Philadelphia received 6.8" of Snow. This was one of the earliest Snowfalls of 4" or more recorded at that time. It Snowed all the way to the Coastline of NJ as well, with Atlantic City coming in with 6.7" of the White stuff.
Since I do not have the option to post images on here (not sure why it will not allow me), I am forced to link the information...Here you go!
