Substantially cooler air will overspread the Plains and the Midwest during the weekend.
By early next week, near- to below-normal temperatures will cover all areas east of the Rockies, except for a return to hot weather on the northern High Plains. Meanwhile, heat will quickly build west of the Rockies, with record-high temperatures possible in parts of the Northwest.
During the next 5 days, rainfall will be focused in two primary areas: the Southeast (as much as 2 to 4 inches) and the central and southern Rockies (locally 1 to 4 inches). Early in the period, rain (locally 1 to 2 inches) will also affect parts of the upper Midwest, but only light showers can be expected across the remainder of the parched Corn Belt.
