In the West, generally cool weather prevails from California to the central Rockies. In contrast, hot, dry weather favors fieldwork, including winter wheat harvesting, across the interior Northwest.
On the Plains, heavy rain in Kansas separates cool, dry conditions across northern areas and hot, dry weather in Texas and southern Oklahoma. Once again, today’s temperatures will generally exceed 100°F on the southern Plains, maintaining stress on rangeland, pastures, and rain-fed summer crops. Farther north, flooding remains a concern in parts of Kansas, while winter wheat harvesting is proceeding on the northern Plains.
In the Corn Belt, near- to below-normal temperatures are favorable for reproductive to filling summer crops, although pockets of dryness remain a concern. During the last two month, the greatest precipitation deficits— locally in excess of 6 inches—have accumulated across Iowa (excluding the northeast) and northern Missouri.
In the South, flash flooding is occurring in the Ozarks, including portions of southern Missouri and northwestern Arkansas. In contrast, very hot, dry weather prevails from the western Gulf Coast region to the Delta.
Outlook: Areas from the central Plains to the northern Mid-Atlantic region will remain the focus of heavy showers through Friday, with an additional 2 to 4 inches of rain possible. Drier weather will arrive across the central Plains and the Northeast on Saturday, although showers will linger in the Southeast. By early next week, heavy showers may return to the central Plains. Occasional showers will affect most other parts of the U.S., although 5- day rainfall totals will be mostly an inch or less. Elsewhere, pleasantly cool weather across the northern and central Plains and the Midwest will contrast with hot conditions across the interior Northwest and the Deep South. The NWS 6- to 10-day outlook for August 13-17 calls for below-normal temperatures from the Midwest into the Northeastern and Mid-Atlantic States, while hotter-than-normal weather will prevail across the interior Northwest and the nation’s southern tier. Meanwhile, near- to above-normal rainfall across the majority of the U.S. will contrast with drier-than-normal conditions in southern and western Texas, the Southwest, and the upper Great Lakes region.
