CONCORD, N.H. (AP) — A powerful winter storm was expected to drop one to two feet of snow on parts of the Northeast just a day after it swept through the nation's middle, dumping a record snowfall in Arkansas and ruining holiday travel plans for thousands.

The storm, which was blamed for six deaths, pushed through the Upper Ohio Valley and made its way into the Northeast Wednesday night. Within hours, there was anywhere from a few inches of snow to a dozen in some locations.

National Weather Service spokesman David Roth said the Northeast's heaviest snowfall would be in northern Pennsylvania, upstate New York and inland sections of several New England states before the storm ended Friday morning and headed to Canada.

Little or no accumulation was expected in the East Coast's largest cities: New York, Philadelphia and Boston. Other areas were to get a messy mix of rain and snow or just rain — enough to slow down commuters and those still heading home from visits with family.

Hundreds of flights were canceled or delayed on Wednesday and scores of motorists got stuck on icy roads or slid into drifts. Said John Kwiatkowski, an Indianapolis-based meteorologist with the weather service: "The way I've been describing it is as a low-end blizzard, but that's sort of like saying a small Tyrannosaurus rex."

The storm system spawned Gulf Coast region tornadoes on Christmas Day, startling people like Bob and Sherry Sims of Mobile, Alabama, who'd just finished dinner.

"We heard that very distinct sound, like a freight train," said Bob Sims. They headed for a center bathroom.

Power was still out at the Sims' home on Wednesday, but the house wasn't damaged and they used a generator to run heaters to stay warm. Some neighbors were less fortunate, their roofs peeled away and porches smashed by falling trees.

The storm also left freezing temperatures in its aftermath, and forecasters said parts of the Southeast from Virginia to Florida saw severe thunderstorms.

Schools on break and workers taking holiday vacations meant that many people could avoid messy commutes, but those who had to travel were urged to avoid it. Snow was blamed for scores of vehicle accidents as far east as Maryland, and about two dozen counties in Indiana and Ohio issued snow emergency travel alerts, urging people to go out on the roads only if necessary.

About 40 vehicles got bogged down trying to make it up a slick hill in central Indiana, and four state snowplows slid off roads as snow fell at the rate of 3 inches an hour in some places.

Two passengers in a car on a sleet-slickened Arkansas highway were killed Wednesday in a head-on collision, and two people, including a 76-year-old Milwaukee woman, were killed Tuesday on Oklahoma highways. Deaths from wind-toppled trees were reported in Texas and Louisiana.

Larry McClain and John Crider, each driving a mobile construction crane from Shady Grove, Pa., traveled only 15 miles before snow forced them off the highway and into a McDonald's in Hagerstown, Md. The vehicles aren't permitted to travel in snow.

They planned to spend the night in a motel before resuming their trip. Crider was headed for Oklahoma City and McClain for Corpus Christi, Texas.

"We were hoping they would have told us to stay at home today but they thought maybe we could get south and beat the storm — but we didn't do it," McClain said.

The day after Christmas wasn't expected to be particularly busy for AAA, but its Cincinnati-area branch had its busiest Wednesday of the year. By mid-afternoon, nearly 400 members had been helped with tows, jump starts and other aid, with calls still coming in, spokesman Mike Mills said.

More than 1,600 flights were canceled, according to the aviation tracking website FlightAware.com, and some airlines said they would waive change fees. By early Thursday only minor delays were reported.

In Arkansas, some of the nearly 200,000 people who lost power could be without it for as long as a week because of snapped poles and wires after ice and 10 inches of snow coated power lines, said the state's largest utility, Entergy Arkansas. Continued...
