As I've noted in the past, I learned of this dictum from a Rutgers met; this is true for most of NJ anyway. We had the same discussions in the early 90s about the lack of snow, at which time it had not snowed significantly in some 5 years. 92 would feature two smallish storms in March, then a decent Feb 93 event followed by March ( non ) Superstorm in NYC ( 10 icy inches ) before 94 would set a new bar, to be broken two years later in 96. After which we went another 5 years with the snowblower in mothballs.....we can very easily see little snow for half a decade, I've seen it a few times in my life.
