Parts of Utah, Wyoming, and Colorado are covered in 3 feet of snow as an autumn snowstorm slowly makes its way into Nebraska and Kansas.
The system shuttered schools, caused dozens of traffic accidents and canceled about 200 flights.
The weather service is warning of near-zero visibility on roads in eastern Colorado. And huge stretches of interstates in Wyoming were shut down.
A winter storm warning is in effect for portions of Nebraska, with forecasters predicting up to 9 inches of snow. A foot has already fallen in the town of Rushville.
In Arkansas, meanwhile, storms have unleashed at least two tornadoes and have prompted flash flooding warnings.
There have been reports of damage from the twisters, but no one was hurt. Forecasters expect up to 7 inches of rain in central and southern parts of the state.

A powerful autumn snowstorm is slowly moving out of Colorado toward Nebraska and Kansas, causing blizzard-like conditions on the eastern plains and leaving in its wake treacherous roads and hundreds of canceled flights.
The storm dropped more than three feet of snow in areas of the foothills west of Denver and closed schools and businesses. Roads across the region remained snowpacked and icy.
At Denver International Airport, United Airlines canceled about half its flights to prevent delays and cancelations from spilling over into the next day. The National Weather Service said the area around the airport received between 11 and 16 inches of snow.
The Colorado Department of Transportation shut down Interstate 70 from near Denver to Burlington, which is about 15 miles from the Kansas border. Other road closures included a 40-mile stretch of Interstate 80 from Cheyenne to Laramie; and a 35-mile span of Interstate I-25 from Wellington to Cheyenne; and I-80 west of Big Springs to Laramie, Wyo., a stretch spanning almost 200 miles.
