A winter storm that is projected to bring up to three inches of snow to Philadelphia is expected to spare the evening rush hour, but could affect Wednesday morning's commute.
Some snow has fallen around the area, including flurries in Center City, but it has been light and is fleeting.
Heavier snow is expected later in the day, arriving around 7 p.m. in western Chester County and upper Montgomery and Bucks counties, where a winter weather advisory is in effect.
The National Weather Service says the snowfall is likely to begin in Philadelphia around 10 p.m. and after midnight in South Jersey.
Accumulation projections range from 3-4 inches in Reading, to 2-3 inches in Philadelphia and 1-2 inches in Atlantic City.
The high Tuesday is expected to be 39 in Philadelphia with a slight chance of rain after 3 p.m.
Meanwhile, the weather service has continued a flood warning for the Delaware River at Trenton because of an ice jam.
"Minor flooding is expected along the river in Trenton, Yardley, Morrisville and Ewing Township," the NWS said.
