Across the Corn Belt, much cooler air is arriving. Wednesday morning’s temperatures fell to 40° or slightly below in parts of the far upper Midwest. Additional rain is still needed in portions of the central and eastern Corn Belt to prevent further declines in crop condition.
On the Plains, a Frost Advisory was in effect early Wednesday morning in parts of central and eastern North Dakota, where minimum temperatures fell to near the freezing mark (32°). Elsewhere, scattered showers are returning to the northern High Plains, while a few showers and thunderstorms are affecting the southeastern Plains. The winter wheat harvest is advancing, far ahead of the usual pace, across the southern half of the Plains.
In the South, Tropical Depression Beryl is currently centered near the North Carolina coastline, accelerating toward the northeast. Locally heavy, drought-easing rain continues in the southern Mid-Atlantic region but has largely ended across the lower Southeast. Unfavorably hot, dry weather covers much of the remainder of the region, except for some thunderstorms developing across the Mid-South.
In the West, temperatures are rebounding to near- or above-normal levels, following the recent cool spell. Except for a few showers in western Washington, dry weather favors fieldwork and crop development
"Beryl" may briefly regain tropical-storm status later Wednesday while accelerating away from the U.S. mainland. Rain associated with Beryl will gradually end in the Mid-Atlantic coastal plain.
Meanwhile, a developing storm over the nation’s mid-section will drift northeastward, reaching New England by week’s end. Storm-total rainfall could reach 1 to 3 inches, with locally higher amounts, along and near the path of the storm from the southern Plains into the Northeast.
In the West, mostly dry weather will accompany a return to hot weather. In contrast, late-week frost could affect portions of the upper Midwest and upper Great Lakes States.
Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures and near- to below-normal rainfall across the majority of the U.S. Cooler-than-normal conditions will be confined to the northern Rockies and areas along the Pacific Coast, while wetter-than-normal weather will be limited to the Northeast and the Pacific Northwest.
