Across the Corn Belt, showers and thunderstorms across are providing beneficial moisture for immature summer crops across the far upper Midwest, including North Dakota and parts of Minnesota. Across much of the remainder of the Midwest, however, persistent dryness and increasingly hot conditions are maintaining significant stress on pastures and immature corn and soybeans.
On the Plains, precipitation is confined to the northern tier of the region, including parts of Montana and North Dakota. The northern Plains’ rain is slowing late-season spring wheat harvesting efforts. Meanwhile, hot, dry weather on the central and southern Plains favors fieldwork but is maintaining stress on rangeland, pastures, and immature summer crops in areas with inadequate soil moisture reserves.
In the South, warm, mostly dry weather continues to promote summer crop maturation and harvesting. Conditions have improved in the Southeast, following a wet summer, but drought is gradually expanding and intensifying from the western Gulf Coast region into the lower Mississippi Valley.
In the West, showery weather from Arizona to southeastern Wyoming contrasts with hot, dry weather in the Pacific Coast States and the northern Rockies.
A robust, late-season monsoon circulation will continue to funnel tropical moisture into the Southwest. As a result, 5-day rainfall totals of 2 to 4 inches in the Four Corners States could trigger flash flooding. Some of the Rain will spill across the central Rockies onto the central High Plains, where as much as 1 to 3 inches could occur. Most of the remainder of the U.S. will receive little or no rain, except for 1- to 3-inch totals in southern sections of Florida and Texas, as well as the nation’s northern tier from the upper Great Lakes region into New England. Meanwhile, late-season heat will continue to dominate much of the nation, except for rain-cooled conditions in the Southwest. Toward week’s end, however, markedly cooler air will arrive in the Great Lakes and Northeastern States.
The 6- to 10-day outlook calls for near- to above-normal temperatures nationwide and below-normal rainfall across the majority of the country. Wetter-than-normal weather will be limited to the Deep South and scattered areas from the Plains, westward.
