The heavy snow falling along much of the mid-Atlantic Coast into New England is expected to taper off Friday as a nor'easter heads into Canada, leaving bitter cold in its wake, the National Weather Service said.
By early morning, the snowfall was nearly finished in the nation's capital; it was expected to stop by late morning in New York City, where 6 inches were covering Central Park, and by early afternoon in Boston, which got socked by nearly 15 inches.
North of Boston, residents of Topsfield, Massachusetts, got nearly 2 feet of snow.
The combination of cold and winds gusting more than 30 mph was expected to lower wind chill temperatures to less than 10 degrees over the mid-Atlantic and into the teens in New England.
Correspondent Laurie Segall was in Chatham, Massachusetts and shared a picture of her live truck stuck frozen in the snow.
But not just the Northeast will be hit, forecasters said. About one-third of the nation - approximately 100 million people in 22 states - is in the path of this storm.
Snow was also predicted from the Upper Midwest into the Great Lakes, with as much as 8 inches expected in Michigan's Upper Peninsula and additional snow possible along a cold front that extends through the Midwest and into the Central Plains, the service said.
Across the country, the weather has snarled travel plans for many.
FlightAware.com, which tracks cancellations due to weather and mechanical problems, said more than 1,800 flights had been canceled for Friday. That's after more than 2,600 U.S. flights were canceled Thursday.
Flights were expected to resume later Friday in much of New England, though delays were predicted in some airports. Ticket holders were urged to check with their airlines.
Barb Plooster had planned to fly Friday from Erie, Pennsylvania, to Grand Rapids, Michigan, but her flight was canceled. She told CNN affiliate WICU that she was on the phone with United Airlines for five hours trying to find a way to get home, but has concluded that she will have to wait until Monday. "We got a warm place to stay, get to visit the kids, the grandkids, so it's OK," she said.
