In the West, highly variable conditions exist. Snow is falling in parts of Wyoming, while warm, dry, breezy weather is increasing the threat of wildfires in western Oregon and parts of California. In California and the Desert Southwest, fieldwork is advancing with few delays.

On the Plains, a chilly rain is falling across northern and central portions of the region, excluding Montana. Cool, dry weather has returned to Montana. Meanwhile on the southern Plains, warm, mostly dry weather favors summer crop maturation and fieldwork, including winter wheat planting.

In the Corn Belt, warm weather continues to promote corn and soybean maturation. However, an area of favorably dry weather in the central Corn Belt contrasts with showery conditions in both eastern and western portions of the region.

In the South, local flooding and heavy showers persist in the southern Appalachians and neighboring areas, where many locations have received at least 5 inches of rain in the last week. Meanwhile, drier air is spreading into the Mid-South, although wet soils continue to delay harvest activities and other fieldwork.

Outlook: Early in the week, a slow-moving storm system centered over the nation’s mid-section will produce early-season snow in the central Rockies and widespread rain showers from the Plains to the Appalachians. By week’s end, additional rainfall may total as much as 1 to 3 inches from the eastern Plains into the Mississippi and Ohio Valleys. Cool weather will linger for several days in the vicinity of the storm system, but above-normal temperatures will prevail across the remainder of the U.S. Especially warm weather will prevail in the Far West and across the nation’s northern tier. The NWS 6- to 10-day outlook for September 26-30 calls for below-normal temperatures east of a line from Texas to Wisconsin, while warmer-than-normal weather will prevail in the West. Meanwhile, below-normal precipitation across the western half of the U.S. will contrast with wetter- than-normal conditions from the Mid-Atlantic coastal plain into New England.
