The heaviest snow pushed off to the east Friday morning after leaving more than 10 inches of snow on parts of the area and at least 5 inches in many neighborhoods.
Heavy snow fell overnight into Friday morning as the first winter storm of 2014 moved through the region -- prompting widespread school closings, a state of emergency and many travel delays.
It also caused fender benders, stuck cars and two jackknifed tractor-trailers on major roads including I-95 in Pennsylvania and the New Jersey Turnpike.
Two storm systems, one from the north and west and another from the southeast collided to envelop the area in snow, ice and strong winds as temperatures tumbled to frigid levels. A Winter Storm Warning is in effect for the entire Philadelphia region from the Poconos to the I-95 Corridor to South Jersey to Delaware.
The winter storm prompted hundreds of schools and school districts to close on Friday -- including the School District of Philadelphia and all city Archdiocesan schools. Many local and county governments also issued snow emergencies. Concerned with public safety in the Garden State, New Jersey Gov. Chris Christie declared a statewide snow emergency on Thursday afternoon.
"The impending weather conditions over the next several days will produce a variety of dangerous travel conditions throughout the state," Christie said. "I encourage all New Jerseyans to stay off the roads if possible so that our first responders and public safety officials can safely respond to any emergency situations."
Speed limits were lowered to 45 mph on most major Pennsylvania roads including the Pennsylvania Turnpike (I-76), the Northeast Extension (I-476), US-202, US-422, the Roosevelt Boulevard (US-1) and the Vine Street Expressway (I-676) and to 25 mph on area bridges as conditions deteriorated.
Amtrak changed its Friday schedule, reducing the frequency of trips along the Northeast Corridor, anticipating weather-related problems. SEPTA suspended some bus lines and had a number of delays on its bus and rail lines as the storm intensified. Officials recommend checking the transit authority's system status website for the latest information.
At Philadelphia International Airport, 160 flights were canceled on Thursday. Airport officials tell NBC10 they expect more trouble on Friday thanks to the high winds that will be sticking around after the snow stops falling. Travelers can check the latest flight status by calling 800-PHL-GATE or by visiting PHL.org.
