In the West, slightly cooler air is spreading across the Northwest, accompanied by a few showers. Elsewhere, warm, dry weather continues to promote autumn fieldwork.

On the Plains, warm, dry weather is maintaining stress on recently emerged winter wheat. Late-season warmth is especially notable on the High Plains, where today’s temperatures will top 70°F as far north as Montana.

In the Corn Belt, mild air is overspreading westernmost areas, including the middle Missouri Valley. In contrast, cloudy, showery weather is slowing late-season fieldwork in the eastern Corn Belt, especially in Indiana, where 11% of both corn and soybeans had not yet been harvested by November 4.

In the South, warm weather is confined to the western Gulf Coast region. Elsewhere, cool weather, cloudiness, and a few showers are limiting harvest activities and other autumn fieldwork.

Outlook: A developing nor’easter currently centered just east of Virginia will lurk near the Mid-Atlantic Coast through Thursday before drifting eastward. With power still out—more than a week after Hurricane Sandy struck— to nearly a million customers, mostly in New Jersey and New York, the new coastal storm could result in a significant setback to recovery operations. Primary impacts from the nor’easter will include high winds and heavy surf, along with 1 to 2 inches of rain. Precipitation will end as snow in parts of the Mid-Atlantic coastal plain. Farther west, a late-week pattern change will result in sharply colder conditions. During the weekend, below-normal temperatures can be expected from the Pacific Coast to the Plains, while temperatures will rebound to above-normal levels in the East. Widespread precipitation, including some heavy snow, will precede and accompany the colder weather from the Pacific Northwest to the northern Plains. In addition, showers and thunderstorms will erupt during the weekend from the upper Great Lakes region to the southeastern Plains. The NWS 6- to 10-day outlook for November 12-16 calls for near- to above-normal temperatures and precipitation across much of the nation. However, cooler-than-normal conditions will prevail from the Pacific Northwest into the upper Midwest, while drier-than-normal weather will stretch from southern California to the central and southern High Plains.
