Some Big Storms / Bye Bye Bonnie

A line of fairly big storms is positioned from southwest to northeast across Central Alabama this afternoon. It is actually likely a feeder band from the now defunct tropical depression Bonnie. Really more like a convergence zoneout ahead of the northwestward moving disturbance.

It extends from Choctaw and Marengo Counties into Ha;e and Perry Counties then into Bibb, Chilton and Shelby Counties and on across Talladega and Calhoun Counties.

Some of the heaviest storms were in northern Shelby County approaching Inverness from the south…and near Ohatchee in Calhoun County.

Other heavy ones extended across eastern Bibb and Shelby Counties from West Blocton to Montevallo over to Meadowbrook…with still more south of Tuscaloosa.

From a reader:
Hi Bill:
It has been heavy rain and periods of thunder here in Montevallo since about 3: o clock. Coming from that band out of Bibb
Thanks
Dowvan Perry

Skywatchers Alston Keith and John Talbot hearing thunder in Inverness and Hueytown. Nathan Jones in Pelham says: “.23″ of rain so far with house shaking thunder. Temp at 80.9. Nice break to say the least.”

Be alert for very heavy rain from the stronger, slow moving storms. There is lots of deadly lightning as well. We could also see some damaging winds from any collapsing storms.

So far, the high temperature from observations at the BHM Airport has been 97F.

The NHC has issued the last advisory on Bonnie. The system has weakened into a remnant low pressure system that will come ashore on the Louisiana Coast tonight.
