USDA's Joint Ag Weather Facility says in the Corn Belt, the coldest weather of the season prevails. "This morning’s temperatures fell below 10°F in the upper Midwest," USDA adds. Snow has mostly ended across the eastern Corn Belt, USDA reports, except for lingering snow squalls downwind of the Great Lakes. "Current snow depths include an inch in Madison, Wisconsin; Fort Wayne, Indiana; and Dayton, Ohio," USDA elaborates.
In the West, USDA says mild, showery weather prevails in northern California and the Pacific Northwest. "Elsewhere, mild, dry weather continues to promote fieldwork, including cotton harvesting in California and Arizona," USDA adds.
On the Plains, USDA says cold conditions persist in most areas. "This morning’s temperatures fell to near 0°F in the eastern Dakotas," USDA details. However, mild conditions are quickly developing across the northern High Plains due to chinook (downslope) winds, USDA continues.
In the South, USDA reports warmth lingers across the southern Atlantic region, but sharply colder weather prevails elsewhere. "Dry weather continues to promote fieldwork, although short-term dryness is becoming a concern in much of the Southeast," USDA explains.
In its outlook, USDA says during the next couple of days, the coldest air of the season will settle across the South, East, and Midwest. "On Wednesday, for example, temperatures below 20°F will again occur in much of the Midwest, with a few readings below 10°F," USDA explains. Meanwhile, unusually warm weather will prevail in the West, USDA continues. "During the mid- to late-week period, cold air will quickly erode, leaving much of the U.S. with near- to above-normal temperatures," USDA reports. By week’s end, the temperature pattern will reverse, with warmth (and showers) across the eastern half of the U.S. and colder conditions farther west, USDA elaborates. Precipitation will also develop late in the week in the Northwest, it adds.
