Bitter cold air covers the northern Plains, upper Midwest
On the Plains, cold, dry weather prevails. Monday morning’s low temperatures remained mostly above 0°F in the northern High Plains’ winter wheat belt, but dipped below -10°F in parts of western North Dakota.
Across the Corn Belt, colder air is settling across the upper Midwest, while mild weather prevails in the Ohio Valley. A shallow snow cover exists across much of the northern Corn Belt, where depths include 4 inches in Sioux Falls, South Dakota, and 3 inches in Lansing, Michigan.
In the South, drought-easing rain showers are spreading across the lower Southeast, although the southern-half of Florida’s peninsula remains extremely dry. Elsewhere, mild, dry weather favors early-season fieldwork.
In the West, patchy rain and snow showers are mostly confined to the Pacific Coast States. High-elevation snow packs remain significantly below average for late February in California, Oregon, Nevada, Utah, Arizona, western Colorado, and central and southern Idaho.
For the remainder of Monday, rain showers will affect the lower Southeast, while light snow will develop from the Great Lakes region into New England. Meanwhile, a storm system will begin to take shape across the West, resulting in generally light snow from the Sierra Nevada to the central Rockies.
During the last 2 days of February, significant snow will spread across the nation’s northern tier from the Dakotas into the Northeast. Meanwhile, mid-week rainfall could reach 1 to 3 inches from the central Gulf Coast region into the Mid-Atlantic States.
Farther west, additional storminess will overspread the Pacific Northwest during the mid- to late-week period.
Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures nationwide, except for cooler-than-normal weather in coastal California and the Northwest. Meanwhile, above-normal precipitation in the Northwest and much of the eastern one-third of the U.S. will contrast with drier-than-normal conditions in southern Florida and from California to the Plains.
