A nor’easter will bring some accumulating snowfall to the I-95 Corridor and points north and west overnight and winds and rain to the Jersey Shore.
The National Weather Service issued a Winter Weather Advisory for the entire Philadelphia region ahead of the storm, which moved in late Friday night and will move out Saturday.
The storm will bring snow, sleet, possibly freezing rain and rain to the region with areas north and west of the I-95 Corridor getting mostly snow and areas south and east getting mostly rain, said Henley..
"Most of this is going to happen while people are sleeping," said Henley. "They'll wake up to a slushy mess."

The storm began Friday night with rain in southern locations.
Conditions will intensify overnight leaving heavy, wet snow on much of the region. Henley said the changeover could occur before sunrise.
"Sleet and freezing rain will come in around the same time," said Henley.
A wintry mix will give way to rain for much of the area Saturday eventually tapering off -- with more possible snow -- in the late afternoon or evening but not before leaving heavy, wet snow on the ground for most people in the region.
Estimate Snow Totals:
Philadelphia & immediate suburbs - 1 to 3 inches (snow, sleet & rain)
Western and northern suburbs - 2 to 4 inches (snow, sleet & rain)
Lehigh valley, higher-elevated suburbs - 3 to 5 inches (mostly snow -- some mixing)
Poconos - 3 to 6 inches (snow)
Central & southern Delaware & New Jersey - Mostly rain & gusty winds
You probably want to shovel out Saturday night because what’s left on the ground could re-freeze as temps dip again heading into Sunday, Henley said.
By Saturday afternoon, temperatures will move into the mid-30s.
Sunday will be mostly sunny with a high around 40 before another system, an Alberta clipper, moves in overnight into Monday bringing more snow to much of the area.
