In the West, wildfire activity remains a threat in some areas, particularly across southern California, where the Station fire has charred more than 100,000 acres of vegetation. Meanwhile in the Southwest, isolated showers are developing well in advance of the approach of eastern Pacific Hurricane Jimena.

On the Plains, dry weather favors fieldwork, including spring wheat harvesting across northern areas. Warmth is expanding eastward across the High Plains, promoting summer crop maturation.

In the Corn Belt, unusually cool weather is maintaining concerns with respect to developmentally delayed corn and soybeans. Early this morning, scattered frost was confined to the Great Lakes region, north of the primary crop region.

In the South, scattered showers continue in the vicinity of a stalled frontal boundary stretching from Florida to southern Texas. Rainfall is especially beneficial in southern Texas, where much more rain is needed to significantly ease the effects of a two-year drought and a summer-long heat wave.

Outlook: Moisture associated with Hurricane Jimena will gradually spread as far north as the southwestern U.S., contributing to an increase in shower activity. Meanwhile, isolated showers and thunderstorms will develop at mid-week across the eastern Plains and spread into the Mid-South. Farther east, mostly dry weather will prevail from the Midwest into the Northeast, accompanied by a gradual warming trend. Showers will linger, however, along and near the southern Atlantic Coast. Elsewhere, cooler, showery weather will arrive by week’s end in the Pacific Northwest. The NWS 6- to 10-day outlook for September 6-10 calls for above normal temperatures in southern Florida, the south-central U.S., and from the Great Lakes region into the Northeast, while cooler-than-normal conditions will prevail in the Northwest and much of the Southeast. Meanwhile, drier-than-normal weather in New England will contrast with near- to above-normal precipitation across the remainder of the U.S.
