In the West, isolated showers are confined to the southern Rockies and the Northwest. For the most part, however, a warm, dry weather pattern continues to promote fieldwork and summer crop maturation.

On the Plains, showers continue across southeastern portions of the region, but dry weather elsewhere favors fieldwork and summer crop maturation. On the northern Plains, unusually warm weather is especially beneficial for late-developing crops.

In the Corn Belt, cool air is settling across the Great Lakes region, where frost was noted this morning in parts of northern Lower Michigan. Elsewhere, mild, dry weather is helping late-developing corn and soybeans advance toward maturity.

In the South, widespread showers and thunderstorms are slowing harvest activities and other fieldwork, but aiding pastures and boosting moisture reserves for fall-sown crops.

Outlook: A pesky, slow-moving storm system will continue to produce locally heavy showers from the southeastern Plains into the Southeast. During the next 5 days, as much as 2 to 5 inches of additional rain may fall from the Mid-South into the Southeast. During the weekend, rain will spread as far north as the Corn Belt, but most of the remainder of the nation will remain dry. Exceptions include the southern Rockies and the Pacific Northwest, where generally light showers can be expected. During the next several days, late-season warmth will be especially prominent in the West and across the nation’s northern tier as far east as the upper Midwest. The NWS 6- to 10-day outlook for September 22-26 calls for below-normal temperatures across the Plains, Midwest, and Southeast, while warmer- than-normal weather will be confined to New England and the Far West. Meanwhile, above-normal rainfall across the eastern half of the U.S. will contrast with drier-than normal conditions in the West.
