KEY MESSAGES

Issued at 604 AM CDT FRI AUG 7 2026

- Heat: Humidity will push heat indices into the 97-104 degree range this weekend into next week, resulting in a moderate heat risk across Central Alabama.

DISCUSSION

(Friday through next Thursday) Issued at 1146 PM CDT THU AUG 6 2026

This evening, Central Alabama remains in a weak upper flow area south of the main broad trough that extends out of a Central Canada low and down into the Mid MS River Valley. At the same time, Alabama is situated between two ridges, one across the Four Corners and the other in the Western Atlantic off of the VA/NC Coast with only minor perturbations traversing the weak flow across Central Alabama. This has resulted in typical summertime diurnally enhanced convection, but that is also at times outflow driven. By Monday, the Western Atlantic ridge flattens and retrogrades westward across the Northern Gulf Coast. The only difference for Monday onward will be that of a slightly different orientation of the better rain chances from shortwave activity, but it would still be diurnally enhanced.

As for temperatures, readings do vary a degree or so here and there over the next week with overall moisture remaining up. This will result in max afternoon heat indices perhaps a couple of degrees higher in spots. However, guidance continues to keep us below heat advisory criteria for now.
