An amazing boundary remains positioned across North Alabama tonight in a west/northwest to east/southeast orientation.
It is being fed by strong southerly inflow.
The main activity has now shifted back to Northwest Alabama and western Tennessee.
The storms over eastern Alabama have weakened and shifted into western Georgia.
Storms have become more widespread over Lauderdale and Colbert Counties, through Lawrence into Morgan and Madison County. They extend back into Limestone and northern Madison Counties.
The strongest cell was west of Flint City and Hartselle. A new severe thunderstorm warning was just issued for Morgan county.
A severe storm is over southern Tennessee, passing south of Selmer or north of Corinth, MS. This storm will move eastward along the Tennessee/Mississippi border, perhaps affecting the Northwest corner of Alabama later.
Some impressive rainfall amounts today across the Tennessee Valley. The main axis was along the Tennessee River down into Marshall, Cullman and Blount Counties. Also over into southern Dekalb into southern Cherokee and Etowah Counties.
Rainfall amounts in these areas likely were in the 2-3 inch range with a few locally higher amounts.
Flash flood warnings have expired for several counties in the Tennessee Valley, but I expect they will be reissued later as the heavy rain expands.
