USDA's Joint Ag Weather Facility says in the Corn Belt, showers and thunderstorms in the vicinity of a strong cold front stretch from near Lake Erie into Missouri. "The rain is slowing corn and soybean harvesting but providing additional moisture for newly planted winter wheat," USDA reports. Meanwhile, sharply colder weather in the front's wake has resulted in freezes this morning throughout the Dakotas, much of Minnesota and Nebraska and northern Iowa, according to USDA.
In the West, USDA says warmth lingers across the southern half of the region, but much colder air has invaded the interior Northwest. "Developing drought remains a concern with respect to rain-fed winter grains in the Northwest," USDA explains.
On the Plains, USDA reports a few rain and snow showers are affecting central portions of the region. "Markedly colder weather is slowing winter wheat emergence, which has already been hampered by extremely dry conditions across the northwestern half of the Plains," USDA explains.
In the South, warm, mostly dry weather favors summer crop harvesting and other fieldwork, USDA says. "Isolated showers are confined to the lower Southeast," USDA adds.
USDA's outlook says the coldest air of the season will continue to overspread much of the nation, with weekend freezes expected across much of the Plains and Midwest. "Meanwhile, lingering warmth will be limited to the Pacific Northwest, the Desert Southwest, and the lower Southeast," USDA explains. Widespread showers will accompany the surge of cold air into the South and East; event-total rainfall could exceed an inch in a few locations from the Mid-South into the Northeast, according to USDA. In the front’s wake, most of the U.S. will experience cool, dry weather, although some light rain and snow may develop across the northern Plains and the Midwest during the first half of next week, USDA explains.
