USDA's Joint Ag Weather Facility says in the Corn Belt, locally severe thunderstorms are rolling across the Great Lakes region, largely north of the primary corn and soybean production areas. "Unfavorably hot, dry weather covers the remainder of the Midwest," USDA adds. 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%), according to USDA.
In the West, USDA says cool weather in the Pacific Coast states contrasts with lingering warmth farther inland. In the Four Corners states, USDA reports 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," USDA adds.
On the Plains, USDA says hot, mostly dry weather prevails. "Heat is maintaining stress on both rain-fed and irrigated summer crops, especially on the central Plains," USDA explains. Meanwhile, the winter wheat harvest is nearing completion on the central Plains and advancing onto the northern Plains, USDA reports.
In the South, USDA notes 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," USDA explains. However, stress is apparent on some reproductive summer crops, including corn and soybeans, according to USDA. "On July 1, nearly half of Kentucky's corn and soybeans (48% and 40%, respectively) were rated very poor to poor," USDA says.
In its outlook, USDA says 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," USDA reports. 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, according to USDA.
