In the West, rain and high-elevation snow showers dot the central Rockies and the Intermountain region. Cool weather prevails, except for mild, dry weather in the Pacific Northwest.

On the Plains, rain is falling across central portions of the region. Some of the heaviest rain is falling in Nebraska and eastern Kansas. Dry weather is promoting some fieldwork on the northern Plains, but causing further drought intensification on the southern High Plains.

In the Corn Belt, cool, cloudy weather and scattered showers linger across eastern areas. Meanwhile, showers and thunderstorms are overspreading the southwestern Corn Belt, from Nebraska into Missouri. Elsewhere, dry weather continues to promote fieldwork in the upper Mississippi Valley.

In the South, mild, dry weather favors fieldwork and crop development, although drought persists in the western Gulf Coast region and portions of the southern Atlantic States. Early today, the Mississippi River crest (more than 14 feet above flood stage) is near Vicksburg, Mississippi.

Outlook: A slow-moving storm in the East will continue to weaken and drift northeastward, while a major storm system will take shape over the nation’s mid-section. Showers will linger into Friday in the Northeast, with an additional inch of rain possible in some areas. By early next week,  storm-total rainfall could reach 2 to 4 inches across the Plains (excluding the southern High Plains) and Mid-South. During the weekend and early next week, much of the Midwest could experience 1- to 2-inch totals. Farther west, some late-season snow will fall from the Cascades and the Sierra Nevada eastward into the northern and central Rockies. During the next several days, cool weather will prevail in the West, while warmth will expand across the South, East, and lower Midwest. The NWS 6- to 10-day outlook for May 24-28 calls for above-normal temperatures in the Gulf and Atlantic Coast States, while cooler-than-normal weather will prevail across the northern and central Plains and the upper Midwest. Meanwhile, near- to above-normal across the majority of the U.S. will contrast with drier-than-normal conditions across the nation’s southern tier.
