But average increase of annual snowfall totals vs more frequency of big precip snow "bombs" are two different things. As you know, one big event can make up for an entire season's snowfall (a great example of this was the January 2016 big snow that dumped over 30" here.)
The average annual rainfall went from around 40" during the 70s/80s to around 50" now, which is a pretty significant increase.
The increase in snowfall should be transitional anyway, in a warming climate, we'll eventually get past this stage. The increasing precip totals, higher humidity levels and higher temps will have much more long term impacts though, including more tropical diseases spreading into our area (we've already been seeing that over the past decade.)
