All of us should see some snow and rain showers at some point over the weekend, so be prepared with everything from umbrellas to snow shovels. Also leave extra drive time with slippery roads across the region.

2-4″ of snow possible for Philly and either side of the I-95 corridor.

A coastal low will pass close enough for another round of snow and rain mainly I-95 and areas south and east. Light early morning snow is possible north and west of the city with rain for I-95 and South Jersey. By late morning, the rain will change to snow over South Jersey and I-95.

As the coastal low moves away from our area in the afternoon any snow will shift to South Jersey. Two inches of snow is possible for inland South Jersey and the Shore.

Less snow in the northwest, a little more northeast—toward Trenton, we could see a few bands setting up to get up to 5″ in a few spots.
