Heat wave continues on the Plains

Heat wave continues on the Plains

Across 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 Friday’s high temperatures will exceed 90°. In contrast, Friday’s highs will remain below 80° in Michigan and Ohio.

On the Plains, 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. However, in areas with limited soil moisture—including the eastern Dakotas and the southern High Plains—heat is stressing pastures and immature summer crops.

In the South, 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.

In the West, 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.

Looking ahead, 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. 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).

Meanwhile, 5-day precipitation totals could reach 1 to 2 inches, with locally higher amounts, across Florida, the Southwest, and the nation’s northern tier. Heavier rain, possibly up to 4 inches, may occur along the Texas coast. 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.

Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures nationwide, with the greatest likelihood of late-season heat expected across the northern Plains and the West. Meanwhile, below-normal rainfall in parts of the Mid-South and from the Pacific Northwest to the upper Midwest will contrast with wetter-than-normal weather from the Southwest to the central and southern High Plains and in the eastern one-third of the U.S.
