In the West, cool weather persists. A frost advisory is in effect this morning across parts of California’s San Joaquin Valley. Precipitation is confined to the Pacific Northwest and portions of the Desert Southwest.

On the Plains, dry weather prevails. A patchy, shallow snow covers exists across the northern half of the region, but much of the Plains’ winter wheat crop remains exposed to potential weather extremes.

In the Corn Belt, mild, unfavorably dry conditions continue across the upper Midwest. In contrast, the latest round of precipitation—light rain—is falling in the eastern Corn Belt.

In the South, dry weather has temporarily returned to the western Gulf Coast region, except for showers in Deep South Texas. Meanwhile, rain showers are providing drought relief in the southern Atlantic States, but largely bypassing Florida’s peninsula.

Outlook: For today, rain will affect much of the East. However, Florida’s peninsula will remain mostly dry, while some wet snow will blanket the interior Northeast. Meanwhile, a new storm will begin to take shape over the southcentral U.S. By early Saturday, a low-pressure system will develop along the western Gulf Coast and drift northeastward. The storm system will reach the southern Mid-Atlantic Coast on Sunday. Storm-total rainfall could reach 1 to 3 inches from the western Gulf Coast region into the Southeast—excluding southern Florida—while wet snow may blanket the central Appalachians and neighboring areas. Elsewhere, significant precipitation will be confined to the northern Rockies and Pacific Northwest, although light rain and snow showers will overspread the Intermountain West during the weekend. The NWS 6- to 10-day outlook for February 21-25 calls for near- to below-normal temperatures nationwide, except for warmer-than-normal weather in the Great Lakes and Atlantic Coast States. Meanwhile, near- to above-normal precipitation across the majority of the U.S. will contrast with drier-than-normal conditions from California to western Texas.
