Snow storm in rural AmericaTemperatures were in the 60s and 70s in the central U.S. — much warmer than normal for this time of year — on Wednesday, but changes are coming soon, with a low-pressure system moving into the Southwest and pushing rain and snow east from the Rocky Mountains into the Plains and Corn Belt, with parts of Kansas, Nebraska, northern Missouri, Iowa, Illinois, Wisconsin and Michigan expected to see snowfall Friday and Saturday. As that system moves northeast out of the U.S., a second system could deliver more snow to the central Plains, namely parts of Kansas and Oklahoma. Notable dryness will remain in Southern California, the northern Plains and much of the Southeast through the next week, according to the latest forecast. For the next two weeks, long-range models indicate temperatures in the contiguous U.S. will stay seasonable or warmer than normal as cold air masses remain in Canada. Forecasters now are watching La Niña and the likelihood it could begin to weaken heading further into winter. See more from the latest forecast.
