In the West, snow showers are ending across the southern Rockies. Mostly dry weather and below-normal temperatures cover the remainder of the region. The National Weather Service has issued frost advisories, effective early today, for some inland valleys in southern sections of California and Arizona.

On the Plains, locally heavy snow is blanketing western Oklahoma, northeastern New Mexico, and Texas’ northern panhandle. Farther east, rain showers are affecting other parts of Oklahoma and Texas. Meanwhile, mild, dry weather prevails across the northern Plains, initiating some melting of snow that has recently fallen.

In the Corn Belt, mostly dry weather accompanies near- to above-normal temperatures. However, some snow showers linger downwind of the Great Lakes. Snow cover exists across roughly the northern half of the region, from the Dakotas to Michigan.

In the South, a broken band of rain showers stretches across the region, excluding Florida’s peninsula. Topsoil moisture in Florida was rated 59% very short to short on February 10, only a slight improvement from 62% the previous week. In contrast, some lowland flooding persists in the central Gulf Coast region.

Outlook: An active weather pattern will prevail in many parts of the country through week’s end. A developing storm currently over the south-central U.S. will drift eastward, resulting in mid-week rain in the Southeast and some wet snow from the central Appalachians into southern New England. A late-week surge of cold air will trail the storm into the Plains and Midwest. During the weekend, there is the potential for a snow storm in the Mid-Atlantic and Northeastern States. Regardless of the weekend storm’s outcome, cold air will settle across the East by Sunday. Farther west, weekend temperatures will rebound to above-normal levels across the nation’s mid-section. Elsewhere, occasional rain and snow showers in the Northwest will contrast with generally dry weather from California into the Southwest. The NWS 6- to 10-day outlook for February 17-21 calls for near- to below-normal temperatures nationwide. The northern Plains will experience the greatest likelihood of colder-than-normal conditions. Meanwhile, below-normal precipitation in the West will contrast with wetter-than-normal weather in the upper Midwest and from the Mississippi River to the East Coast—excluding Florida’s peninsula.
