Update on Tuesday snowfall potential

From James Spann:Here are the highlights of what to expect tomorrow

ALL of Alabama will be very cold. The northern quarter of the state, north of U.S. 278, won't get out of the 20s. The high for Birmingham, Tuscaloosa, Anniston, and Gadsden will be only in the low to mid 30s.

Snow will begin Tuesday morning over North Alabama, but it will be light. There is a good chance you will see snow in Birmingham, Tuscaloosa, Anniston, and Gadsden, but it should be light, and significant accumulation is not expected. No major travel issues are expected in these areas despite the snow.

The chance of accumulating snow begins generally along and south of a line from Livingston to Eutaw to Greensboro to Centreville to Alabaster to Talladega to Ranburne. Some light accumulation is possible (1 inch of less) in the counties under a Winter Weather Advisory. These counties are Sumter, Greene, Hale, Bibb, Shelby, Talladega, Clay, Randolph, Perry, Chilton, and Coosa. Some minor travel issues are possible, if you live or travel in these counties, we don't expect widespread road problems, but icy spots are very possible.

The major snow/ice threat is along and south of U.S. 80, or south of a line from Demopolis to Selma to Montgomery to Opelika. Some communities over South Alabama could see 2 to 4 inches of snow. The heavier snow will come across South Alabama from around 12:00 noon Tuesday through 10:00 p.m.

Near the coast, the precipitation will begin in places like Mobile, Gulf Shores, and Pensacola as rain and sleet. This will change to freezing rain Tuesday evening, and snow Tuesday night. Mobile and Pensacola could see around one inch of snow, but freezing rain and ice is the bigger threat for these coastal cities.

Travel will be greatly impacted across the southern half of Alabama. Bridges and overpasses will be icy and dangerous, and some black top roads will become slick as well where heavier snow falls. The I-10 Bayway between Mobile and Spanish Fort will become very icy Tuesday night.
