An active pattern to continue into next week...
Across the Corn Belt, cold air is overspreading the upper Midwest. Meanwhile, snow is falling across much of the lower Great Lakes region, while rain showers linger in the Ohio Valley.
On the Plains, a surge of very cold air continues to push southward. Friday morning’s low temperatures fell below -30° in parts of northern Montana and dipped to 0° as far south as Nebraska. On the central and southern Plains, pastures and winter grains are benefiting from recent topsoil moisture improvements, although precipitation largely bypassed the High Plains region.
In the South, recovery efforts from severe thunderstorms are underway. Localized wind damage was reported Thursday and Thursday night from Arkansas and northern Louisiana eastward into the southern Appalachians. However, Southern showers are also providing some relief from ongoing drought.
In the West, rain and snow showers stretch from northern and central California into the Intermountain region. Meanwhile, very cold air continues to settle across the Northwest in the wake of recent snowfall.
A low-pressure system over the lower Great Lakes region will race northeastward, followed by a period of windy, colder weather across the Plains, Midwest, and Northeast. However, bitterly cold air will remain confined to the northern Plains and upper Midwest.
Very cold air will also overspread the West, preceded and accompanied by rain and snow showers. During the weekend, freezes may occur in some agricultural regions of California where crops, such as fruit trees, have begun to exhibit spring development.
Early next week, mild weather will return to the East in advance of a new storm system, while chilly conditions will linger in the West. The new storm could produce locally severe thunderstorms across the South and snow from the central Plains into the Great Lakes region.
Looking ahead, the 6- to 10-day outlook calls for generally colder- and wetter-than-normal weather across the northern tier of the U.S., while above-normal temperatures and below-normal precipitation will cover the southern one-third of the U.S.
