A winter storm packing snow and Arctic cold slammed the northeastern United States on Tuesday, grounding 3,000 flights, shutting down governments and schools and making travel a potential nightmare for millions.
States across the northeast declared emergencies and warned residents not to travel during the fast-moving storm, which packed a potentially lethal combination of snow and wind, backed by temperatures up to 30 degrees Fahrenheit (17 degrees Celsius) below normal.
The system could dump as much as a foot of snow on southern New England and to snarl the evening commutes of millions along the I-95 highway corridor from Boston to Washington, said Bruce Sullivan, a senior meteorologist at the National Weather Service.

About 3,000 airline flights in the United States were canceled, according to FlightAware.com, a tracking service. The bad weather left thousands of air travelers wondering when they were going to get home.

"I actually had a class at 6, but I'm going to be late, I guess," he said.
Hours after he was sworn in to a second term, New Jersey Governor Chris Christie declared a state of emergency, as did Delaware Governor Jack Markell. Christie's inauguration party on Ellis Island in New York Harbor was canceled because of the looming storm.
In Massachusetts, Governor Deval Patrick postponed his annual state of the state address because of the weather.
