An active pattern in the days, weeks to come
Across the Corn Belt, wet snow is falling in parts of the Great Lakes region, especially in the vicinity of Lakes Michigan and Huron. Snow has ended across the western Corn Belt, while windy conditions and scattered rain showers are affecting Ohio Valley. Friday morning’s snow depths include 4 inches in Des Moines, Iowa, and Lansing, Michigan, and 5 inches in Sioux Falls, South Dakota, and Milwaukee, Wisconsin.
On the Plains, cool, dry weather prevails, except for lingering snow showers across northern areas. Winds have diminished on the southern High Plains, following Thursday’s dust storm.
In the South, cool, breezy weather prevails from the western Gulf Coast region into the lower Mississippi Valley. Meanwhile, showers and locally severe thunderstorms are sweeping across the Southeast, although Florida’s peninsula remains unfavorably warm and dry.
In the West, unfavorably dry conditions persist. The water equivalent of the high-elevation Sierra Nevada snow pack currently averages 7 inches, just 30 percent of normal for late February. Elsewhere, warm weather is returning to the Pacific Coast States, while cool conditions linger across the remainder of the region.
Precipitation will end later Friday or early Saturday across the East, except for lingering showers across the Deep South. During the weekend, snow will spread eastward across the nation’s northern tier.
Early next week, a late-winter storm will produce snow from the central Rockies into the upper Midwest, and showers and thunderstorms farther south and east. In the storm’s wake, colder air will return to the northern Plains and much of the West during the first half of next week. Meanwhile, temperatures will rebound to above-normal levels from the central and southern Plains into the East.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures across the eastern one-third of the U.S., while colder-than-normal weather will prevail in the West. Meanwhile, near- to above-normal precipitation across the majority of the U.S. will contrast with drier-than-normal conditions in the southern Atlantic region and from southern California to the southern High Plains.
