Correlations Between First Day of Snowfall and Seasonal Snow Totals

When comparing the average first dates of snowfall to the years actual snowfall accumulation, one does not find a very consistent trend appearing. What is interesting to note however, is that when the date of first snowfall is anomalously early, we typically see an increase from the average snowfall totals for the year. Conversely when the dates are anomalously late in the year, the yearly snowfall is seen to be slightly less than average (in most cases). The interesting fact however lies in that, over the past 32 years, our first day of snow has been starting progressively later in the year for all regions of the state. Below are individual cities along with data on yearly snowfall, date of departure, and a comparison of first snow day departure dates with ascending years.
