USDA's Joint Ag Weather Facility says in the Corn Belt, growing conditions remain mostly favorable for reproductive to filling corn and soybeans, as near- to below-normal temperatures accompany widely scattered showers. Lingering pockets of dryness are most widespread in the lower Great Lakes region, mainly covering portions of Ohio and Michigan.
In the South, warm, humid weather prevails. Recent rainfall dented summer rainfall deficits in the Mississippi Delta and environs, helping to ease stress on pastures and immature summer crops. However, short-term drought persists in several areas, most extensively in a broad area centered on the southern Appalachians.
On the Plains, generally cool weather and scattered showers are helping to ease the stressful effects of last week’s heat on pastures, livestock and summer crops. However, hot weather lingers on the southern High Plains, where a four-week heat wave has adversely affected rain-fed summer crops, including cotton.
In the West, hot, dry weather prevails, except along the immediate Pacific Coast. More than two dozen wildfires are active across the West and lightning strikes could ignite new fires in the Sierra Nevada and the Great Basin.
In its outlook, USDA says during the next several days, loosely organized shower activity will continue across most of the central and eastern U.S., accompanied by mostly near- to below-normal temperatures. Exceptions will include the southern Atlantic States, where hot, humid weather will persist, and the High Plains, where heat will return during the weekend and early next week. Five-day rainfall totals could reach 1 to 3 inches across the mid-South and 2 to 4 inches from the Mid-Atlantic States into New England. Other parts of the central and eastern U.S. could receive as much as 1 to 2 inches. Elsewhere, ongoing heat in the West will be accompanied by scattered showers in the monsoon region—mainly the Four Corners States and neighboring areas.
