Good Thursday afternoon! The National Weather Service just triggered a large portion of Alabama in either a winter weather advisory or a a winter storm warning for Friday into Friday night.
Counties in pink are under a winter storm warning include Calhoun, Cleburne, Shelby, Talladega, Clay, Randolph, Chilton, Coosa, Tallapoosa and Chambers Co in east central Alabama. In that zone roughly to the south of I-20 and to the est of I-65, snow and sleet accumulations of 2 to 3 inches are possible beginning as early as Friday morning and lasting through sunrise Saturday morning. That is for the counties listed above…
Areas in purple across west, central and north Alabama are under a winter weather advisory for Walker, Marion, Lamar, Fayette, Cullman, Blount, Etowah, Cherokee, Pickens, Jefferson, Tuscaloosa, St. Clair, Bibb, Sumter, Greene, Hale, Perry, Marengo Counties.
Areas along and to the north of I-20, this appears to be mostly a light snow event, as temperatures above the surface support all snow. To the south of I-20, a wintry mix of freezing rain, sleet and snow is possible beginning Friday morning and lasting through late Friday night. The event may end as light snow as far south as the HWY 80 corridor, where some minor snow accumulations are not out of the question.
Moisture and uplift will be key to whether there are actually snow accumulations in our area or not. Just because you are under an advisory or winter storm warning does not guarantee you will get accumulating snow at your house. This is an incredibly complicated setup, and some model data suggest much of central Alabama will get little to NO wintry precip. If indeed those computer models are correct, this would turn out to be a little to no impact event, with cold air being the big story. If the model data that suggests our area will deal with wintry precipitation is correct, travel issues would become a concern during the day on Friday and into Friday night.
Please keep checking back with us for updates as things could easily change. Forecasting winter weather in Alabama is incredibly challenging and this event is especially challenging.
