PHILADELPHIA -- A powerful storm that crept across the country dropped snow, freezing rain and sleet on the Mid-Atlantic region and headed northeast Sunday, turning NFL playing fields in Pennsylvania into winter wonderlands, dumping a foot of snow in Delaware and threatening a messy Monday commute in the northeast corridor.
The storm forced the cancellation of thousands of flights across the U.S. and slowed traffic on roads, leading to a number of accidents, including a fatal crash on the Pennsylvania Turnpike near Morgantown that led to a series of fender-benders involving 50 cars that stranded some motorists for up to seven hours. More than two dozen vehicles were involved in another series of crashes on nearby Interstate 78.
What was forecast in the Philadelphia area to be a tame storm system with about an inch of snow gradually changing over to rain mushroomed into a full-blown snowstorm that snarled mid-afternoon traffic along Interstate 95 in Pennsylvania from the Delaware to New Jersey state lines.
Paul Jones, 24, a youth hockey coach from Warminster in the Philadelphia suburbs, was on his way to a game in Lancaster when he got stuck - along with his fiancee, another coach and three players - in a major backup on the turnpike.
The roadway was "snow-covered, slick," Jones said in an interview from the car, where he was a passenger and had been at a standstill for more than an hour.
"People are in and out" of their vehicles, he said. "Kids are having a snowball fight on the side of the road, making snow angels, people are walking their dogs."
The National Weather Service said the low pressure system from North Carolina north to New England was being fed by disturbances from the southwest and moist air off the Atlantic.
A foot of snow was reported in Newark, Del. Philadelphia International Airport received 8.6 inches Sunday, more than it had all of last year. Other areas received far less: a little over an inch was reported in Pennsylvania's Lehigh Valley, which usually is hit harder than downtown Philadelphia.
The forecast for early Monday remained up in the air for the northeast, depending on how quickly the system moves and temperatures rise, according to the National Weather Service.
The expectation was for another weather system moving out of Virginia to follow the same path as Sunday's storm overnight. It was expected to dump icy drizzle and eventually freezing rain from Philadelphia northward through the New York City area and into Boston, National Weather Service meteorologist Greg Heavener said.
"The commute for people in the Philadelphia area and north, to northern New Jersey and New York will likely be disrupted by freezing rain," Heavener said.
