Across the Corn Belt, a weak cold front stretches from Ohio to the Bootheel of Missouri. Snow showers are confined to the lower Great Lakes region, where corn harvesting and other late-season fieldwork activities remain largely on hold due to soggy soils.
On the Plains, patches of beneficial light rain are developing in Texas and southern Oklahoma, well in advance of an approaching storm system. Meanwhile, mild, breezy conditions are overspreading the northern Plains, accompanied by a few snow showers in Montana.
In the South, cool, dry weather is promoting late-autumn fieldwork, including winter wheat planting and cotton and soybean harvesting. Freeze warnings were in effect Friday morning in parts of northern Florida (well north of the citrus belt) and adjacent areas in Alabama and Georgia.
In the West, widespread precipitation (rain and high-elevation snow) in conjunction with a developing storm is falling across Arizona and southern portions of Utah and Nevada. In California, mild weather favors fieldwork, including harvest activities for various fruits and vegetables.
A storm system over the Southwest will drift northeastward, reaching the Great Lakes region by Sunday. A wave of low pressure will develop along the storm’s trailing cold front, enhancing and prolonging rainfall in parts of the South and East. During the next 5 days (through December 6), rainfall could reach 2 to 6 inches—with locally higher amounts—from eastern Texas into the Ohio Valley.
Meanwhile, the storm will also produce a stripe of heavy snow—mainly on Saturday—from the southern Rockies to Upper Michigan. Some of the heaviest snow can be expected from north-central Kansas into southeastern Nebraska.
Looking ahead, the 6- to 10-day outlook calls for colder-than-normal weather from the Pacific Coast to the Mississippi River, while near- to above-normal temperatures will prevail across the eastern one-third of the U.S. Meanwhile, wetter-than-normal conditions across the South, East, Great Lakes region, and parts of the northern Plains will contrast with near- to below-normal precipitation from the Pacific Coast to the central and southern Plains and the middle Mississippi Valley.
