A quiet pattern across much of the Nation
Across the Corn Belt, scattered, mostly light showers linger in Iowa and Missouri. Recent rain has mostly bypassed Illinois, where short-term dryness is a concern for reproductive corn. Sunny skies are benefiting corn and soybeans development in the Ohio Valley.
On the Plains, excessive heat is rapidly building over drought-afflicted southern growing areas, where Wednesday’s highs will approach or exceed 100°F. Drier, warmer weather on the northern Plains is allowing spring wheat harvesting to resume.
In the South, varying degrees of drought persist from Texas into the Southeast, where increasingly hot conditions are rapidly offsetting the benefits of recent rain. However, some showers are falling in the northern Delta, while afternoon downpours in peninsular Florida are providing drought relief.
In the West, mostly dry weather continues to promote crop development and fieldwork, although monsoon showers linger in the Southwest.
A pair of cold fronts will produce widespread showers from the Corn Belt to the Atlantic Coast States into the weekend. Showers will be somewhat lighter in the Southeast, although locally heavy downpours are expected in peninsular Florida and the Northeast.
A brief spell of warm, sunny conditions on the northern Plains will gave way to notably cooler weather by week’s end.
Meanwhile, monsoon moisture will take a circuitous route out of the Southwest, resulting in showers and thunderstorms from the Four Corners into the central Plains, then southeastward into the Delta. Rain will bypass most of the southern Plains, where a compact ridge of high pressure will maintain sunny, excessively hot weather.
Seasonably dry weather is expected from the central and northern Rockies to the Pacific Coast.
Looking ahead, the 6- to 10-day outlook calls for drier- and warmer-than-normal weather from the Great Plains to the Pacific Coast. In contrast, cooler- and wetter-than-normal conditions are expected across much of the East.
