A winter storm system continues to wreak havoc from the Central Plains to the Ohio River Valley. On the northern side of the system, the precipitation type has been all snow. Where there is warm air aloft and cold air at the surface, a mixture of sleet and freezing rain has been falling from Missouri to Kentucky. Earlier this morning, I even saw reports of thunder sleet in the Ozarks.
Ahead of the system, the air is warm and the precipitation type is all rain. We are in the warm sector, ahead of the approaching cold front where temperatures are already in the 60's. Temperatures this afternoon are going to climb into the 70's and even to near 80° to the southwest of Tuscaloosa. We are not expecting record breaking temperatures but they will be averaging some 10-15° above normal.
Overnight, the winter storm to the north creeps closer and will send rain and storms our way from west to east. The chance increases especially after midnight. We are not expecting severe storms, just general thunderstorms. The risk for severe storms is across Louisiana and eastern Texas.
As colder air noses is at lower levels, it will cause rain to freeze on contact. This threat will set up across northwest Alabama. A winter weather advisory has been issued by the Huntsville National Weather Service and is effective from 12AM until 9AM Monday. Lauderdale, Limestone, Colbert, Lawrence and Franklin counties are under the advisory. A tenth(.10") to two tenths (.20") of freezing rain is possible. The glaze will be confined to elevated surfaces, like bridges, overpasses, cars and trees but most roadways will be wet because ground temperatures are so warm. The best chance for precipitation is between midnight and 11AM Monday before the system exits eastward. The air behind the cold front is going to drop quickly. Highs on Monday will occur at midnight and then fall into the 30's by late morning hours and struggle to rise back into the 40's during the afternoon hours. Even with afternoon readings in the 40's, blustery winds from the north will make it feel like it's in the 30's. So don't put away the winter coat just yet because you'll need it on Monday and certainly by Tuesday morning when the air cools into the 20's.
