NORTH AND NORTHWEST ALABAMA: For areas generally north I-20 and west of I-65 and across the Tennessee Valley: Precipitation started falling late Sunday evening but picked up after midnight, becoming heavy at times in spots. Some minor snow accumulations impacts may be possible early this morning in this area while surface temperatures are closest to freezing and precipitation is falling. Winter weather advisories are in effect until noon for Fayette, Lamar, Marion, Pickens, Tuscaloosa, Walker, and Winston Counties. There is a potential for up to 1″ closer to the MS state line with generally ~0.5″ or less elsewhere in the advisory area. Plan on slippery conditions during the early morning hours this morning.
The precipitation will then slowly transition to a rain-snow mix, then to mostly rain by Monday afternoon. Temperatures will slowly warm a few degrees through the morning hours and impacts will be lessened to completely diminished.
CENTRAL ALABAMA: For the area north of a Selma to Clanton to Wedowee line: A mixture of rain and snow mix will be possible from midnight until 9 am. After 9 am, all the precipitation that falls should mainly be rain. Little to no accumulation is expected. There could be a few slick spots on bridges and overpasses, so check road conditions before driving early this morning.
SOUTH CENTRAL ALABAMA: For areas to the south of this: The precipitation will fall as a cold rain and no impacts are anticipated.
