Across the Corn Belt, a few showers and thunderstorms are confined to areas west of the Mississippi River. Across the eastern Corn Belt, dry weather and near- to slightly below-normal temperatures favor summer crop development. However, dryness remains a concern in some areas, including a strip from southeastern Iowa into central Indiana.
On the Plains, hot weather accompanies diminishing areas of shower activity. Across the northern Plains, late-summer heat favors winter and spring wheat harvesting. Meanwhile, drought continues across the south-central U.S., despite sporadic August rainfall.
In the South, showers are ending along the southern Atlantic Coast, except across Florida’s peninsula. Very warm weather continues to stress some Southern pastures and immature summer crops.
In the West, isolated showers are confined to the Four Corners States, while cool conditions are limited to the immediate Pacific Coast. Elsewhere, warm, dry weather favors fieldwork and crop development.
Much of the U.S. will experience above-normal temperatures for the remainder of the week. Exceptions will include the Northeast (cool early in the week) and the immediate Pacific Coast.
During the next few days, significant rainfall will be mostly confined to northern portions of the Midwest and scattered locations in Florida and the Southwest. Late in the week, however, Hurricane Irene will threaten the southern Atlantic Coast. Landfall could occur as early as Thursday night along Florida’s east coast, but will occur later and farther north if Irene veers northward before reaching Florida. Hurricane Irene was centered about 90 miles west-northwest of San Juan, Puerto Rico, moving toward the west-northwest at 14 mph.
Looking ahead, the 6- to 10-day outlook calls for below-normal temperatures across the eastern two-thirds of the U.S., while warmer-than-normal weather will prevail in much of the West. Meanwhile, below-normal rainfall in southern Texas and the Far West will contrast with wetter-than-normal conditions in the East.
