USDA's Joint Ag Weather Facility says in the Corn Belt, snow disruptive to travel but beneficial for winter wheat is primarily confined to the Ohio Valley, although a few snow showers and flurries are occurring in the Great Lakes region. "Current snow depths include 2 inches in Indianapolis, Indiana, and St. Louis, Missouri," USDA details.
In the West, USDA says some snow is falling in the northern Rockies, while rain and snow showers dot the northern Intermountain region. "Dry weather prevails in California, although a Pacific storm is approaching," USDA adds.
On the Plains, USDA reports a variable, mostly shallow snow cover continues to provide winter wheat with beneficial moisture and insulation across the northern half of the region.
In the South, USDA says cold air has pushed deeper into Florida, but sub-freezing temperatures remain north of the primary citrus, strawberry, and winter vegetable production areas. "Meanwhile, wintry precipitation (mostly snow and freezing rain) is causing some travel disruptions in parts of Kentucky, Tennessee, and environs," USDA adds.
In its outlook, USDA says for today, a weak but disruptive storm system will traverse the eastern one-third of the U.S. "Wintry precipitation, mostly snow and freezing rain, will spread across the Ohio Valley and the interior Southeast, leading to possible travel disruptions," USDA elaborates. Meanwhile, it says a stronger storm currently crossing the Intermountain West will closely trail the first system. "By late Thursday, the second storm will reach the lower Mississippi Valley," USDA details. From Jan. 22-24, potentially record-setting accumulations of wind-driven snow will affect portions of the Mid-Atlantic and Northeastern states, with totals of 1 to 2 feet or more possible in some areas, according to USDA. Meanwhile, the department says freezing rain could cause significant icing problems in parts of Kentucky and the southern Mid-Atlantic region. "In most areas of the U.S., a period of mild, tranquil weather will trail the powerful storm," USDA explains. However, stormy weather will return to the northern two-thirds of the western U.S., with five-day totals reaching 2 to 4 inches in northern California and the Pacific Northwest, according to USDA.
