USDA's Joint Ag Weather Facility says in the Corn Belt, a band of widely scattered but highly beneficial showers stretches from South Dakota into northern Ohio. "However, unfavorably hot conditions persist in much of the Midwest," USDA adds. Today's maximum temperatures will again approach, reach, or exceed 100°F in the southwestern Corn Belt, USDA explains.
In the West, USDA reports monsoon showers are affecting the Great Basin and the Intermountain region. "Elsewhere, seasonably warm weather in California's Central Valley contrasts with cool conditions in the Northwest," USDA reports.
On the Plains, USDA says favorably cooler weather prevails in the Dakotas. "Farther south, however, heat and drought are maintaining severe stress on pastures and summer crops on the central and southern Plains," USDA explains. The core of extreme heat is centered over the central High Plains, where highs above 105°F can be expected today, according to USDA.
In the South, USDA reports a weak tropical disturbance continues to spark scattered showers across Florida's peninsula. "A few showers are also affecting the western Gulf Coast region," USDA adds. Elsewhere, hot, dry weather favors rapid crop development, but is stressing pastures and summer crops in areas with inadequate soil moisture, USDA explains.
In its outlook, USDA says unfavorably hot weather will persist early in the week across the Plains and Midwest. "During the second half of the week, however, markedly cooler air will overspread the northern and central Plains and the Midwest," USDA says. Prospects for Midwestern drought relief will improve this week, especially in the northern and eastern Corn Belt, USDA reports. "Five-day rainfall totals could reach 1 to 3 inches, with locally higher amounts, from the Dakotas to Michigan and Ohio," USDA explains. However, USDA says only light showers can be expected across the southwestern Corn Belt, from Nebraska to southern Illinois. "Unfavorably dry conditions will also persist on the central and southern Plains," USDA adds. Elsewhere, occasional showers could result in 1- to 2-inch rainfall totals in the Four Corners States and the lower Southeast, according to USDA.
