Alabama at 6 O’Clock

A few showers are moving eastward across North Central Alabama early this evening. They are over Walker and western Jefferson Counties, moving toward southern Cullman, Blount and eventually St. Clair Counties.

The rain is light and won’t last long.

Showers have exited East Alabama into Carroll County, Georgia.

Looking west from the vantage point of the Columbus radar…showers over Itawamba County MS are part of a broken line of showers and storms that extends into South Mississippi. Heavier showers and storms will affect Sumter and perhaps Green Counties over the next 2-3 hours. This activity is heading east right now, but storms further to the west around Carthage and Philadelphia are moving east northeast. If a more east northeast trend continues, later storms could edge further northward into North Central Alabama, and they could be heavy.

There is a pronounced instability axis over South and Central Mississippi with CAPE values pushing 2000-3000 j/kg thanks to temperatures in the lower 80s and dewpoints in the upper 70s.

Instabilities are not as high over Alabama, with CAPE values greater than 1000 j/kg from Lamar and Pickens Counties southeastward to the Montgomery area. The dewpoint at BHM is up to 70F, and 72F at Tuscaloosa but with no sun today, temperatures never got out of the 70s. It will be interesting to see if the more unstable airmass over Mississippi is able to advect eastward into Alabama, and it looks like it might. This which would make the potential for strong to borderline severe storms later much greater.

Radar composites show a line of showers back over western Tennessee and northwestern Mississippi ahead of a cold front that now extends from southeastern Missouri into Central Arkansas. This front is expected to be near Birmingham by morning and then move to South Alabama by tomorrow night.

Nice weather Thursday, the increasing rain chances Friday with storms likely Friday night, ending Saturday morning, followed by a nice week next week.
