Theoretically speaking , you can also reach a point where despite larger storms the underlying modifying temps and less frequency of cold systems overcomes the former and the “line” that determines where snow is increasing may be moving streadily NW and or toward elevation (In New England ) and beyond , also at the same time another “line “delineating” falling annual snowfall (to the SE of the first line) is also marching NW and creeping into NYC and burbs , Cape and Coastal SNE and then beyond due to the milder temps outweighing the juicer systems when it comes to net/net annual snowfall changes
I’m not saying it is as I have no idea and Data wouldn’t conclusively show this till way past it started (to confirm it wasn’t a blip decade or two) especially with all the inherent variability in SNE but it’s just the way I think it could play out over time . NNE would also probably begin to see greater variation then they are used to if that process were unfolding
