USDA's Joint Ag Weather Facility says in the Corn Belt, lowland flooding continues to gradually subside in waterlogged portions of Iowa, Minnesota and Wisconsin. Scattered frost and temperatures locally below 35°F were noted this morning in the western Corn Belt, mainly in Nebraska and the eastern Dakotas. Meanwhile, cool, cloudy weather and scattered showers are halting fieldwork in the eastern Corn Belt.
In the South, USDA reports heavy showers continue to result in local flooding and widespread fieldwork delays in the southern Mid-Atlantic States. Elsewhere, dry weather is promoting summer crop maturation and harvesting, but curtailing grass growth and increasing supplemental feeding requirements for livestock.
On the Plains, dry weather is ideal for winter wheat planting and summer crop maturation and harvesting, USDA says.
In the West, a plume of moisture associated with the remnants of Tropical Storm Roslyn is sparking a few showers in the Great Basin and the Southwest. Elsewhere, very warm, dry weather continues to favor fieldwork, including summer crop harvesting and winter wheat planting, USDA states.
In its outlook, USDA says a nearly stationary storm system centered over the Ohio Valley will drift northward into the Great Lakes region during the weekend. The threat for heavy rain and local flooding will persist into Friday across the Mid-Atlantic region, followed by a gradual shift in shower activity — along with diminishing intensity — into the Great Lakes and Northeastern States. Additional rainfall could locally reach 2 to 6 inches in the Mid-Atlantic States. Dry weather will cover the remainder of the U.S., except for showers (locally 1 to 2 inches) in the Pacific Northwest and from the Four Corners States to northern sections of the Rockies and High Plains. Much cooler air will arrive in the Far West during the weekend and spread across the High Plains early next week. Meanwhile, warmth will expand across the central and eastern U.S., USDA reports.
