Across the Corn Belt, very warm weather is building into southern corn and soybean production areas, where Wednesday’s high temperatures will exceed 90°. Elsewhere, beneficial showers dot the eastern Corn Belt, while favorably warm weather is aiding late-developing summer crops in the upper Midwest.
On the Plains, hot, dry weather is increasing stress on immature summer crops as far north as southern Nebraska. Temperatures could reach 100° later Wednesday in western Kansas and environs. In contrast, scattered showers on the northern Plains are slowing fieldwork, including spring wheat harvesting.
In the South, isolated showers are causing only minor fieldwork delays. On August 17, Texas led the South with 32% of its corn harvested, followed by Georgia (31%), South Carolina (19%), and Louisiana (12%).
In the West, widely scattered, monsoon-related showers stretch primarily from Arizona to the northern Rockies. Mostly dry weather prevails in the Pacific Coast States, although cooler weather is aiding wildfire containment efforts.
