USDA: Cooler-than-Normal Conditions Across Upper Midwest

July 31, 2013 03:19 AM
 

USDA's Joint Ag Weather Facility says in the Corn Belt, cool weather continues to benefit reproductive to filling summer crops. "Scattered showers dot the eastern Corn Belt and upper Midwest , but pockets of unfavorable dryness persist in the western Corn Belt," states USDA..

In the West, a temporary break in the monsoon continues, says USDA. "In the Northwest , hot, mostly dry weather favors summer crop development and winter wheat maturation and harvesting," it states.

On the Plains, cool conditions linger across Montana and the Dakotas. "In contrast, hot weather prevails in Texas and is expanding toward the central High Plains," it explains.

In the South, showers are arriving, following a brief period of dry weather, USDA says. "However, widespread rain has not yet returned to the southern Atlantic States, where July rainfall records have al ready been set in locations such as Greenville-Spartanburg, South Carolina (14.40 inches), and Asheville, North Carolina (13.44 inches)," it relates.

In its outlook, USDA says a stationary upper-air low centered over Hudson Bay in eastern Canada will maintain cooler-than- normal conditions from the northern Plains into the Corn Belt and Northeast. "In contrast, high pressure will provide hot, dry weather across the south-central U.S.," it says, "with heat gradually expanding into the Southeast." Between these two air masses, a wavy frontal boundary coupled with a series of weak disturbances will trigger locally heavy showers and thunderstorms from the northern High Plains into the central and southern Corn Belt, with some showers falling east of the Appalachians as well, it says. Out west, monsoon showers will resume in the Four Corners region, while dry, seasonably hot weather prevails in California and the Great Basin. Periods of rain, however, are anticipated in the Pacific Northwest and northern Rockies, USDA says.
