As much as a foot of snow was dumped on parts of southern Missouri on Sunday, closing part of an interstate highway. In southwest Missouri, troopers responded to at least 100 accidents in just over three hours, said Lt. Mike Mulholland.
"We're telling people if they don't have to travel, if they're in a warm spot, stay put," said Ken Tretter, spokesman for the Highway Patrol in St. Louis. "It's not a good night to be out."
In northern Oklahoma, between 10 and 20 inches of snow fell Sunday, causing a 75-vehicle pileup that injured as many as five people and stranded dozens for hours, authorities said.
A chain-reaction occurred when several cars driving into blizzard-like conditions on Interstate 44 collided, said Michelle Paul, a spokeswoman for the Oklahoma Transportation Authority.
Freezing temperatures that turned rain to snow helped ease flooding concerns in Ohio, but driving was treacherous. One death was blamed on the storm in Ohio.
The storm doled out snow, freezing rain, sleet, rain and thunderstorms in Maine — all topped off by high wind on Sunday night. An estimated 12,300 customers of Central Maine Power Co. lost electricity, said Kevin Hows, a company spokesman. By morning, however, reports CBS Radio affiliate WGAN, that number was reduced to just 2,000.
"It's been a multifaceted, multitalented storm," National Weather Service meteorologist Jim Hayes said. "A potpourri for meteorologists."
Up to 2 feet of snow in two days brought badly needed precipitation to much of Colorado, but also triggered dozens of avalanches Sunday.
A backcountry skier was caught in a slide near a ski resort, said Scott Toepfer of the Colorado Avalanche Information Center in Boulder.
The skier was swept over a 20-foot cliff and was buried. A ski tip was sticking out of the snow and a companion was able to rescue him.
In the Northeast, it wasn't snow that caused problems.
Ice was heavy enough to pull tree limbs down in upstate New York, meteorologists said. Several roofs collapsed, and one man was trapped for 20 minutes after he tried to clear a barn roof in Rensselaerville, 20 miles west of Albany.
In Maryland, residents continued to endure flooded basements, strong wind and icy roads after a weeklong state of emergency ended Sunday.
Several people were hospitalized Sunday after a multi-car crash on Interstate 70 near Indian Springs, Md., state police said. On Saturday, nine people were injured when the roof of a Toys 'R' Us store in Lanham, Md., collapsed due to heavy rain.
Minor flooding was reported throughout West Virginia as rivers and streams spilled after heavy rain and melting of last week's snow and ice.
In Virginia, two people died over the weekend — including a man who was rescued after his truck was swept away but tried to return to the vehicle.
And heavy fog shut down the entire length of the New Jersey Turnpike for several hours Sunday.
The Northeast could be in for another big storm, too, warns CBS News Meteorologist George Cullen.
"This extremely cold air for this time of year is going to be spreading east, and it's starting to look a lot like what we saw last week when we had our big snowstorm," he said. "There are similarities here, so if you live along the East Coast, you better watch out for Thursday, because we could be looking at another major snowstorm."
The snow in Oklahoma caught some residents by surprise.
"I haven't seen it this bad before," said Larry Kitchens, a dispatcher for Ponca City, Okla., fire and police. "I've been here since 1977, and this is pretty bad."
Temperatures will stay cold Monday.
"We have a lot of extremely cold air moving across the Great Plains today," said Cullen. "We're going to be looking at temperatures only in the single digits from Kansas to the Dakotas, and in some parts of the Dakotas, it will not get above zero."
