The storms over the Tennessee Valley tonight are sinking southward tonight.
They extend generally along and north of AL-157 from Moulton to Eva to northwest of Guntersville.
The storms over Northwest Alabama have weakened and laid down an outflow boundary into Franklin and Marion Counties. This may be a factor in storm development tomorrow.
Some cells were forming along the outflow down into Winston County. But I don’t think the atmosphere will sustain the storms as we continue to move away from the heating of the day. I could be surprised.
Further east, through southern Lawrence into southern Morgan and southern Madison Counties are sinking southward. Folks in Cullman and Marshall and eventually Blount and Etowah Counties will see more heavy rain and lightning again.
Let’s be alert for flooding overnight, since parts of this area have received some impressive rainfall amounts today. Flash flood warnings have just been reissued.
I think the rain and storms will stay north of the Birmingham metro area overnight, but don’t be surprised if the boundary sinks a little further south than I think.
