Rains on parts of the Plains shift into some of the Corn Belt
Across the Corn Belt, widespread showers are causing renewed fieldwork delays, after 50% of the intended U.S. corn acreage was planted during the 2-week period ending May 22. Ironically, the Red River Valley of the North—where planting delays have been particularly acute—remains dry on Wednesday, although high temperatures will stay below 70°F. Amid the latest rain event, Wednesday’s high temperatures in parts of the upper Mississippi Valley will barely top the 50-degree mark.
On the Plains, a low-pressure system moving across the Ozark Plateau is resulting in cool weather and lingering showers. Early Wednesday, rain is confined to the eastern Plains. Wednesday’s high temperatures will remain mostly below 60°F from central Oklahoma into eastern South Dakota. Meanwhile, dry weather has returned across the central and southern High Plains, following drought-easing rainfall that primarily benefited rangeland, pastures, and summer crops.
In the South, rain has largely ended across the Atlantic Coast States, but other areas continue to experience widespread showers and thunderstorms. The rain is limiting fieldwork but generally benefiting pastures and summer crops, except in areas where flash flooding is occurring.
In the West, hot weather has returned across California and portions of neighboring states. Wednesday’s high temperatures will reach 100°F or higher as far north as California’s Sacramento Valley. Any Western precipitation is limited to the northern tier of the region, from Washington to northwestern Montana. Elsewhere, poor air quality plagues portions of southern New Mexico due to smoky conditions related to the Black and Bear Trap Fires.
