In the West, very warm, dry weather continues to promote a rapid pace of fieldwork and crop growth. Warmth is accelerating the snow-melt rate across the Cascades and the northern Rockies.
On the Plains, dry weather favors fieldwork. Record-setting warmth continues to expand across the northern and central High Plains, where today’s high temperatures will approach 90°F.
In the Corn Belt, cool air covers the Great Lakes region, although this morning’s scattered frost was confined to northern sections of Minnesota, Wisconsin, and Michigan—well outside the primary agricultural region.
In the South, unsettled weather continues to provide drought relief in the southern Atlantic States. Currently, some of the heaviest rain is overspreading Florida. In contrast, drought continues to develop and expand across the Mid-South, including the northern Mississippi Delta.
Outlook: During the next several days, much of the nation will experience warmer-than-normal weather. Exceptions will include a brief surge of cool air across the Great Lakes and Northeastern States, and a shortlived, late-week cool spell across the West. Meanwhile, showers will linger for several days across the lower Southeast, providing additional drought relief. Elsewhere, significant late-week precipitation will be confined to the northern Rockies, northern and central Plains, and the upper Midwest. The NWS 6- to 10-day outlook for May 21-25 calls for near- to above-normal temperatures nationwide, except for cooler-than-normal conditions across the lower Southeast. Meanwhile, below-normal rainfall from southern California to the central and southern High Plains will contrast with wetter-than-normal weather in the Pacific Northwest, the southern Atlantic region, and areas from the southeastern Plains into the eastern Corn Belt.
