MONTGOMERY, AL (WSFA) - A deep, dynamic storm system will plow into Alabama late Friday into Saturday, bringing a risk of wind damage, large hail and perhaps a tornado or two to the state.
We expect a cluster of thunderstorms to form over parts of Tennessee, Missouri and Kentucky late Friday, then surge southward Friday evening. This batch of storms should move into north Alabama late Friday, then push into the central and southern sections of the state Friday night into Saturday morning.
The initial band of storms will slowly diminish as they move southward. But, more storms could fire up Saturday afternoon, and some of those could be intense, too. The main threat with that round of storms will be large hail, and that will tend to favor the southern counties of Alabama.
We expect the most intense storm cores to be fully capable of producing damaging wind and some large hail. And, while the risk is greatest in the northern counties of Alabama, I believe these storms will still be potent when they reach the central sections of the state. So, the threat is greatest in our northern counties and a bit lower south and west.
There is a TON of instability, the question is shear - is there enough to sustain thunderstorm updrafts? Is there enough to spin up a couple of tornadoes? Those are questions that we won't be able to answer until the small scale details become more apparent.
The deep upper trough hangs around through much of next week, meaning temperatures should stay near or below normal, with rain chances lingering through most of the next 7 days.
