Seasonal heat, humidity to return to the Midwest...
Across the Corn Belt, cooler air is overspreading the Great Lakes region, while showers and thunderstorms are affecting the middle Mississippi and lower Missouri Valleys. Elsewhere, dry weather is promoting late-season planting efforts, especially in the eastern Corn Belt.
On the Plains, warm weather is promoting winter wheat maturation and summer crop emergence and growth, except across the northern tier of the region. Thursday’s high temperatures will approach 100° as far north as the central High Plains. Overnight showers soaked parts of eastern Kansas but provided local drought relief on the southern High Plains.
In the South, hot, dry weather continues to favor fieldwork and crop development. However, drought and hot conditions are taking an increasing toll on pastures and rain-fed summer crops across the Deep South.
In the West, cool weather continues to slow crop development and delay the peak snow-melt season, especially in California, the Great Basin, and the Northwest.
During the next five days, widely scattered showers and thunderstorms will affect mainly northern portions of the U.S. Rainfall totals could reach 1 to 2 inches in the upper Midwest and from northern California to the northern High Plains. Meanwhile, mostly dry weather will prevail in a broad area stretching from the Southwest to the lower Mississippi Valley. Cool weather will linger into next week across California, but most of the remainder of the U.S. will experience several days of near- to above-normal temperatures.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures across the central and southern Plains, Midwest, and Southeast, while cooler-than-normal weather will prevail across the northern High Plains and much of the West. Meanwhile, below-normal rainfall from the southern Rockies into the middle and southern Atlantic Coast States will contrast with wetter-than-normal conditions from the northern Rockies into the Great Lakes region.
