, VFR conditions are anticipated for the remainder of this TAF period.

Scattered thunderstorms are expected this afternoon, followed by drier conditions arriving Thursday evening and continuing through the weekend. Minimum relative humidity (MinRH) values will remain between 40% and 60% through the end of the week. However, drier air will build in over the weekend, with MinRHs approaching critical thresholds on Saturday and Sunday. Winds are expected to remain generally light and easterly.
