Alabama 811 | Know What's Below.

Midday Update

| April 10, 2013 @ 12:56 pm

After a review of the 12Z model data… looks like we will need to hit the tornado threat a little harder for tomorrow, especially over the eastern two-thirds of Alabama…

Below is the 4km (high resolution) NAM output valid at 4 p.m. tomorrow…

Note the potential for discrete cells ahead of the main squall line. These storms will have the potential for a few tornadoes based on the new projected wind profiles.

I will have a full discussion and Weather Xtreme video by 4:00… but here are the important points…

*All modes of severe weather will be possible across Alabama tomorrow… below is a graphic prepared at midday by the NWS Birmingham

*SPC has raised a 45 percent probability of severe weather for parts of Alabama tomorrow afternoon… meaning a “moderate risk” will be needed… highest severe weather probabilities are south of I-20, and east of I-65.

*Storms should impact places in West Alabama like Haleyville, Vernon, Fayette, Hamilton, Jasper, Tuscaloosa, Eutaw, and Greensboro from 11:00 a.m. until 3:00 p.m.

Then, the risk moves east, and from 3:00 until 6:00 p.m. cities like Birmingham, Cullman, Brent, Oneonta, Cullman, Clanton, and Pell City.

And, the biggest risk from 6:00 until 9:00 p.m. will be for communities like Anniston, Gadsden, Ashland, Centre, Heflin, and Roanoke, in East Alabama.

Again… look for a detailed update a little later this afternoon along with a fresh Weather Xtreme video…
