USDA's Joint Ag Weather Facility says in the Corn Belt, mostly dry conditions are maintaining stress on immature corn and soybeans. "In addition, heat is returning to the western Corn Belt, where today’s high temperatures will exceed 90°F," USDA continues. In contrast, today’s highs will remain below 80°F in Michigan and Ohio, USDA details.
In the West, USDA reports significant rain is falling in parts of the Pacific Northwest, where cooler air is arriving. Isolated showers dot the remainder of the Northwest. Elsewhere, hot, mostly dry weather prevails.
On the Plains, USDA reports scattered showers and thunderstorms are mostly confined to the northern tier of the region, including eastern Montana and western North Dakota. "Throughout the region, hot weather is promoting summer crop maturation and harvesting," USDA continues. However, in areas with limited soil moisture—including the eastern Dakotas and the southern High Plains—heat is stressing pastures and immature summer crops, according to USDA.
In the South, USDA says isolated showers are confined to Florida’s peninsula and areas along the Gulf Coast. "Elsewhere, very warm, dry weather favors summer crop maturation and harvesting, although drought is an ongoing concern in the western Gulf Coast region and an emerging concern in parts of the lower Mississippi Valley," USDA explains.
In its outlook USDA says a late-season heat wave will continue into next week across the majority of the nation. "The core region of unusual heat will remain focused across the Plains during the weekend but will briefly shift into the Midwest early next week," USDA reports. Cooler-than-normal conditions will be mostly limited to the lower Great Lakes region and New England (during the weekend), and the Southwest (early next week), USDA elaborates. Meanwhile, five-day precipitation totals could reach 1 to 2 inches, with locally higher amounts, across Florida, the Southwest, and the nation’s northern tier, USDA adds. "Heavier rain, possibly up to 4 inches, may occur along the Texas coast," USDA continues. In contrast, only light showers can be expected in the Corn Belt, while dry weather will persist from the southern Plains to the lower Mississippi Valley, USDA explains.
