I have been tracking Central Parks snowfall total starting with the 2018-2019 season and comparing it to the 30-year Central Park snowfall drought average from 1970 through 1999 which was a little over 21 inches. Central Park is currently a little over 15 inches for this period, however, the 1970s had very low snowfall for Central Park outside of 2 years towards the end of the decade. This snowfall drought for Central Park can last a lot longer, however I agree by the early 2030s if we're seeing the same thing over and over again then we have to consider.
In that 30-year time span Central Park had only five above average snowfall seasons, and 14 of them were below 19 inches. Central Park already had one above average snowfall season in this period so on track in that regard. If we get another 1978 type snowfall distribution then the average will be comparable.
