In the West, cool weather continues to limit crop emergence and development. In addition, Northwestern showers are slowing fieldwork, including late-season spring wheat planting.

On the Plains, scattered showers and thunderstorms from Nebraska southward into Texas are slowing fieldwork but maintaining abundant moisture reserves for winter wheat and emerging summer crops. Cooler air is overspreading the northern High Plains, accompanied by scattered showers.

In the Corn Belt, the latest round of rain is overspreading the region from the southwest. The leading edge of rain stretches from eastern Nebraska to southern Illinois. Elsewhere in the Midwest, temporarily warm, dry weather favors a limited amount of fieldwork between storms.

In the South, warm, dry weather across the majority of the region favors crop growth and fieldwork, including cotton, peanut, and soybean planting. However, heavy showers and locally severe thunderstorms are spreading across the Mid-South, including Arkansas and western Tennessee.

Outlook: A major weather pattern change will take place during the next few days. The last in a series of storms will drift from the southern Plains into the Great Lakes region before weakening by Saturday. Meanwhile, an area of showers over the western Atlantic Ocean will drift westward and begin to affect the southern Atlantic States during the weekend and early next week. Farther west, a sustained period of cool, stormy weather will persist over the Northwest and by early next week will spread as far east as the northern Plains and the upper Midwest. Very cool air will also engulf the remainder of the West. The NWS 6- to 10-day outlook for May 25-29 calls for below-normal temperatures west of the Rockies, while warmer-than-normal weather will prevail across the Plains, Midwest, Mid-South, and Northeast. Meanwhile, above-normal precipitation from the Pacific Northwest into the upper Midwest will contrast with drier-than-normal conditions on the southern Plains and from the lower Great Lakes region into the Northeast.
