An active Winter-like pattern over parts of the Nation...

On the Plains, a strong cold front separates warm weather across southern areas from bitterly cold, snowy, windy conditions in northern areas. Wednesday morning’s low temperatures generally ranged from 0 to -20 degrees in Montana but remained above 70 degrees in southern and eastern Texas. A variety of winter weather warnings and advisories are in effect on the northern Plains, where the newly dormant winter wheat crop remains protected under a substantial snow cover.

Across the Corn Belt, a chilly rain is quickly spreading across the middle Mississippi and lower Ohio Valleys, while some snow is beginning to develop in the upper Midwest. Midwestern harvest activities are virtually complete.

In the South, warm, mostly dry weather favors cotton harvesting and other late-season fieldwork.

In the West, unusually cold weather prevails. Wednesday morning’s temperatures fell below 0 degrees across much of the interior Northwest, although fresh snow is helping to insulate winter grains. Meanwhile, frost and freeze advisories were in effect in parts of California, including the Sacramento and San Joaquin Valleys.

For the remainder of Wednesday, rain will spread from the middle Mississippi Valley into the central and eastern Corn Belt, while snow will blanket the northern Plains and the upper Midwest. Blizzard conditions will engulf the central Rockies. Very cold conditions across the northern Plains and much of the West will contrast with unusual warmth from the southern Plains into the Southeast.

For Thanksgiving Day, snow and blowing snow will persist in the north-central U.S., while rain will fall from the Mid-South into the northern Mid-Atlantic States. Cold air will sweep across the southern Plains and the Midwest.

During the weekend, cold conditions will temporarily ease in the central U.S., while cold, wet weather will return across much of the West.

Looking ahead, the 6- to 10-day outlook for calls for near- to below-normal temperatures nationwide, except for warmer-than-normal weather in the Mid-Atlantic and Northeastern States. Meanwhile, near- to above-normal precipitation across the majority of the U.S. will contrast with drier-than-normal conditions across California, the Desert Southwest, the central and southern Plains, and Florida’s peninsula.
