In the West, winter storm warnings are in effect across portions of the northern Rockies due to heavy, wet snow. Lower elevations of the interior Northwest are receiving a chilly rain, which is halting fieldwork but boosting topsoil moisture for winter wheat establishment. Unusually cool weather prevails throughout the region, except for lingering warmth in the southern Rockies.

On the Plains, warm, dry weather across the majority of the region favors summer crop maturation and fieldwork, including harvest activities and winter wheat planting. However, sharply colder air is overspreading the northern High Plains, accompanied by a few rain showers.

In the Corn Belt
, warm, dry weather is ideal for corn and soybean maturation, as well as initial winter wheat planting efforts. However, soil moisture shortages remain a concern in many areas, with the latest U.S. Drought Monitor indicating that 79% of Iowa, 53% of Minnesota, and 41% of Illinois are in drought.

In the South, showers are confined to areas along the southern Atlantic Coast. Elsewhere, warm, dry weather is promoting summer crop maturation and harvesting.

Outlook: Snow will subside later today or on Friday across the northern Rockies, while a few showers will linger along the southern Atlantic Coast. On Friday, widespread showers will erupt across the nation’s mid-section, primarily from western Texas to the eastern Dakotas and northwestern Minnesota. During the weekend, showers will shift eastward and gradually become less numerous. Five-day precipitation totals could reach 1 to 3 inches in the south-central U.S., including much of Texas, and in parts of the upper Midwest. Mostly dry weather will prevail in the East, except along the southern Atlantic Coast, and in the Southwest. However, heavy precipitation will begin to overspread the Pacific Northwest on Friday, with 5-day totals reaching 4 to 8 inches or more. The NWS 6- to 10-day outlook for October 1-5 calls for near- to above-normal temperatures nationwide, except for cooler-thannormal conditions in a small area centered on the Four Corners region. Meanwhile, near- to below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal weather in the Pacific Northwest and a broad area stretching from the Gulf Coast into the lower Great Lakes region.
