USDA's Joint Ag Weather Facility says in the Corn Belt, showers and thunderstorms will develop throughout the day across the Midwest, with precipitation falling as snow in the colder northern areas.
In the West, USDA says winter weather advisories are in effect throughout the Pacific Northwest and Rocky Mountain states, with locally heavy accumulations of rain and snow hampering transportation throughout the day. "In contrast, drier albeit cooler weather dominates much of California," USDA explains.
On the Plains, USDA says a wintery mix of precipitation is spreading into northern portions of the region, with several inches of new snow expected locally in the Dakotas and Minnesota. "Warmer conditions continue on the southern Plains, with daytime highs approaching 70°F in some locations," USDA adds.
In the South, USDA reports scattered, generally light showers extend from the Delta to the mid-Atlantic Region, with icy conditions hampering travel from Virginia northward.
In its outlook, USDA says frozen precipitation will gradually end in the mid-Atlantic Region, but a new storm is forming in the nation’s mid-section, which promises to bring locally heavy precipitation to much of the East over the next few days. "Accumulations in excess of 2 inches are possible from the Mississippi Valley into New England, and strong storms are anticipated for the Southeast," USDA adds. Meanwhile, USDA says cold, mostly dry weather is developing on the Great Plains. "By Wednesday, temperatures are forecast to fall well below 0°F in northern areas, where a shallow snow cover offers some protection to overwintering grains and pastures," according to USDA. Snow showers are expected to linger through week’s end throughout much of the West, although amounts and coverage will diminish over time, USDA explains.
