In the West, chilly weather lingers across the central and southern Rockies. Elsewhere, hot, dry conditions favor fieldwork, including Northwestern winter wheat planting, California’s rice harvest, and Arizona’s cotton harvest.

On the Plains, dry, unusually warm weather across northern areas is promoting spring wheat harvesting and winter wheat planting. In contrast, a chilly rain lingers on the central High Plains, while cool air has settled across the central and southern Plains.

In the Corn Belt, mild weather continues to push late-developing corn and soybeans toward maturation, although scattered showers dot eastern areas. A small amount of summer crop harvesting is underway; by September 20, for example, soybeans were 2% harvested in Iowa and 1% harvested in Nebraska.

In the South, river flooding continues in parts of the southern Appalachians and surrounding areas. Meanwhile, showery weather is providing additional drought relief in southern Texas, but perpetuating fieldwork delays and threatening the quality of unharvested crops in the lower Mississippi Valley.

Outlook: A slow-moving storm system over the central Plains will eventually drift northeastward. As a result, showers will diminish across the central Plains, although as much as 1 to 3 inches of additional rain may fall from the Mississippi River to the East Coast. In the storm’s wake, warm, dry weather will prevail into early next week from the West Coast to the Plains. Early next week, a surge of cool air will arrive across the Midwest and Northeast. The NWS 6- to 10-day outlook for September 28 – October 2 calls for cooler-than normal weather across the eastern half of the U.S., while near- to above-normal temperatures will prevail in the West. Meanwhile, below-normal precipitation across the northern Plains and the Midwest will contrast with wetter-than-normal conditions in New England, the Pacific Northwest, and from the central and southern Rockies to the Gulf Coast region.
