In January 1996 I was 20 years old and and home from college for winter break at my house in Central NJ (Monmouth County). The Blizzard of 1996 was the most snow I have ever seen from a single storm. We got about 30" from that storm.
I moved to the DC area the next year. The most snow I received from a single storm since I've been in this area was in 2016 when I got about 26".
The most snow I ever had on the ground at one time, however, was after the 2/10/10 storm. We had gotten about 24" from the 2/6 storm and then another 12" on 2/10 (along with wind and blowing snow).
I voted for '96 simply because it was the most snow I had ever seen from a single storm. If the February 2010 storms were combined into a single entry I would have voted for that.
