In the West, a developing storm centered over Nevada is producing widespread rain and snow showers, as well as breezy conditions, from the Sierra Nevada to the northern Rockies. Blustery conditions are also affecting the Southwest, enhancing the risk of wildfires in some areas.

On the Plains, a winter storm warning is in effect for much of central and western Montana, where snow is already falling. This morning’s low temperatures in Montana generally ranged from 20 to 30°F, with some lower readings near the Canadian border. Elsewhere, dry weather favors fieldwork, although lingering warmth across the southeastern half of the Plains contrasts with chilly conditions farther north and west.

In the Corn Belt, mild weather across the southern tier of the Midwest favors harvest activities and winter wheat emergence. Meanwhile, cold weather prevails from Nebraska and the Dakotas eastward to Michigan.

In the South, scattered showers are causing minor fieldwork delays. During the weekend, however, dry weather in the Southeast favored winter wheat planting and harvest activities for a variety of summer crops.

Outlook: A developing storm over the Intermountain West will drift eastward, reaching the central Plains by midweek. By November 1, the low-pressure system will be crossing eastern Canada, with a trailing cold front along the Atlantic Seaboard. Five-day rainfall totals could reach 1 to 3 inches in many areas from the eastern Plains to the Appalachians, with 5-inch totals possible from northeastern Texas to northern Missouri. Meanwhile, the storm will also produce significant, late-October snowfall (6 to 18 inches) across portions of the northern Rockies, northern High Plains, and Intermountain West. The NWS 6- to 10-day outlook for November 2-6 calls for near- to below-normal temperatures nationwide, except for warmer-than-normal weather across the Deep South. Meanwhile, near- to below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal conditions in southern Florida, southeastern New Mexico and parts of Texas, and from Montana to Michigan.
