KEY MESSAGES

Issued at 724 PM CDT TUE MAY 26 2026

- A Flood Watch is in effect for much of Central Alabama through this evening.

- Additional periods of scattered to numerous showers and thunderstorms are forecast through the week, with low to medium chances for isolated flash flooding or a strong thunderstorm.

DISCUSSION

(This afternoon through Monday) Issued at 1152 AM CDT TUE MAY 26 2026

A persistent rainy pattern is expected to continue through the remainder of the week and into the weekend. A strong cut-off upper low located in the vicinity of the Great Basin effectively blocks the synoptic pattern for much of the week. This will lead to status quo for our area with troughing just to our west and ridging to our east pulling in ample deep layer moisture from the Gulf. Predictability is low on the location of the rain and thunderstorms each day due to the weak surface forcing; however, overall coverage of showers and storms will mean that generally over 60-70% of locations will see rain each day with the highest coverage during the afternoons.

With the humid air mass in place, fog and/or low clouds can be expected overnight each night in areas that see the heaviest rainfall the previous day.

As we see several days of rainfall over the same locations, there's increasing chances for isolated flooding concerns as the soils become saturated, and therefore we could see quicker rises on area creeks and streams.

AVIATION

(00Z TAFS) Issued at 720 PM CDT TUE MAY 26 2026

Current VFR conditions are expected to deteriorate between 4-8z across Central Alabama as we remain in a wet onshore flow pattern There is a low to moderate chance for SHRA/TSRA at MGM/AUO this evening/tonight with a rain "break" for the rest. Cigs are expected to lower further to IFR/LIFR after 8z and continue through sunrise. Cigs will then slowly rise back to VFR by 17- 18z. More diurnally enhanced convection is expected across the area TAF sites again on Wednesday after 15z as no changes in the overall pattern are expected in the short term.
