A nor'easter that brought rain, high winds and flooding to parts of the Philadelphia region could still bring snow to other areas overnight into Wednesday.
"It’s a long lasting event because the storm itself is stalled,” said NBC10 First Alert Weather chief meteorologist Glenn "Hurricane" Schwartz.
Snow could fall in Philadelphia and along the I-95 corridor Wednesday but it should fall in the Poconos and more than likely will fall in the Lehigh Valley and Berks County, said Glenn.
The National Weather Service issued a Winter Storm Advisory 6 a.m. Wednesday for Monroe and Carbon Counties in the Poconos with 1 to 3 inches of snow possible.
Snow should begin overnight in the Poconos and could start before daybreak north and west of the city and in the Lehigh Valley. Snow could fall later in the day closer to Philly.
Bands of snow rarely seen during nor’easters make this storm hard to read.
"What we’re going to be looking for are bands of heavier snow,” said Glenn. "Sometimes in setups like this they can develop and then stay over the same areas.”
Flooding was a concern earlier throughout much of the region.
A wintry mix of freezing rain, sleet and snow began falling in parts of the Lehigh Valley and areas north and west of Philadelphia Monday into Tuesday, while the Philadelphia area experienced downpours early Tuesday morning. The heaviest rainfall began to move past the Delaware Valley during the morning rush hour, but lighter precipitation and strong winds persisted throughout Tuesday.
Coastal flooding caused roads to flood in Atlantic, Cape May and Ocean counties.
Glenn expects the storm to affect the area beyond Wednesday.
"There’s still a chance of snow flurries or snow showers on Thursday,” said Glenn. “The storm is going to pretty much stall over New England and that’s going to keep it windy and cold here for the rest of the week and every once in a while a little snow could spin all the way around that storm and come down.”
