In the West, a resumption of the monsoon is providing much-needed moisture to drought-stricken areas of the Four Corners region. Showers have also returned to the Northwest, slowing winter wheat maturation and harvesting. Elsewhere, dry, cooler-than-normal weather is promoting summer crop development and fieldwork.

On the Plains, showers and thunderstorms along a stationary frontal boundary are providing drought relief from South Dakota into Kansas and Oklahoma. Below-normal temperatures over the northern Plains are contrasting with 100-degree heat across southern portions of the region.

In the Corn Belt, cool weather continues to benefit reproductive to filling summer crops. Showers in the

In the South, dry, increasingly warm weather is following yesterday’s rain. Soil moisture remains adequate to locally excessive for pastures and summer crops after a record-wet July in portions of the region.

Outlook: Over the weekend, showers will accompany a cold front as it pushes slowly southeast across the eastern third of the nation. Meanwhile, a stationary upper-air low in eastern Canada will maintain well-below-normal temperatures from the northern Plains into the Corn Belt and Northeast. In contrast, a ridge of high pressure will provide hot, dry weather across the southern Plains and western Delta. Between these two air masses, a frontal boundary coupled with a series of weak disturbances will generate periods of rain (locally more than 2 inches) from the central Plains into the western and southern Corn Belt. Out west, monsoon showers will persist in eastern portions of the Four Corners region, while sunny skies and seasonably hot weather continue in California and the Great Basin. The NWS 6- to 10-day outlook for August 7-11 calls for near- to above-normal rainfall across much of the contiguous U.S., with drier-than-normal conditions confined to the western Gulf Coast, southern Great Basin, and upper Great Lakes region. Cooler-than-normal weather will continue to dominate a large section of the country from the northern and central Plains to New England, including the Corn Belt. Meanwhile, above-normal temperatures are expected in the Northwest and from the Rio Grande Valley into the southern Delta.
