Along the leading edge of an advancing deep freeze, heavy snow caused major travel delays up and down the East Coast on Tuesday.
As the storm reached the coast, it began to strengthen and set the stage for heavy, wind-driven snow along a large part of the I-95 corridor in the Northeast.
Numerous daily snowfall records were broken on Tuesday as a result of this storm from Maryland to New York and up to 15 inches fell in parts of New Jersey.
In Philadelphia, 13.5 inches fell which broke the previous record for the date of 3.4 inches from 1917.
In New York City, 11 inches was measured at Central Park, breaking the record for the date of 6 inches from 2001.
Boston was spared the heaviest snow, but areas just to their south received a foot of snow.
On Tuesday, more than 7,000 flights had been delayed or canceled due to the winter storm across the U.S., according to FlightStats, with most of those in the Northeast.
Because every major hub in the Northeast was impacted by this storm, air travel problems will carry over into Wednesday. More than 1,500 flights were already canceled as of early on Wednesday morning according to FlightStats.

This storm will continue to move away from the Northeast on Wednesday and bring snow and wind to parts of the Maritime Provinces in Canada.
In the wake of the snow, the door will open for cold air to settle across the entire East. Highs on Wednesday will be held 10 to 20 degrees below normal, even in Miami.
Sunday morning was the coldest so far this winter across most of South Florida. Frost even made a rare appearance in Naples and the western suburbs of the Palm Beach metro area.
Wednesday night may not be quite as cold as this past Sunday morning, but frost could return to the coldest interior locations of the Florida Peninsula.
Another dose of cold air will follow later in the week for the South.
