The severe weather threat is not over.
The storms now over the middle of the state don’t have much to work with in the way of instability, but they are getting a little reinvigoration from the approaching low pressure system. They will produce heavy rain, gusty winds, lightning and hail as they continue eastward from their current orientation from Winston through Walker into Tuscaloosa Counties. They will affect the Birmingham metro area between 8 and 9 as they move ENE at 25 mph.
To the west, closer to the lows, instability is a little greater thanks to colder temperatures aloft. In addition, wind shear is increasing ahead of the low. As a result, there will be a continued severe weather threat across Alabama until the disturbance and a cold front pass through later tonight. Large hail will be a significant threat, along with damaging winds and an isolated tornado is not out of the question.
Several counties in eastern Mississippi are under severe thunderstorm warnings.
A tornado watch is in effect for the northern two thirds of Alabama until 2 a.m.
