Yeah snowfall retention and days of pond ice probably are decreasing over a long term (The 70s were a very cold decade though). I bet off the top of my head those warmer years in the 30s and 40s probably had lower pond ice days and retention...but agree the long term trend is there. To Ray's point, we haven't seen the scale tip (and won't for awhile) to where snowfall starts being significantly impacted by GW. Maybe the more marginal ones are uglier....but in the grand scheme of things...most of New England outside of the coast typically has a cold antecedent airmass prior to snowfall that is well below 32F.
