KEY MESSAGES

Issued at 621 AM CDT WED AUG 26 2026

- Storms: Rain chances increase from mid to late this week with periodic showers and thunderstorms becoming scattered Wednesday and potentially more widespread Thursday and Friday.

DISCUSSION

(Wednesday through next Tuesday) Issued at 1138 PM CDT TUE AUG 25 2026

Surface observations and earlier visible satellite imagery indicated a few areas of surface boundaries and convergence across the area. While the weather pattern and nighttime stability will promote fair-weather conditions overall, some high-res guidance show the potential for a very sparse occurrence of short-lived showers tonight, likely associated with these features; nothing significant, just a don't-be-surprised mention.

From Wednesday through Friday, a weakness in the 500 mb ridge will exist thanks to longwave troughing near the Great Lakes region. This setup will allow for several mid-level impulses to meander across Alabama and its vicinity. Associated lift and an increase in dew points/moisture will promote periods of showers and thunderstorms, especially from afternoon to evening. Ensemble data continue to suggest scattered coverage on Wednesday, followed by potentially more widespread activity on Thursday and Friday as a surface front approaches from the north. Shower and thunderstorm coverage during the weekend seems to decrease as 500 mb ridging becomes a bit more defined.

No temperature extremes are noted through the forecast period, featuring seasonal highs and lows alongside mugginess.

AVIATION

(12Z TAFS) Issued at 621 AM CDT WED AUG 26 2026

Confidence remains high in afternoon showers and thunderstorms increasing in coverage. As such, I have maintained TEMPO groups at TCL, BHM, EET for TSRA, and PROB30 groups at MGM and AUO for TSRA as well. Outside of the afternoon thunderstorms, VFR conditions will prevail for most of this upcoming TAF period.

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