Good Friday afternoon! Here’s an update as of 1:15pm… The map above shows where I expect what type of accumulation and precip type this afternoon and into tonight. It sure looks like there will be a sweet spot somewhere near I-20, where a wintry mix could transition to snow later this afternoon, evening and into tonight. If this indeed occurs, anyone near the I-20 corridor could see anywhere from a dusting upwards of 4″ of snow.
A winter storm warning has been added to include most of central Alabama including Pickens, Tuscaloosa, Jefferson, Sumter, Greene, Hale, Perry, Marengo, Bibb, Chilton, Shelby, Coosa, Talladega, St. Clair, Etowah, Calhoun, Clay and Cherokee County in our coverage area. In this zone, a mix of freezing rain, sleet and snow will accumulate and cause travel hazards through the afternoon and into the overnight hours. Conditions in this zone will deteriorate from here on out, so avoid travel if possible. By sunset this evening, I expect major travel issues, as temperatures drop well below freezing across all of west and central Alabama, especially where wintry weather is the most intense. North of the winter storm warning is a winter weather advisory, where minor snow accumulations are possible and some roads hazards as well. This includes Lamar, Fayette, Walker, Blount, Cullman, Winston and Marion County through tonight.
The band of wintry weather continues to organize to our west and will fill into the area for the rest of the afternoon. The sweet spot for snow and sleet accumulations looks to be close to the I-20 corridor later this afternoon and into tonight, as colder air aloft transitions the precip over to mostly snow. Areas near Tuscaloosa, Birmingham and Anniston could pick up 1 to 4 inches of snow, with someone getting more than that. Other spots may not get much snow at all. A swath of heavier precip will spread northward this afternoon and evening, and as colder air aloft arrives as well, that should help to develop a heavier axis of snow somewhere near the zone mentioned above.
Areas near the US HWY 80 corridor around York, Demopolis, Selma, Linden and Marion, this even will begin as freezing rain and sleet, then transition over to a mix of sleet and snow before ending this evening. Travel hazards will become significant, especially under the heavier precip and especially as temperatures fall this evening. Snow accumulations of 1 to 2 inches can’t be ruled out as far south as HWY 80, but the main concern is for freezing rain and sleet, which will cause problems through the afternoon.
All of the precip will come to an end late tonight from west to east. By sunrise tomorrow morning, all precip will be long gone.
