USDA's Joint Ag Weather Facility says 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," USDA says.
In the West, USDA reports 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," USDA adds.
In the Corn Belt, USDA says 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," USDA explains.
In the South, cool, dry weather is promoting late-autumn fieldwork, including winter wheat planting and cotton and soybean harvesting, according to USDA. "Freeze warnings are in effect this morning in parts of northern Florida (well north of the citrus belt) and adjacent areas in Alabama and Georgia," USDA adds.
USDA's outlook says 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," USDA reports. During the next five days (through Dec. 6), rainfall could reach 2 to 6 inches—with locally higher amounts—from eastern Texas into the Ohio Valley, according to USDA. "Meanwhile, the storm will also produce a stripe of heavy snow—mainly on Saturday—from the southern Rockies to Upper Michigan," USDA says. Some of the heaviest snow can be expected from north-central Kansas into southeastern Nebraska, according to USDA.
