In the West, cold, stormy weather is engulfing the Pacific Northwest and the northern Rockies. Warmth prevails however, in the Four Corners States, where Arizona’s cotton harvest has passed the halfway mark.
On the Plains, bitterly cold air is moving into Montana, where only a portion of the winter wheat crop has a protective snow cover. A return to mild weather on the southern Plains is promoting cotton, peanut, and sorghum harvesting activities.
In the Corn Belt, temperatures are rebounding, following the recent cool spell. However, wet fields continue to hamper late-season fieldwork, including corn and soybean harvesting, in parts of the eastern Corn Belt.
In the South, cool, dry weather favors winter wheat planting and cotton, peanut, and soybean harvesting.
Outlook: A large, complex storm system will produce a swath of snow across the northern Rockies, Dakotas, and upper Midwest. However, a trailing cold front will produce little if any precipitation before stalling over the southcentral U.S. early next week, when an influx of Gulf moisture will lead to locally heavy rain from the southeastern Plains and northern Delta into the Ohio River Valley. Meanwhile, the coldest air of the season will briefly settle into northern portions of the Rockies and Plains, with daytime highs averaging up to 30°F below normal on Saturday. The air mass will modify as it moves east, resulting in marginally cooler conditions in the northern Great Lakes over the weekend. South of the front, daytime highs will average more than 12°F above normal across the southern Plains and Southeast. The NWS 6- to 10-day outlook for November 23-27 calls for near- to above-normal temperatures over much of the nation, with cooler-than-normal weather confined to the southern Pacific Coast. Wetter-than-normal conditions are expected west of the Rockies and from the northern Delta into Mid-Atlantic and Northeast. In contrast, below-normal precipitation will prevail over the Great Plains, upper Midwest, and southern Florida.
