The huge storm stretched from Kentucky to New England but hit hardest along the heavily populated Interstate 95 corridor between Philadelphia and Boston. Snow began falling midmorning Tuesday in Philadelphia and had dumped as much as 13.5 inches by midnight, with New York seeing almost as much. Manalapan, N.J., had the highest snowfall reading with 16 inches.
The storm, which dropped nearly a foot of snow in parts of Massachusetts, promised to create headaches for motorists in Boston on Wednesday morning. Commuters in Philadelphia and New York had packed early trains or spent hours inching along roads in swirling darkness to get home the night before.
The New Yorkers and Bostonians who normally swarm Cape Cod in fishing hats or bikinis in July and August wouldn't recognize it this week. A blizzard warning through Wednesday afternoon kept business brisk at Aubuchon Hardware in Sandwich, where salt and snow shovels were popular.
"The flow of customers is pretty steady, but everyone waits until the worst of the storm to start worrying," manager Jeff Butland said.
Boston and Philadelphia ordered schools closed Wednesday, following the lead the day before of many districts in Pennsylvania, New Jersey, Connecticut, Virginia, West Virginia and Kentucky. Federal workers in Washington also got a snow day Tuesday.
Nearly 3,000 commercial flights were canceled Tuesday into and out of some of the nation's busiest airports, including in Washington, Baltimore, Philadelphia, New York and Boston, where Logan Airport advised passengers to expect extremely limited domestic service at least through Wednesday morning.
At New York's LaGuardia Airport, congested even on a good day, a television monitor displayed a litany of canceled flights. Crowds of people who had been hoping to fly out instead gathered around ticket counters trying to make alternate arrangements.
"We don't expect to get out here till 6 p.m. maybe, tomorrow," Paula Black said Tuesday after her flight to Chicago was canceled.
Amtrak told passengers on its busiest line, the Northeast Corridor between Washington and Boston, to expect fewer trains. Lines serving Harrisburg, Pa., and Albany, N.Y., also were slowed.
The storm put a damper on New Jersey Gov. Chris Christie's inauguration, forcing the cancellation of a Tuesday evening gala on Ellis Island. In Massachusetts, Gov. Deval Patrick postponed his annual State of the State address, saying he was worried about guests trying to get to the Statehouse.
On I-95, one of the nation's busiest highways, traffic was bumper to bumper Tuesday evening north of New York City, where some people simply gave up and tried to navigate side streets, creating another traffic jam in suburban New Rochelle.
"I just want to get to the Bronx," Peter Neuwens said. "It's a big place. Why can't I get there?"
The storm was a conventional one that developed off the coast and moved its way up the Eastern Seaboard, pulling in cold air from the Arctic. Unlike the epic freeze of two weeks ago, it was not caused by a kink in the polar vortex, the winds that circulate around the North Pole.
Nonetheless, overnight temperatures in the single digits were expected in Philadelphia and New York, with wind chills dipping into the negative teens. The frigid air extended to Kentucky, which was forecast to see similar temperatures and subzero wind chills.
The newest wave of cold air helped to deplete fuel supplies and send prices for propane and natural gas to record highs. Higher natural gas prices also are leading to sharply higher wholesale electricity prices as power utilities snap up gas at almost any price to run power plants to meet higher-than-normal winter demand.
Propane users will get pinched the most. Those who find themselves suddenly needing to fill their tanks could be paying $100 to $200 more per fill-up than a month ago. Homeowners who use natural gas and electricity will see higher heating bills because they'll use more fuel. But prices won't rise dramatically because utilities buy only a small portion of the fuel at the elevated prices.
The storm was blamed for at least one death in Maryland, after a car fishtailed into the path of a tractor-trailer on a snow-covered road about 50 miles northwest of Baltimore and the car's driver was ejected. Police said the storm might have claimed more lives: A preliminary investigation showed wet conditions played a role in a two-vehicle crash that killed two people in Prince George's County, Md.
