I don’t disagree but when you’re looking at 100 year trends you also have to take into consideration the differences in urban areas along that 100 year journey. Lot more concrete and asphalt now vs then. The March 2013 storm is a great example. Just a few miles outside of that heat island was heavy snow. A degree or two made all the difference.
I think to draw conclusions on the 100 year trend with snowfall you’d have to get away from urban locations and look at a small regional collection of data. I know that I’ve looked at the data for Winchester and the thing that stands out the most is the randomness of the high and low snowfall totals.
I definitely think the climate will be a factor, just not sure that’s necessarily gonna show up in snow totals, or what that factor will be. Now if we get 10 of the next 15 winters as warm as last year, I might be singing a different tune.
