Across the Corn Belt, showers and thunderstorms are returning to areas from the Mississippi River westward, ending a window of opportunity for fieldwork. Some of the heaviest rain is falling in the upper Mississippi Valley. Meanwhile in the eastern Corn Belt, dry weather and gradually warmer conditions favor limited fieldwork, following extensive delays related to rainfall and flooding.
On the Plains, a chilly rain is curtailing spring wheat planting and other fieldwork in Montana and North Dakota. Across the remainder of the region, very warm, dry weather favors fieldwork and crop development. However, drought continues to severely stress pastures and winter wheat on the southern Plains, where Monday’s high temperatures will once again approach, reach, or exceed 100°. Wildfires remain a significant threat in drought-affected areas as far north as the central High Plains.
In the South, warm, mostly dry weather is promoting fieldwork and crop development. However, rain is needed in the western Gulf Coast region and portions of the southern Atlantic States.
In the West, unusually cool weather prevails. Mostly dry weather covers the Pacific Coast States, but widespread rain and snow showers dot the northern Rockies and Intermountain West.
During the next few days, a slow-moving storm system over the north-central U.S. will produce heavy rain (locally 1 to 3 inches) across parts of the northern Plains and upper Midwest. Snow will be mostly confined to the northern and central Rockies.
Farther east, several days of warm, dry weather will prevail across the heart of the Midwest during the storm’s approach. By week’s end, however, cool, showery weather will overspread the Midwestern and Mid-Atlantic States.
Looking ahead, the 6- to 10-day outlook calls for near- to below-normal temperatures nationwide, except for warmer-than-normal weather across the nation’s northern tier. Meanwhile, below-normal precipitation in New England, the Southwest, and the nation’s midsection will contrast with wetter-than-normal conditions in northern California, the Pacific Northwest, and the middle and southern Atlantic States.
