A pattern change ahead
Across the Corn Belt, cool, dry weather across the majority of the region favors late-season fieldwork. However, rain showers associated with a developing storm are spreading across the southwestern Corn Belt, including the middle Mississippi and lower Missouri Valleys.
On the Plains, cool conditions linger across eastern portions of Kansas, Nebraska, and the Dakotas. Meanwhile, mild weather is returning to the High Plains, where Monday’s high temperatures will approach 70° as far north as Montana. Despite the late-season warmth, additional moisture is still needed in many areas to promote further winter wheat development.
In the South, a few rain showers are overspreading the northwestern fringe of the region, including northern Arkansas. Elsewhere, dry weather is promoting autumn fieldwork, including winter wheat planting and cotton, peanut, and soybean harvesting. Producers in the southern Mid-Atlantic States continue to assess the impacts of Hurricane Sandy’s wind and rain on unharvested crops.
In the West, isolated showers are confined to western sections of Washington and Oregon. Elsewhere, dry, unusually warm weather favors fieldwork, including cotton harvesting in Arizona and California.
A storm currently crossing the middle Mississippi Valley will intensify near the Mid-Atlantic coast on Tuesday night and Wednesday. By Thursday, a powerful “nor’easter” will be located near the New England coast. Potential storm effects along the northern Atlantic Coast will include 1 to 3 inches of rain, high winds, and pounding surf. Fragile oceanfront areas affected by Hurricane Sandy will be especially vulnerable to additional
Meanwhile, a weather pattern change will get underway in the West. By Thursday, notably cooler air will arrive in the Pacific Coast States and the northern High Plains. During the weekend, below-normal temperatures will prevail from the Pacific Coast to the Plains, while warmer-than-normal weather will overspread the East. Widespread precipitation, including some heavy snow, will precede and accompany the Western surge of cold air.
Looking ahead, the 6- to 10-day outlook calls for below-normal temperatures across the Plains, West, and upper Midwest, while warmer-than-normal weather will prevail in the South, East, and lower Midwest. Meanwhile, above-normal precipitation across the majority of the U.S. will contrast with drier-than-normal conditions in the Northwest, the southern Atlantic region, and southern portions of the Rockies and High Plains.
