USDA's Joint Ag Weather Facility says in the Corn Belt, cooler weather prevails in the Great Lakes region. "However, hot conditions persist across southern and western portions of the Midwest, including the Missouri and Ohio Valleys," USDA adds. Across the eastern Corn Belt, Wednesday's thundershowers provided only limited and localized drought relief.
In the West, USDA says mostly dry weather favors fieldwork, including initial Northwestern winter wheat harvesting. "Below-normal temperatures in California and the Great Basin contrast with hotter-than-normal conditions in the northern Rockies and the Northwest," USDA reports.
On the Plains, USDA explains searing heat continues to wither pastures and both rain-fed and irrigated summer crops. "On the northern Plains, hot weather is promoting winter wheat harvesting and hastening the maturation of spring-sown small grains," USDA explains. Widespread highs of 100° to 105°F will occur later today on the northern and central Plains, USDA elaborates.
In the South, hot weather prevails, USDA reports. "Drought continues to adversely affect many pastures and summer crops in the Mid-South (e.g., Arkansas), but beneficial showers dot the Southeast," according to USDA.
USDA's outlook says during the next few days, somewhat cooler air will cover roughly the eastern one-third of the U.S. "Widespread showers and thunderstorms will accompany the slightly cooler conditions in the Mid-Atlantic and Southeastern states," USDA reports. Across the central one-third of the U.S., blazing heat and mostly dry conditions will persist, except for some weekend showers in the upper Midwest, according to USDA. "At times, temperatures could approach 110°F across the nation’s mid-section," USDA adds. Elsewhere, USDA says a gradual warming trend will affect much of the West, where isolated showers will be largely confined to the Four Corners States and the Pacific Northwest.
