USDA's Joint Ag Weather Facility says in the Corn Belt, mild, dry weather continues to promote corn and soybean maturation, early-season harvest activities and initial winter wheat planting efforts.
In the West, USDA reports rain and snow showers linger across the Intermountain region and northern Rockies. "The coldest air of the season has led to freeze warnings for early today in parts of the Great Basin and neighboring areas," USDA reports.
On the Plains, USDA says a few rain showers are breaking out across northern areas in conjunction with a strong cold front. In the front's wake, sharply colder air is overspreading the northern Plains, USDA adds. Elsewhere, dry weather and late-season warmth are ideal for summer crop maturation and harvesting, as well as winter wheat planting, according to USDA.
In the South, USDA reports isolated showers are confined to the immediate southern Atlantic Coast. "Elsewhere, mild, dry weather favors summer crop maturation and fieldwork, including harvest activities in the Mississippi Delta that had been delayed by last week's torrential rainfall," USDA continues.
In its outlook USDA says a slow-moving cold front currently extends from the Four Corners region into the upper Midwest, separating late-season warmth over the central and eastern U.S. from sharply colder weather in the West. "Behind the front, an upper-air disturbance will maintain periods of snow across the northern Rockies through today, while increasingly heavy showers will develop during the weekend over the Plains and Mississippi Valley," USDA details. However, the front will dissipate as it drifts east, resulting in diminishing showers east of the Mississippi, with little — if any — rain expected east of the Appalachians, USDA continues. "Behind the front, a rapid warm up will ensue over the northern Plains, with daytime highs expected to average 10 to 20°F above normal by Sunday," USDA reports. In contrast, USDA says cold, stormy weather will prevail in the Northwest, with an abundance of Pacific moisture contributing to heavy rain and mountain snow.
