I would agree about the luck aspect of it except that 2015-16 followed the 1982-83 script to a tee, it just happened a few weeks earlier. In el ninos that strong a one hit wonder megablizzard might be all one should expect. Also note that in all high end strong to super el ninos, the highest snowfall amounts in those snowstorms are usually around the south shore of Long Island into JFK, thus was the case in 1982-83, 2003 (PD2), and 2015-16.
And we had some near misses and 2 moderate hits in February too, if you'll remember, there was a snowstorm in February that caused a crane to fall in NYC and we had another moderate hit around the superbowl, something like 4-6 inches I think for each of those storms? JFK ended up with over 40 inches of snow and parts of Long Island were at around 50 inches of snow.
Basically the eastern parts of the city were the western extent of the 4-6 inches in those February storms.
