Valleywx.com: A Deep South Snow Event

Throughout this period of cold, dry weather we have talked about the “pattern” being favorable for snow. Well, it looks like it is finally going to produce it…south of us.

That’s not to say the Tennessee Valley region has zero chance of snow; we will see some light snow flurries and showers, and a few spots might even get enough for a light coating of white from Tuesday morning into the early afternoon. This is the specific chance of at least one inch of snow from NOAA’s WPC:

Specifically, I would expect a little better chance of a dusting than some of those numbers represent on top of Brindlee, Sand, and especially Lookout Mountain in Etowah and DeKalb Counties.

Here are the model plots from the European and Canadian models showing the heaviest stripe of snow through South Alabama and Georgia. Cities like Mobile and Montgomery have a good chance at getting more than 1 to 3 inches of snow between Tuesday afternoon and Wednesday morning:

This is the general idea right now, so if you’ve got travel plans south of the Tennessee Valley, expect to run into some issues (especially south of I-20) starting around 10 AM to Noon on Tuesday:

We do not expect significant travel problems due to snow or icy roads north of I-20; however, a few slick spots may develop where heavier snow showers exist mainly in the higher terrain above 1000′ on Lookout Mountain and the terrain south of there toward Talladega and Anniston.

It’s definitely going to be cold whether you get any snow or not! Expect the wind chill to be in the single digits and teens with a cloudy sky on Tuesday. See the main forecast discussion at WHNT.com/Weather for the specifics on the cold and when to finally expect a prolonged warm-up!
