As of Tuesday afternoon, the risk of severe thunderstorms is diminishing, though a few wind gusts above 40 mph are not out of the question, especially in northeastern Alabama.
The limiting factor today is the lack of high-energy, moisture-rich low-level air, and it likely plays a role in reducing the strength of storms.
The dewpoint likely stays at or below 59ºF as storms move into the Tennessee Valley region; we have no recorded tornadoes with dewpoints below 58ºF in the state of Alabama. So, we have enough fuel to get some storms going, but it’s not the kind of fuel that supports extreme storms. Approaching noon, the dewpoints are in the lower 50s across the Tennessee Valley.
The Bottom Line: Showers and storms have already passed through the Shoals area, and now scattered light rain showers are falling in the area. Further east, a line of heavy rain is pushing into Madison, Jackson and Morgan counties, and will make its way to Marshall, DeKalb, Etowah and Cherokee counties through 4pm. The storms have significantly weakened since passing through the Shoals area, and as of this writing, little to no lightning has been detected from these storms. With that in mind, heavy rain and gusty winds are the main impacts from this line of storms.
Further south, the storms will likely last longer in Central and South Alabama (as late as 9-10 PM between Montgomery and Dothan).
For voters going to the polls during your drive home, have Live Alert 19 on your phone so you can get lightning alerts and track the scattered showers to time out your trip to a polling site.
Polls are open until 7pm tonight. In Tennessee, Lincoln County polls are open until 7 p.m. Bring your photo ID!
You don’t have to take any action at all unless a watch or warning is issued for your county. Have Live Alert 19 on your device so you will know if/when something is posted for your location.
A “Watch” means we expect some strong/severe storms in a given time frame over a broad, multi-county area. A “Warning” means a severe storm is happening in a specific area.
We’ll keep you posted!
