USDA's Joint Ag Weather Facility says on the Plains, a few light rain showers are developing across the southern half of the region. "Recent and ongoing precipitation has benefited the Southern Plains' winter wheat and has begun to revive drought-devastated pastures and rangeland," USDA reports.
In the West, USDA says rain and snow showers stretch from southern California into the Four Corners states. "Arizona's cotton harvest was 75% complete by Dec. 11, compared to the five-year average of 84%," USDA explains. Meanwhile, cool, dry weather prevails in the Northwest, according to USDA.
In the Corn Belt, rain is quickly overspreading the mid-Mississippi and lower Ohio Valleys, USDA reports. "Fieldwork remains largely on hold in the still-soggy eastern Corn Belt, where Ohio's corn harvest was 82% complete on Dec. 11," USDA explains. Many producers are waiting for fields to freeze before resuming the corn harvest, USDA says.
In the South, USDA explains a return to mild, dry weather favors late-season fieldwork. "In North Carolina, 89% of the soybeans had been harvested by Dec. 11, compared to the five-year average of 80%," USDA says.
According to USDA's outlook, warm air will surge northward in advance of a storm system emerging from the Southwest. "Snow will end later today in the Southwest, but mid-week rain (as much as 1 to 2 inches) will precede and accompany the storm across the central and southern Plains and the Midwest," USDA reports. By Thursday, the storm’s cold front will stretch from the Great Lakes States to the western Gulf Coast region, according to the USDA. "The tail of the front will stall across the South, where residual showers will linger through week’s end," USDA adds. Elsewhere, some rain and snow showers will develop in the Pacific Northwest, but mostly dry weather will prevail from California to the Northern Plains, USDA says.
