USDA: A Weak Cold Front to Bring Showers to Eastern Corn Belt

July 18, 2012 03:11 AM

USDA's Joint Ag Weather Facility says on the Plains, extremely hot weather is maintaining severe stress on pastures and summer crops, especially across central portions of the region. "Today's high temperatures will generally range from 100° to 105°F on the central Plains, but cooler air and some thundershowers continue to overspread the Dakotas," USDA elaborates.

In the West, USDA says unusually warm weather is confined to the interior Northwest, where the winter wheat harvest is just getting underway. "Elsewhere, mostly dry weather accompanies below-normal temperatures," USDA reports.

In the Corn Belt, USDA says heat and drought continue to reduce yield and production potential for corn and soybeans. "Today's high temperatures will again approach or reach 100°F in the southern Corn Belt," USDA adds. Somewhat cooler air is beginning to overspread the northern tier of the Corn Belt, accompanied by a few thundershowers, according to USDA.

In the South, USDA reports beneficial showers are occurring in several areas, including southern Texas and the Southeast. "However, drought continues to adversely affect pastures and summer crops in the Mid-South," USDA adds. On July 15, for example, nearly all of the pastures were rated very poor to poor in Missouri (92%) and Arkansas (83%), USDA elaborates.

In its outlook, USDA says during the second half of the week, a weak cold front will cross the eastern Corn Belt and the Mid-Atlantic states. "Rainfall associated with the cold front’s passage could reach 1 to 2 inches in parts of Indiana and Ohio," USDA explains. More substantial showers will affect the Southeast, where widespread 1- to 3-inch totals can be expected, according to USDA. Farther west, however, USDA says extreme heat and dry conditions will persist into next week across the central Plains and neighboring regions, where high temperatures may approach 110°F at times. "Elsewhere, temperatures will gradually rebound to near-normal levels in the West, accompanied by a few showers in the Southwest and Pacific Northwest," USDA reports.
