USDA's Joint Ag Weather Facility says on the Plains, temperatures have already begun to rebound from Monday’s bitter cold. "An upper-air disturbance is generating snow in northern portions of the region, while drought continues to afflict southern Plains’ winter wheat areas," USDA details.
In the West, USDA reports warmer- and drier-than-normal weather continues to raise concerns for developing drought from California into the Great Basin. "Mountain snowpacks (snow water equivalent) in the Sierra Nevada are averaging less than 50% of normal, while some areas in the Cascades are less than 10% of normal," USDA elaborates.
In the Corn Belt, cold, mostly dry weather prevails, USDA reports. "A fresh snowpack insulates winter wheat in northern and western portions of the region, while recent warmth and rain melted the snow cover in the Ohio Valley," USDA explains.
In the South, USDA says drier weather has returned following yesterday’s soaking rainfall in the Southeast, promoting a return to fieldwork. "Most of the region benefited from the recent rain, which eased short-term dryness along the central Gulf Coast and from Georgia into the Carolinas," USDA details.
In its outlook, USDA says high pressure will maintain dry weather across much of the nation through the end of the week. "However, an upper-air disturbance will generate light to moderate snow as it treks from the northern Plains into the Great Lakes and Northeast," USDA reports. Snow could fall as far south as the northern Ohio Valley on Christmas Day, but otherwise dry weather will prevail across the lower 48 states for the mid-week holiday, according to USDA.
