2011 and 2016 stand out. Has it been much warmer?

I plotted them, and what stands out is 2011 (anomalously late) and 2015 (anomalously early). If you were to ignore those two data points, there would be a neatly linear trend of later snowfalls in the remaining four; but there's no reason to, except to artificially create such a trend.

If you don't ignore them, simple linear regression says there's no significant trend. It is only six data points in one location, though.

11, actually, but the older ones don't change the story much. http://bungo.livejournal.com/121052.html

It's much more impressive if you ignore 2011
