Across the Corn Belt, cool weather lingers from the Mississippi Valley eastward. Meanwhile, above-normal temperatures continue to expand across the upper Midwest. Dry weather throughout the Corn Belt is reducing topsoil moisture. On June 14, Nebraska led the Corn Belt with topsoil moisture rated 38% very short to short, followed by North Dakota (33%) and Indiana (29%).
On the Plains, widely scattered showers are limited to parts of Montana. Cooler air is also overspreading Montana, but much of the remainder of the region continues to experience hot, dry weather leading to “flash drought” conditions. During the week ending June 14, topsoil moisture rated very short to short increased at least 10 percentage points in each of the Plains States except Montana and South Dakota. On the 14th, Colorado led the region with topsoil moisture rated 75% very short to short, followed by Oklahoma (69%), Texas (64%), and Kansas (53%).
In the South, a low-pressure system centered east of the Georgia coast continues to produce locally heavy showers in Virginia and the Carolinas. Cool but mostly dry weather covers the remainder of the South, favoring winter wheat harvesting and other fieldwork. Nationally, 89% of the cotton and 95% of the peanuts had been planted by June 14.
In the West, widespread showers accompany unusually cool conditions from the Pacific Northwest to the northern Rockies. Meanwhile, warm, breezy, dry weather is maintaining an elevated wildfire threat in parts of the Great Basin and the Southwest. On June 14, one-third to one-half of the rangeland and pastures were rated in very poor to poor condition in California (50%), New Mexico (48%), Colorado (40%), and Oregon (35%).
Additional rainfall in Virginia and the Carolinas could total 1 to 4 inches or more, as a low-pressure system drifts northward and moves inland across the mid-Atlantic. Meanwhile, a slow-moving cold front will generate scattered showers and thunderstorms from the Pacific Northwest into the upper Midwest. Five-day rainfall totals should range from 1 to 2 inches across portions of the upper Midwest and northern sections of the Rockies and High Plains. Most of the remainder of the country, including New England and a broad area from California to the Mississippi Delta, will remain mostly dry through week’s end. Heat in the nation’s mid-section will shift eastward, later reaching the Great Lakes and Northeastern States. Elsewhere, cooler weather will arrive on the Plains, but heat will develop during the second half of the week in the Pacific Coast States.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of near- or above-normal temperatures and rainfall across most of the country. Cooler-than-normal conditions will be confined to parts of the Midwest, while drier-than-normal weather should be limited to the lower Southwest and from the Pacific Northwest into the far upper Midwest.
