In the West, cool weather lingers across the southern Rockies. Elsewhere, very warm, dry weather is promoting a rapid pace of fieldwork and crop development. Today’s high temperatures will reach 90°F across portions of the interior Northwest.

On the Plains, warm, dry weather across the northern half of the region favors rapid development of winter and spring wheat. In contrast, cool, showery weather on the southern High Plains is providing some relief from long-term drought.

In the Corn Belt, dry, warmer conditions favor soybean and late-season corn planting. Emerged summer crops continue to benefit from soil moisture improvements associated with early-May rainfall.

In the South, rain showers are affecting areas from the Appalachians eastward. Some of the heaviest rain, in the southern Mid-Atlantic States, is helping to reduce year-to-date precipitation deficits.

Outlook: Aside from cool conditions early in the week across the south-central U.S. and parts of the East, much of the country will experience near- to above-normal temperatures during the next several days. Toward week’s end, however, cooler air will overspread the West. Rain will largely end by mid-week in the Rio Grande Valley and the eastern U.S., although 1- to 2-inch totals may occur in both regions before precipitation ends. Mostly dry weather will prevail across the remainder of the U.S., except for late-week showers from the northern Rockies to the Great Lakes region. The NWS 6- to 10-day outlook for May 19-23 calls for warmerthan- normal weather nationwide, except for near- to below temperatures in parts of Texas and the southern Atlantic region. Meanwhile, near- to below-normal rainfall across the majority of the country will contrast with wetter-than-normal conditions in the north-central U.S. and from eastern Texas to the southern Atlantic States.
