A Bermuda High will maintain increasingly hot, humid conditions across much of the eastern U.S., with temperatures averaging up to 10°F above normal from the central Plains and Corn Belt to the Atlantic Coast States, according to USDA’s agricultural weather highlights.
Scattered showers are likely in the afternoon heat, though no large organized areas of rain are expected from the central and southern Plains into the Southeast. Farther north, a cold front will drift southward out of Canada, generating locally heavy showers and thunderstorms from the Great Lakes and Corn Belt into the Mid-Atlantic during the latter half of the week.
Meanwhile, chilly weather associated with a pronounced southward dip in the jet stream over the western U.S. will give way to warmer conditions by week’s end, while a departing storm produces additional rain and mountain snow over northern portions of the Rockies and High Plains.
The National Weather Service 6- to 10-day outlook for June 22-26 calls for above-normal rainfall east of the Mississippi to contrast with near- to below-normal precipitation across the central and western U.S. Above-normal temperatures are expected across much of the nation, with cooler-than-normal weather confined to southern portions of the Rockies and Plains into west Texas.

Regional Weather Forecasts
In the West, rain and high elevation snow are boosting moisture reserves across northern portions of the Rockies and Intermountain region, while drought continues to impact pastures, crops, and water reserves from California into the Four Corners region.
On the Plains, mostly dry weather is promoting fieldwork and crop development. Long-term drought persists in key central and southern winter wheat areas, though recent rain has improved summer crop prospects. For example, 63 percent of Kansas’ winter wheat was rated poor to very poor as of June 15, while the state’s corn crop was only 9 percent poor to very poor (and 50 percent good to excellent).
In the Corn Belt, locally heavy showers and thunderstorms are easing soil moisture deficits in Iowa and northern Illinois. Elsewhere, dry, warm weather is promoting corn and soybean development.
In the South, mostly dry weather is promoting winter wheat harvesting and other seasonal fieldwork after recent rain-induced delays. Seasonal showers continue to ease dryness in southern Florida.
