A lifting frontal boundary will bring mixed precipitation from the central U.S. into the eastern states today through Tuesday.
Rain and a mix of snow and sleet are moving across the Ohio and Tennessee Valleys. Winter Weather Advisories are in effect from Indiana to Pennsylvania, where several inches of snow are possible, along with some sleet. Ice is also a concern in the Appalachians and Mid-Atlantic. Most areas could see light ice accumulations, but parts of the Virginia and West Virginia mountains may receive heavier icing. A Winter Storm Warning is in place for the higher elevations of West Virginia. Areas west of I-95 near Baltimore and Washington, D.C. could see 1–2 inches of snow late this morning into the afternoon, with a possible change to freezing rain Monday night.
A cold front in northern Texas will stall today, then lift north as a warm front on Tuesday. As warmer, unstable air moves into Oklahoma and Kansas, strong to possibly severe thunderstorms may develop. The main threat is large hail. Heavy rainfall is also possible from Missouri to Ohio, with 1–3 inches expected Tuesday into Wednesday. Flash flooding risk is low but cannot be ruled out.
Warmer temperatures will spread across most of the country this week. Highs in the South will reach the low to mid-80s. By Tuesday and Wednesday, temperatures in the Ohio and Tennessee Valleys may climb into the mid to upper 70s. The West will cool slightly as a trough and cold front move through, but temperatures will still remain slightly above average.
