In the Corn Belt, cloudiness increased overnight Thursday, helping to prevent a second freeze. Nevertheless, scattered frost was noted in the Great Lakes region, particularly across Wisconsin and Michigan. Producers continue to monitor the effects of the September 15 freeze on immature corn and soybeans in Minnesota, the eastern Dakotas, northern Iowa, and west-central Wisconsin. A few rain showers are affecting the western Corn Belt.
On the Plains, mild weather is returning to Montana, but chilly conditions linger farther south. Scattered showers continue across the southern Plains, but much more rain is needed to revive pastures and rangeland. In addition, producers on the southern Plains are still awaiting more moisture before widespread planting of winter wheat can begin.
In the South, cool, mostly dry weather continues to promote summer crop maturation and harvesting.Thunderstorms linger in the coastal Carolinas, while a few showers are developing in Arkansas.
In the West, cool weather prevails. Nevertheless, early-autumn fieldwork—such as Northwestern winter wheat planting—is ongoing in most areas, although scattered showers dot the Intermountain West.
Cool weather will linger through the weekend across the eastern U.S., although the threat of additional frost will be confined to the interior Northeast.
By early next week, warmth will temporarily cover much of the U.S. However, chilly weather—but not as cold as the September 14-16 cold snap—will return to the Midwest by the middle of next week.
Meanwhile, a series of weak, fast-moving disturbances will result in scattered showers across much of the country. During the next 5 days, precipitation totals in excess of an inch may occur in the Great Lakes region, the Pacific Northwest, and from the southeastern Plains into the Mid-South.
Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures and near- to below-normal precipitation across most of the nation. Cool weather will be limited to the Southeast, while wet conditions will be confined to the Pacific Northwest and the Northeast.
