PHILADELPHIA (CBS) — Roads will remain treacherous into the early morning hours. Some areas along the I-95 corridor will dig out from over a foot of snow.

As of 11 p.m., Philadelphia International Airport recorded 11 inches of snow. I expect the final total to be a foot or more! It is the biggest snow of the season, but we would have to beat 15.8″ to make it into the top ten snowstorms!

The low pressure system responsible for this mess is moving farther out to sea.

The snow has ended in PA and will end in New Jersey overnight. Temperatures will plummet into the single digits overnight.

To add insult to injury, along with blowing snow, we will wake up to vicious wind chills Wednesday.

A Wind Chill Advisory is in effect. Northwest winds gusting to 35 mph will make it feel more like 0 to minus 10 degrees at times.

Temperatures Wednesday afternoon won’t climb out of the teens and that will rival the ‘Polar Vortex’ temperatures we experienced just a couple weeks ago.

The cold air will remain in place through the end of the week with temperatures in the teens and twenties, so this snow will stick around for a while!

There is another chance for snow on Thursday as our next system approaches from the Great Lakes. The Eyewitness Weather team will keep a close eye on the snow and frigid air, but for now stay safe and warm.
