In the West, cool weather prevails in the southern Rockies and along the immediate Pacific Coast. Elsewhere, dry weather and record-setting high temperatures are promoting a rapid pace of fieldwork and crop development. Today’s high temperatures will again exceed 90°F in parts of the interior Northwest.

On the Plains, showers linger across central and southern Texas, mainly south of the winter wheat belt. Across the northern and central High Plains, where today’s high temperatures will approach 90°F, both fall- and spring-sown small grains are developing at a faster-than-normal pace.

In the Corn Belt, a weak cold front is crossing the upper Midwest. Slightly cooler air trails the front, while warm, dry weather across the remainder of the Midwest is promoting fieldwork and crop growth.

In the South, rain showers are affecting central and southern Texas and portions of the Atlantic coastal plain. In both regions, rain continues to chip away at precipitation deficits. However, the southern Atlantic States and parts of Alabama are still in need of substantial rainfall to ease the effects of drought on crops and water supplies.

Outlook: Rain will largely end across the East by mid-week, although beneficial showers may linger across the southern Atlantic States. During the second half of the week, a warm, dry weather pattern will cover the majority of the nation. However, there will be a brief surge of cool air across the Great Lakes and Northeastern States. Toward week’s end, cooler air will arrive in the West. Briefly cooler weather will reach the Plains during the weekend. Scattered showers will precede and accompany the cooler conditions across the north-central U.S. The NWS 6- to 10-day outlook for May 20-24 calls for near- to above-normal temperatures nationwide, except for cooler-than-normal conditions along the Gulf Coast. Meanwhile, near- to below-normal rainfall across the majority of the U.S. will contrast with wetter-than-normal weather in the Pacific Northwest, the southern Atlantic region, and from the central and southern Plains into the western Corn Belt.
