USDA's Joint Ag Weather Facility says in the Corn Belt, unusually cool weather in the upper Midwest contrasts with lingering warmth farther east. "Fieldwork remains at a virtual standstill in the western Corn Belt due to waterlogged fields and ongoing rain, while showers are slowing a previously rapid planting pace in the eastern Corn Belt," USDA explains.
In the West, USDA reports warmth continues to expand across California and the Southwest, but very cool conditions persist in the northern Rockies and northern Intermountain West.
On the Plains, USDA says cool, rainy weather continues to impede spring wheat planting and other fieldwork in Montana and the Dakotas. "Farther south, showers and thunderstorms linger across the eastern Plains, following yesterday’s severe weather outbreak," USDA continues. In contrast, hot, dry weather on the southern High Plains is promoting winter wheat maturation but maintaining stress on rangeland, pastures and emerging summer crops, according to USDA.
In the South, USDA says warm, dry weather continues to promote fieldwork in the southern Atlantic States, except in rain- soaked southern Florida. "West of the Appalachians, increasingly showery weather is gradually closing a window of open weather that had allowed producers to make rapid progress in planting summer crops," USDA continues.
In its outlook USDA says a slow-moving storm system currently centered over the upper Midwest will drift eastward across the nation’s northern tier, reaching the Great Lakes region by Sunday. "As the storm moves eastward, heavy rain will slowly subside across the northern Plains and western Corn Belt, although lowland flooding will persist for several days," USDA continues. The storm’s trailing cold front, which will reach the Atlantic Seaboard by June 3, will remain the focus for locally severe thunderstorms, USDA details. Cooler air will trail the cold front across the Plains and Midwest, it adds. "During the weekend, heat will build in the Pacific Coast States and quickly spread eastward, reaching the southern High Plains early next week," USDA reports. Elsewhere, mostly dry weather will prevail during the next five days west of the Rockies, while heavy showers will persist across Florida’s peninsula, according to USDA.
