A front in the Southern Plains was expected to move eastward on Tuesday as a second system develops over the Plains and moves northeast. Widely scattered showers and thunderstorms were expected from the Great Lakes to the Deep South as a result.
This combined system was expected to spawn severe thunderstorms packing damaging winds in parts of the Mississippi, Ohio and Tennessee
valleys. Light to moderate snow was anticipated in the central Plains and upper Mississippi Valley.
Unusually warm conditions were expected across the southern and eastern U.S., with afternoon temperatures expected in the 70s and 80s in the Gulf States, while the Mid-Atlantic and Northeast were expected to be in the 50s and 60s.
Far chillier temperatures were expected in the Plains on Tuesday, where temperatures could plunge as much as 20 degrees in parts.
More cold, wet weather was in store for the West, where a storm system was expected to bring widespread precipitation, with the heaviest over western Oregon and northern and central California. Up to a foot of snow was possible above 1,500 feet.
Temperatures in the Lower 48 states Monday ranged from a low of minus 28 degrees at Boulder, Wyo., to a high of 90 degrees at Hebbronville, Texas.
