In the West, unusually cool weather prevails in California, while monsoon shower activity has temporarily subsided in the Four Corners States. Farther north, isolated showers are developing across the interior Northwest, although conditions remain generally conducive for the ignition or spreading of wildfires.

On the Plains, flash flooding remains a threat in portions of northern Oklahoma and south-central and southeastern Kansas. Elsewhere, showers are causing minor fieldwork disruptions on the northern Plains, while hot weather across much of Texas is maintaining stress on rangeland, pastures, and rain-fed summer crops.

In the Corn Belt, most areas are experiencing cool, dry weather. Near- to below-normal temperatures remain ideal for corn and soybeans, although a broad area centered on Iowa needs rain to stabilize crop prospects. Among Midwestern States, Missouri (20%) and Iowa (17%) had the greatest percentage of corn rated in very poor to poor condition on August 4.

In the South, portions of the Ozark Plateau remain at risk for additional flooding, as rain returns to the region. In contrast, hot, mostly dry weather prevails from the western Gulf Coast region into the Southeast.

Outlook: Today will be the final day of potential heavy rain from the central Plains into the Mid-Atlantic and Northeastern States. During the weekend, heavier shower activity will shift into the Southeast. Five-day rainfall totals could reach 1 to 3 inches from the Mid-South into the Southeast. During the first half of next week, cool, mostly dry weather will dominate the Midwest and Northeast, while hot conditions will persist across the Deep South and interior Northwest. The NWS 6- to 10-day outlook for August 14-18 calls for above-normal precipitation across the Plains, Mid-South, and Southeast, while drier-than-normal weather will prevail in the Rio Grande Valley, Southwest, and from the Great Lakes region into New England. Meanwhile, above-normal temperatures across the Deep South and much of the West will contrast with cooler-than-normal conditions across most of the eastern half of the U.S. and along the Pacific Coast.
