KEY MESSAGES

Issued at 612 AM CDT THU SEP 24 2026

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

DISCUSSION

(Thursday through next Wednesday) Issued at 1134 PM CDT WED SEP 23 2026

A few lingering showers are still ongoing in the far southeast this evening. These will fade over the next few hours as easterly flow increases across the area. This will result in some isentropic lift through mid-morning, possibly lasting until noon. Numerical guidance is very pessimistic regarding rain chances just before dawn and through noon; however, model graphics show enough consensus to warrant a low confidence in light rain moving east to west through the morning. Most locations may only see a trace, but a few could see minor accumulations. Even if it is only a light drizzle, it will give the perception of light rain falling. After noon, drier air works in from the east, starting another dry spell, this time about 15 degrees cooler than the recent heat wave. Highs will be in the upper 70s to low 80s through the rest of the week and into the weekend, making for pleasant outdoor conditions.
