During the next couple of days, Southwestern moisture will spill across the southern Plains and interact with a cold front. As a result, storm-total rainfall could reach 2 to 5 inches from the southern Plains into the lower Mississippi Valley. Later, heavy showers will spread across the remainder of the Southeast. Farther east, locally heavy showers and thunderstorms will end by mid-week along the Atlantic Seaboard, where additional rainfall could total 1 to 3 inches. Elsewhere, hot, dry weather will persist in the Northwest, while cool, mostly dry weather will cover the Midwest.
Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures nationwide, except for cooler-than-normal conditions across parts of the interior Southeast. Meanwhile, below-normal rainfall in most areas from the Pacific Coast to the Plains will contrast with generally wetter-than-normal along and east of the Mississippi River.
