In the West, hot, dry weather is promoting fieldwork and crop development, although wildfires remain a threat in parts of the West Coast States. In southern California, active wildfires have consumed more than 50,000 acres of vegetation.

On the Plains, isolated showers are confined to southern portions of the region. Warm weather is returning to the northern Plains, where spring wheat harvesting continues, but chilly conditions linger across the central and southern Plains.

In the Corn Belt, cool, dry weather prevails. Scattered frost—but no freeze—was reported this morning across the upper Midwest, where temperatures dipped below 40 degrees F as far south as northern Iowa.

In the South, scattered showers linger in the southern Atlantic States and in the vicinity of the Gulf Coast. Across the remainder of the region, cool, dry weather favors fieldwork, including harvest activities for crops such as corn and rice.

Outlook: Cool air will shift eastward during the first half of the week, with the threat of scattered frost shifting from the upper Midwest into the Northeast. Meanwhile, showers will linger for much of the week along and near the southern Atlantic Coast. During the second half of the week, scattered thunderstorms will develop across the eastern Plains and spread into the Mid-South. Mostly dry weather will prevail for the remainder of the week in the Midwest, accompanied by a warming trend. Hot weather will continue for much of the week west of the Rockies, although moisture associated with eastern Pacific Hurricane Jimena may contribute to a late-week increase in showers across the Southwest. The NWS 6- to 10-day outlook for September 5-9 calls for below-normal temperatures in the West, while warmer-than-normal weather will prevail across southern Texas and from the Midwest into the Northeast. Meanwhile, above-normal precipitation in the northern Rockies and across the central one-third of the U.S. will contrast with drier-than-normal conditions in northern New England and the Desert Southwest.
