15/16 doesn't really count as that wasn't really a comeback but all of our annual snow from one storm in January. I remember 14/15 being pretty solidly wintry - that was the year Boston got just storm after storm right?
I don't recall many comebacks (at least when I lived there in the 2010s) given what the area has gotten so far. Don S will tell you the probabilities of reaching climo in NYC at this point.
