A potentially major snowstorm was expected to hit the Philadelphia region from Monday night through Tuesday. Preparations were in high gear Monday night and the impact of the severe weather was already being felt at airports. Here's what you need to know in advance of the upcoming snow.
Forecasters are warning of a "nasty" nor'easter, with periods of dangerously high snowfall rates and whipping winds. The storm was expected to move in late Monday and could continue through Tuesday night, when the precipitation should taper off. The National Weather Service says to expect eight to 12 inches of snow in Philadelphia, with higher amounts in the Pennsylvania suburbs and lower amounts in South Jersey.
The final National Weather Service map published Monday projected 12 inches of snow in the city.
A winter storm warning for the area was put in place from 8 p.m. Monday through 6 p.m. Tuesday.
Along the Jersey Shore, Ocean, Monmouth, and Middlesex Counties were under a blizzard warning due to the whiteout conditions expected there.
In the Philly suburbs, Montgomery, Chester, and Bucks Counties were also under a blizzard warning.
The heaviest snow and strongest winds are expected overnight and into the day Tuesday, setting the stage for a particularly hazardous Tuesday morning commute.
The weather service warned that people in places northwest of I-95 "should be thinking about sheltering in place" from 2 a.m. to 2 p.m. Tuesday. In parts of eastern Pennsylvania and North Jersey, snow could fall at a rate of two to four inches per hour.
Some rain and sleet could mix in with the snow at times, and throughout Monday forecasters cautioned that there was a range of potential snow totals. Early weather service maps on Monday forecast seven inches as likely in Philadelphia, with the potential for more than 20.
This storm is also expected to be a windy one, with northeast winds of 15 to 25 mph and gusts of 35 mph near Philadelphia and over 50 mph closer to the coast.
The late-season storm is forecast to slam the bulk of the mid-Atlantic and Northeast.
Tuesday's high temperature was expected to be in the low 30s, with similar highs forecast for Wednesday and Thursday. So the snow is unlikely to melt quickly.
Philadelphia public and parochial schools will be closed Tuesday.
Temple University said it would be closed for the day.
PennDot is advising drivers to stay off the roads during the storm, but as of Monday afternoon no highway closures were planned, officials said.

New Jersey's Department of Transportation had not issued any restrictions or closures as of Monday afternoon.
