USDA: Late-Season Heat Expected for Upper Midwest

September 3, 2013 03:40 AM

USDA's Joint Ag Weather Facility says in the Corn Belt, dry weather prevails. "Cooler weather in the eastern Corn Belt contrasts with the return of heat in the far upper Midwest," USDA explains. Recent rainfall has stabilized crop conditions in some corn and soybean production areas of the northern and eastern Corn Belt, but the remainder of the Midwest remains unfavorably dry, according to USDA.

In the West, USDA reports a robust monsoon circulation, which includes remnant moisture associated with former Tropical Storm Kiko, is producing scattered showers. "A low-pressure system centered west of Washington and Oregon is helping to draw moisture into the Northwest, aiding wildfire containment efforts," USDA elaborates.

On the Plains, USDA explains widely scattered showers are primarily confined to western sections of Nebraska and the Dakotas. "Hot weather prevails throughout the region, with t oday’s high temperatures expected to range from 90 to 100°F in many locations," USDA details. The extended spell of hot, mostly dry weather has favored fieldwork and crop maturation, but has stressed rangeland, pastures and rain-fed crops in areas with limited soil moisture reserves, according to USDA.

In the South, USDA says showers are returning to the southern Atlantic states, following a period of favorably dry weather.

In its outlook, USDA says a period of cool, dry weather is in store for the eastern Corn Belt and the Northeast, while late-season heat will prevail across most of the remainder of the U.S. "Scattered readings below 40°F can be expected during the mid- to late-week period from the Great Lakes region to the interior Northeast," USDA explains. In contrast, USDA says persistent and unusual late-season heat will cover the northern and central Plains and far upper Midwest, where late-week temperatures could approach or reach 100°F in a few locations. "Meanwhile, dry weather will prevail through week’s end from the central and southern Plains to the Mid-Atlantic states," USDA continues. A few showers will dot the nation’s northern tier, except in the Northwest, where five-day rainfall totals could reach 1 to 3 inches, according to USDA. "Similarly, scattered showers will affect the Southwest, while 1- to 2-inch amounts can be expected in the Gulf Coast region and along the southern Atlantic Coast," USDA explains.
