In the West, a slow-moving cold front is producing torrential precipitation in parts of the Northwest. Flooding is a threat in portions of Washington, Oregon, and northern Idaho, while a blizzard warning is in effect in western Montana along the Front Range of the northern Rockies. In stark contrast, mild, dry weather prevails from central and southern California to the central and southern Rockies.
On the Plains, dry, unusually warm weather is maintaining stress on hard red winter wheat. Today’s high temperatures will approach 70°F as far north as western Nebraska.
In the Corn Belt, light rain showers are crossing the Mississippi and lower Missouri Valleys. Meanwhile, mild, dry weather in the eastern Corn Belt is promoting late-season harvest efforts.
In the South, a low-pressure system lurking east of Georgia is producing some rain across North Carolina’s Outer Banks. Cool conditions linger in the southern Atlantic States, but mild, dry weather across the remainder of the region favors winter wheat planting, cotton and soybean harvesting, and other autumn fieldwork.
Outlook: For the remainder of the week, significant precipitation will be confined to the Northwest. Five-day totals could reach 2 to 4 inches in the northern Rockies and 4 to 10 inches in the Pacific Northwest. Elsewhere, little or no precipitation can be expected through mid-week. By Thanksgiving Day, November 22, a low-pressure system crossing south-central Canada will produce some snow across the northern Plains and light rain showers from Texas to the Great Lakes region. Toward week’s end rain showers will change to snow showers in the Great Lakes States. A warm weather pattern across most of the U.S. will be replaced by somewhat cooler conditions late in the week across the eastern half of the U.S. The NWS 6- to 10-day outlook for November 24-28 calls for near- to above-normal temperatures nationwide, except for cooler-than-normal conditions in all of the Atlantic Coast States but Maine. Meanwhile, below-normal precipitation across roughly the southern two-thirds of the U.S. will contrast with wetter-than-normal weather across the nation’s northern tier from the Pacific Northwest to the Great Lakes region.
