USDA's Joint Ag Weather Facility says in the Corn Belt, showers and thunderstorms extend along a cold front from the Great Lakes region into the middle Mississippi Valley. "The rain is slowing initial harvest efforts but easing dry conditions and providing beneficial moisture in advance of winter wheat planting," USDA reports. Cooler air trails the front into the western Corn Belt, USDA adds.
In the West, USDA says mostly dry weather accompanies late-season warmth. "Conditions are mostly favorable for Northwestern winter wheat planting and other fieldwork," USDA explains.
On the Plains, USDA says cooler weather prevails in the wake of a cold front’s passage, except for a rapid return to warmth on Montana’s High Plains. "Showers and thunderstorms linger across the southeastern Plains, while many other parts of the nation’s mid-section are benefiting from recent soil moisture improvements," USDA explains.
In the South, USDA says showers and thunderstorms are gradually overspreading areas west of the Mississippi Delta, providing local drought relief. "In the Southeast, warm, dry weather favors crop maturation and harvesting," USDA continues.
In its outlook USDA says a cold front currently stretching from Texas to Wisconsin will generate showers and thunderstorms as it treks toward the Atlantic Coast. "Tropical moisture associated with the remnants of Hurricane Manuel will enhance rainfall rates on the tail end of the front, with heavy downpours (2-5", locally more) possible from east-central Texas into the Delta," USDA reports. As the southern end of the front stalls, USDA says there is a possibility a new tropical disturbance may form over the northern Gulf. "Farther north, cooler conditions will follow the front’s passage, with some frost possible in the upper Midwest," USDA continues. However, a rapid warming trend will ensue, as above-normal temperatures spread from the northern Rockies into the Corn Belt by early next week, according to USDA. Meanwhile, USDA reports sharply cooler weather will arrive west of the Rockies, with locally heavy showers possible in the Northwest.
