USDA's Joint Ag Weather Facility says in the Corn Belt, cooler, drier conditions prevail in most areas following the passage of a slow-moving cold front. Morning showers are generally confined to the Ohio Valley.
In the South, tropical showers will intensify through the day over western sections of the Florida Peninsula, USDA reports. Elsewhere in the region, warm, mostly dry weather supports maturation and early harvesting of summer crops, though light showers will fall ahead of a slow-moving cold front.
On the Plains, USDA says lingering, scattered showers are providing a late-season boost in moisture to sorghum and other immature summer crops in the south, while providing an additional boost in long-term moisture reserves for the upcoming hard red winter wheat crop. In contrast, conditions mostly favor spring wheat harvesting in the north.
In the West, USDA notes warm, dry, and breezy conditions maintain a high risk of wildfire activity across a large area centered over the Great Basin and central Rockies; otherwise, conditions favor maturation of California’s cotton and rice and support spring wheat harvesting in the Northwest.
In its outlook, USDA says Tropical Storm Hermine is expected to make landfall overnight in northern Florida, with sustained winds near hurricane strength (74 mph or higher). The forecast track, which has greatly fluctuated over the past few days, now takes the center of the storm inland from southern Georgia to the Carolina Coast. This path would generate untimely wind and rain for maturing cotton, with expected rainfall totaling 5 to 10 inches. Meanwhile, drier, generally cooler weather will prevail for the remainder of the week in the Midwest and interior Southeast, aiding summer crop maturation supporting autumn fieldwork, including harvesting of rice in the Deep South. Dry weather is also expected along the West Coast. As rainfall diminishes in the Southwest, scattered showers will redevelop over the central and northern Rockies, USDA says.
