During the next few days, a sharp frontal boundary will develop from the southern Plains to the southern Appalachians. North of the boundary, cool, dry weather will cover the Great Lakes region.
Farther south, 5-day rainfall totals could reach 2 to 4 inches or more from central and eastern sections of Kansas and Oklahoma into the middle Atlantic States. Across the Deep South, humid weather will accompany scattered showers.
Meanwhile, little or no rain will fall west of the Rockies, where temperatures will rise to significantly above-normal levels.
