KEY MESSAGES

Issued at 1252 AM CDT THU AUG 6 2026

- Heat: Humidity will push heat indices into the 95-100 degree range Thursday and increase as we head into this weekend. For this weekend into the beginning of next week, heat indices will range from 96-104, resulting in a moderate heat risk across Central Alabama.

DISCUSSION

(Thursday through next Wednesday) Issued at 1105 PM CDT WED AUG 5 2026

This evening, the upper shortwave trough that dipped across the Southeast US should be absorbed back into the main upper trough across North Central and Northeast Conus by Thursday morning. After that Alabama will be in a benign weak area south of the main broad flat trough and in-between two ridges, one across the Four Corners and the other elongated extending eastward off of the VA/NC Coast with only minor perturbations traversing the weak flow across Central Alabama. This will result in typical summertime diurnally enhanced convection that will be mainly outflow driven. By Monday, the Western Atlantic ridge flattens and retrogrades westward across the Northern Gulf Coast. The only difference will be the slightly better rain chances before this will be in the eastern half. After this reorientation of the upper ridge, the northern areas may see a tad more effects from shortwave activity, but not by much.

As for temperatures, readings do climb up a small amount this weekend with overall moisture not changing much. This will result in max afternoon heat indices perhaps a few degrees higher in spots. However, at this time, guidance does not warrant a heat advisory just yet. Will be monitoring this over the next couple of days if that trend changes.
