USDA: Hot, Dry Weather Stresses Corn & Soybeans

August 26, 2013 03:40 AM

USDA's Joint Ag Weather Facility says in the Corn Belt, thunderstorms are affecting the Great Lakes region, including Wisconsin and Michigan. "Elsewhere, hot, dry weather is increasing stress on corn and soybeans," USDA adds. "Today’s highs will generally range from 85 to 90°F in the eastern Corn Belt, but will top 95°F in some locations from the Mississippi Valley westward," USDA reports.

In the West, USDA says moisture associated with the remnants of former eastern Pacific Tropical Storm Ivo is streaming northeastward across Arizona, southeastern California, southern Nevada, western Colorado, and Utah, increasing the risk of flooding. "In contrast, dry weather prevails across northern California and the interior Northwest, where approximately three dozen large wildfires are in various stages of containment," USDA continues.

On the Plains, USDA says widely scattered showers are confined to Montana and the Dakotas. Elsewhere, hot, dry weather prevails, USDA adds. "Today’s high temperatures will approach or reach 100°F in many parts of the nation’s mid- section, possibly as far north as eastern Montana," USDA details. On the southern High Plains, hot weather and soil moisture shortages are increasing stress on rangeland, pastur es, and rain-fed summer crops, including cotton, according to USDA.

In the South, favorably drier air has pushed into the southern Atlantic States, except for some lingering showers across southern Florida, USDA reports. Shower activity also lingers along the central and western Gulf Coast, USDA continues.

In its outlook, USDA says heat will dominate the nation’s mid-section, including the Plains and much of the Midwest, for the remainder of the week. "Tropical moisture will maintain the threat of flooding during the next several days in the Southwest, where five-day rainfall totals could reach 1 to 2 inches or more," USDA explains. Meanwhile, showers and thunderstorms will regularly affect the nation’s northern tier, producing 1 to 3 inches of rain—along with local wind and hail damage—from the northern Plains into the Northeast, according to USDA. A few showers will affect the western Gulf Coast region, but dry weather will prevail from California to the northern Rockies and from the central and southern Plains into the middle and lower Mississippi Valley, according to USDA.
