USDA's Joint Ag Weather Facility says on the Plains, late-season heat has returned, following a brief spell of cooler weather. "Today's high temperatures will approach 100°F as far north as South Dakota," USDA adds. Hot weather and significant soil moisture shortages are making some producers reluctant to move ahead with winter wheat planting preparations, USDA reports.
In the West, USDA says a late-season surge of monsoon moisture is resulting in an increase in showers in the Desert Southwest. "Elsewhere, mostly dry weather favors fieldwork, although cooler air is overspreading the Pacific Northwest," according to USDA.
In the Corn Belt, cool, dry weather prevails in the wake of recent rainfall, USDA reports. "Drought-easing rainfall was heaviest across central and southern Indiana, where late-week and weekend precipitation totaled 4 inches or more in many locations," USDA elaborates. Meanwhile, breezy conditions are developing across the upper Midwest, signaling the imminent return of warm weather, USDA explains.
In the South, USDA says mild, dry weather prevails, except for isolated showers across Florida's peninsula. "Dry weather is promoting an acceleration of fieldwork — including summer crop harvesting — in the Southeast, following recent heavy rainfall," USDA elaborates.
In its outlook, USDA says warm weather will soon return to the Midwest, South and East, but another surge of cool air will arrive across the Plains and upper Midwest by Sept. 12-13. "By week’s end, the weather pattern will repeat, with cooler conditions spreading across the Midwest, South and East, and warmth returning to the northern Plains and upper Midwest," USDA reports. Meanwhile, USDA says a surge of monsoon-related moisture will be drawn across the central and southern Plains and parts of the Midwest in advance of a cold front. "Five-day rainfall totals could reach 1 to 2 inches, with locally higher amounts, from the Southwest into the Great Lakes region," USDA elaborates.
