A wide-range of temperatures across the Heartland
Across the Corn Belt, scattered frost was noted this morning, although little or no corn had emerged in the freeze-affected areas. Monday morning’s preliminary low temperatures included 28° in Madison, Wisconsin; 31° in Sioux City, Iowa; and 32° in both South Bend, Indiana, and Moline, Illinois.
On the Plains, dry weather favors fieldwork, winter wheat development, and summer crop emergence and growth. Record-setting warmth prevails across the northern half of the High Plains, where Monday’s high temperatures will approach 90°.
In the South, cool, dry weather prevails, except for some lingering showers in the southern Mid-Atlantic region. In the previously parched Atlantic Coast States, pastures, winter grains, and emerging summer crops are benefiting from recent soil moisture improvements.
In the West, very warm, mostly dry weather is promoting a rapid pace of fieldwork and crop development. Washington’s spring wheat planting, which had been lagging the normal pace (30% planted on April 15, compared to the 5-year average of 49%) is accelerating.
Record-setting warmth across the northern High Plains and much of the West will gradually shift eastward during the early- to mid-week period. During the second half of the week, warmth will arrive across the South, while markedly cooler air will engulf the West. Cooler-than-normal conditions will persist for much of the week across the Midwest and Northeast.
Elsewhere, early-week storminess in the Northeast will include late-season snowfall from the central Appalachians into western New York. By mid-week, scattered showers will return to parts of the Midwestern and Mid-Atlantic States, while showery, cooler weather will overspread the West. Toward week’s end, showers and thunderstorms will erupt across the northern and central Plains.
Looking ahead, the 6- to 10-day outlook calls for warmer-than-normal weather nationwide, except for near- to below-normal temperatures in the Far West. Meanwhile, above-normal precipitation from the Pacific Northwest to the Plains and upper Midwest will contrast with drier-than-normal conditions in the East and Southwest.
