USDA's Joint Ag Weather Facility says in the Corn Belt, a line of showers and thunderstorms stretches from Michigan to northern Missouri. "The rain is maintaining abundant moisture reserves for corn and soybeans," USDA adds. Midwestern temperatures remain mostly favorable for developing summer crops, although a brief surge of heat will boost today’s temperatures above 90°F in the southwestern Corn Belt, according to USDA.
In the West, USDA says isolated showers associated with the monsoon circulation are providing local drought relief in the Four Corners states. "However, much of the West continues to experience hot, dry conditions," USDA continues. In addition, dry thunderstorms could spark new wildfires and produce gus ty winds in the vicinity of existing fires, according to USDA
On the Plains, USDA reports hot weather prevails, except along the Canadian border. Today’s high temperatures will exceed 100°F as far north as the central Plains, hastening the winter wheat harvest but boosting irrigation demands, USDA explains. "Isolated thundershowers are confined to the northern half of the Plains," USDA continues.
In the South, USDA reports showers are becoming more numerous in the western Gulf Coast region, providing local relief from recent heat and dryness. "In contrast, shower activity has become more scattered in the Southeast, following last week’s deluge," USDA reports.
In its outlook, USDA says during the next several days, a surge of cooler air will briefly affect the northern Plains before settling across the Midwest. "Very hot weather will persist all week on the southern Plains and return during the second half of the week to the remainder of the nation’s mid-section," USDA reports. Meanwhile, USDA says early-week heat in the West will be gradually replaced by somewhat cooler conditions. "Five-day rainfall totals could reach 1 to 3 inches in the East and 1 to 2 inches across portions of the northern Plains and Midwest," USDA details. Scattered showers will dot the Southwest, but mostly dry weather will prevail across the southern Plains and the Far West, according to USDA.
