USDA: Foot-plus of Snow in Areas of the Upper Midwest

May 3, 2013 03:47 AM

USDA's Joint Ag Weather Facility says in the Corn Belt, a nearly stationary band of precipitation stretches from the middle Mississippi Valley into the upper Midwest, curtailing fieldwork. "Snow lingers along the western edge of the precipitation shield," USDA adds. On May 1-2, snowfall totaled a foot or more in parts of southeastern Minnesota and northwestern Wisconsin, according to USDA. "In stark contrast, warm, dry weather is accelerating fieldwork in the eastern Corn Belt," USDA adds.

In the West, USDA reports warmth continues to gradually expand eastward from the Pacific Coast states. "Cool conditions linger, however, across the central and southern Rockies," USDA continues. Throughout the West, dry weather favors fieldwork, although drought continues to intensify across the Four Corners region, USDA reports.

On the Plains, USDA says freeze warnings are in effect this morning in many areas from Nebraska to Texas. "On the central and southern High Plains, the latest cold snap is another blow to winter wheat that has already been harmed by drought and multiple spring freezes," USDA explains.

In the South, USDA reports very cool air is overspreading areas west of the Mississippi Delta. Meanwhile, USDA says locally heavy rain continues across the lower Mississippi Valley and portions of the lower Southeast. "The cool, showery weather is limiting fieldwork that has already been significantly delayed in some areas, including the Delta," USDA continues.

In its outlook USDA says a slow-moving storm over the nation’s mid-section will drift east during the next several days. "Because the storm is cut off from atmospheric steering currents, mode rate to heavy rainfall (2-4 inches, locally more) is likely from the Mississippi Valley into the Southeast," USDA continues. In contrast, little or no precipitation will fall during the next five days across the Northeast and Northern Plains, USDA reports. Following today’s freeze on the Plains, temperatures will slowly moderate, USDA adds. "By early next week, warmth will expand across the nation’s northern tier, while clouds and scattered showers increase from California into the central and southern Rockies," USDA explains.
