In the West, a temporary break in the monsoon continues. In the Northwest, hot, mostly dry weather favors summer crop development and winter wheat maturation and harvesting.
On the Plains, cool conditions linger across Montana and the Dakotas. In contrast, hot weather prevails in Texas and is expanding toward the central High Plains. Rangeland, pasture, and crop conditions remain mixed.
In the Corn Belt, cool weather continues to benefit reproductive to filling summer crops. Scattered showers dot the eastern Corn Belt and upper Midwest, but pockets of unfavorable dryness persist in the western Corn Belt. On July 28, Missouri led the U.S. with 17% of its soybeans rated in very poor to poor condition.
In the South, showers are arriving, following a brief period of dry weather. However, widespread rain has not yet returned to the southern Atlantic States, where July rainfall records have already been set in locations such as Greenville-Spartanburg, South Carolina (14.40 inches), and Asheville, North Carolina (13.44 inches).
Outlook: A stationary upper-air low centered over Hudson Bay in eastern Canada will maintain cooler-thannormal conditions from the northern Plains into the Corn Belt and Northeast. In contrast, high pressure will provide hot, dry weather across the south-central U.S., with heat gradually expanding into the Southeast. Between these two air masses, a wavy frontal boundary coupled with a series of weak disturbances will trigger locally heavy showers and thunderstorms from the northern High Plains into the central and southern Corn Belt, with some showers falling east of the Appalachians as well. Out west, monsoon showers will resume in the Four Corners region, while dry, seasonably hot weather prevails in California and the Great Basin. Periods of rain, however, are anticipated in the Pacific Northwest and northern Rockies. The NWS 6- to 10-day outlook for August 5-9 calls for below-normal temperatures from the northern Plains to the central and northern Atlantic Coast, with hotter-thannormal weather confined to the Pacific Northwest and from southern New Mexico to the central Gulf Coast. Wetter-than-normal weather is anticipated across much of the contiguous U.S. east of the Rockies, except for southern Texas, while drier-than-normal conditions are expected west of the Rockies.
