In the West, 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. In addition, dry thunderstorms could spark new wildfires and produce gusty winds in the vicinity of existing fires.

On the Plains, 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. Isolated thundershowers are confined to the northern half of the Plains.

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. 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.

In the South, 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.

Outlook: 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. Meanwhile, 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. Scattered showers will dot the Southwest, but mostly dry weather will prevail across the southern Plains and the Far West. The NWS 6- to 10-day outlook for July 13-17 calls for near- to above-normal temperatures and precipitation across the majority of the nation. Cooler-than-normal conditions will be confined to the Southeast, while drier-than-normal weather will be limited to the Northwest.
