In the West, relatively cool weather accompanies scattered showers in the Desert Southwest, including parts of southern California. Meanwhile, hot, dry weather across the interior Northwest is promoting rapid summer crop development and winter wheat maturation and harvesting.
On the Plains, cooler air is surging into the Dakotas and eastern Montana. Meanwhile on the central Plains, scattered showers and thunderstorms are providing additional relief from short-term dryness, although hot weather is maintaining heavy irrigation demands. Following last week’s drought relief, dry weather has returned to the southern Plains.
In the Corn Belt, scattered showers and thunderstorms are maintaining generally favorable conditions for corn and soybeans. However, short-term dryness is increasing stress on reproductive summer crops in some areas, including much of Iowa, northern parts of Illinois and Missouri, and eastern Nebraska.
In the South, warm, humid, showery weather prevails. Currently, some of the heaviest showers are spreading into the Mid-South, which in recent days has received highly beneficial relief from short-term drought.
Outlook: An active weather pattern will continue for the remainder of the week, particularly across the southern and eastern U.S. Five-day rainfall totals could reach 2 to 4 inches from the central Plains into the Mid-South and Southeast, while 1- to 2-inch amounts will be common from the Ohio Valley into the Northeast. In contrast, little or no rain will fall in the Northwest and the western Gulf Coast region. Meanwhile, a surge of cooler air will overspread the Midwest and Northeast, but hot weather will persist through week’s end across the Northwest and Deep South. The NWS 6- to 10-day outlook for July 27-31 calls for below-normal temperatures in the Pacific Northwest and from the Midwest into the Northeast, while warmer-than-normal weather will prevail from California to the lower Mississippi Valley. Meanwhile, below-normal rainfall in the Pacific Coast States, southern Texas, and much of the Midwest will contrast with wetter-than-normal conditions across the northern and southern Plains, the Mid-South, and the eastern U.S.
