Across the Corn Belt, cool, drier air is arriving across the upper Midwest, following weekend thunderstorms. Unsettled, showery weather prevails, however, in the Ohio Valley and the lower Great Lakes region, bringing renewed disruptions to corn and soybean planting operations.
On the Plains, cooler, drier weather is overspreading northern areas, including the Dakotas. Meanwhile, warm weather accompanies scattered thunderstorms across the southern half of the region, except for persistent dryness on the drought-ravaged southern High Plains.
In the South, showers and locally severe thunderstorms continue across the Mid-South and the interior Southeast. Recovery efforts are underway in southwestern Missouri and neighboring areas, following Sunday’s devastating tornado in Joplin. Meanwhile across the Deep South, warm, dry weather favors fieldwork and crop development.
In the West, crop development remains sluggish due to persistently cool weather. In addition, a few showers linger across the Intermountain West.
A return to the hyperactive weather pattern that occurred in mid- to late April will continue for much of the week.
A pair of vigorous storms will result in 5-day rainfall totals of at least 1 to 3 inches across the central Plains, Mid-South, Ohio Valley, and lower Great Lakes region. Strong to locally severe thunderstorms will accompany the rainfall.
In contrast, dry weather will prevail in the lower Southeast and from southern California into western and southern Texas.
Warmth will linger for much of the week across the South and East, while cool weather will expand across the Plains and Midwest. Cool conditions will also persist in the West.
Looking ahead, the 6- to 10-day outlook calls for near- to above-normal normal temperatures nationwide, except for cooler-than-normal conditions in the Southeast and Northwest. Meanwhile, above-normal precipitation in the Atlantic Coast States, the northern Plains, and the Northwest will contrast with drier-than-normal conditions from the Southwest to the middle and lower Mississippi Valley.
