In the West, 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.
On the Plains, 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. The core of extreme heat is centered over the central High Plains, where highs above 105°F can be expected today.
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. Today’s maximum temperatures will again approach, reach, or exceed 100°F in the southwestern Corn Belt.
In the South, a weak tropical disturbance continues to spark scattered showers across Florida’s peninsula. A few showers are also affecting the western Gulf Coast region. Elsewhere, hot, dry weather favors rapid crop development, but is stressing pastures and summer crops in areas with inadequate soil moisture.
Outlook: 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. Prospects for Midwestern drought relief will improve this week, especially in the northern and eastern Corn Belt. Five-day rainfall totals could reach 1 to 3 inches, with locally higher amounts, from the Dakotas to Michigan and Ohio. However, 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. Elsewhere, occasional showers could result in 1- to 2-inch rainfall totals in the Four Corners States and the lower Southeast. The NWS 6- to 10-day outlook for July 28 – August 1 calls for hotter-than-normal weather nationwide, except for near- to belownormal temperatures west of the Rockies and from the lower Great Lakes region into New England. Meanwhile, drier-than-normal weather from the central and southern Plains into the lower Southeast will contrast with abovenormal rainfall from the northern Plains to the Mid-Atlantic region, including portions of the Midwest.
