For the remainder of Tuesday, snow will blanket portions of the Plains and much of the upper Midwest. Meanwhile, rain will develop from the southern Plains into the mid-South.
By December 30-31, heavy rain from eastern Texas into the lower Ohio Valley could total 2 to 5 inches or more, possibly resulting in flooding. Meanwhile, severe thunderstorms may occur across the Deep South, especially in the western and central Gulf Coast States.
On New Year’s Eve and New Year’s Day, a second round of snow will develop, starting in west-central Texas and spreading across the east-central Plains and upper Midwest.
