Heat wave pattern continues throughout the Heartland

Heat wave pattern continues throughout the Heartland

Across the Corn Belt, unfavorably hot, dry weather covers the Midwest. By July 1, one-fifth to one-half of both corn and soybeans were rated very poor to poor in Indiana (50 and 43%, respectively, for corn and soybeans), Missouri (48 and 49%), Illinois (33 and 31%), Michigan (28 and 27%), Ohio (26 and 30%), and Wisconsin (24 and 25%).

On the Plains, hot, mostly dry weather prevails. Heat is maintaining stress on both rain-fed and irrigated summer crops, especially on the central Plains. Meanwhile, the winter wheat harvest is nearing completion on the central Plains and advancing onto the northern Plains.

In the South, temperatures have fallen slightly from recent record-high levels but remain above normal. Despite the ongoing heat wave, conditions remain mostly favorable for crops such as peanuts and rice. However, stress is apparent on some reproductive summer crops, including corn and soybeans. On July 1, nearly half of Kentucky’s corn and soybeans (48 and 40%, respectively) were rated very poor to poor.

In the West, cool weather in the Pacific Coast States contrasts with lingering warmth farther inland. In the Four-Corners States, an increase in the coverage and intensity of monsoon shower activity is aiding wildfire containment efforts. Showers are also affecting the northern Rockies and the Pacific Northwest.

Hot weather will continue during the next several days across much of the U.S., although favorably cooler air will arrive late in the week in the upper Midwest. Thunderstorms will accompany the surge of cooler weather across the northern Plains and upper Midwest. Meanwhile, dry weather will persist through week’s end across the central and southern Plains and the southern half of the Corn Belt, but showers will increase in the Southeast and Southwest.

Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures nationwide. The greatest likelihood of hot weather will occur across northern portions of the Rockies and Intermountain West. Meanwhile, above-normal rainfall in southern parts of the Rockies and High Plains and the middle and southern Atlantic coastal plain will contrast with drier-than-normal conditions in the Midwest and Pacific Northwest.
