We've been tossing around the possibility of severe storms Tuesday for about a week now. Now - it appears the forecast will be a reality. I think I have enough data to help you plan your day tomorrow around the severe weather. First of all, this system is higher impact than the one last Wednesday. We have two main threats. The first is the chance for tornado-producing supercells ahead of the squall line and the other threat includes the likelihood for dangerous high winds. (I'm taking the patio umbrella down after I do this post).
Let's get specific with times and impact. The Storm Prediction Center will likely issue a tornado watch late Tuesday morning.
2-4pm: Storms beginning to impact West Alabama. Discrete supercells may be firing ahead of the main line. The storms that are by themsvles are the primary tornado threats. This includes Tuscaloosa, Hamilton, Fayette, Jasper and nearby areas.
4-7pm: Storms crossing I-65. Winds over 58mph possible with the line of storms. Heavy rain as well. We could see imbedded rotating supercell thunderstorms. Storms will move through Birmingham, Hoover, as well as Shelby County.
7-9pm: Storms moving into East Alabama. This is the main line. Storms will weaken some after sunset, but still a dangerous line. Pell City, Anniston, and Gadsden impacted the most.
Again - these are projected times....a few supercells could pop in East Alabama well before the 7-9pm timeframe. Please stay weather aware.
After midnight - expect a few lingering showers and lower visibility. Weather looks good for Wednesday, Thanksgiving, and Friday. We'll see sunshine and cooler temperatures in the 60s.
