Yeah that sounds about right. In my head I sort of lump you guys in with up to Dryslot's area, as I bet Dryslot has more in common with ORH snowfall than he does with Vermont at the same latitude. The snowfall climatology in the northeast seems to run in SW to NE axis, mirroring the coastline. Like up here we often share storms that deliver NW of ALB, more than we do with say far N.NY or Massena despite the similar latitude. I know you know this, ha, just speaking out loud.
The main point though is what you made, if one region really does well, the other normally does pretty good too. Relative to normal as a percentage, I still think SNE often gets the nod in those "good/great" winters. Like 120% snowfall up here is a huge winter and I bet when that happens, it's not uncommon for BOS/BDL/ORH to have at least 120% of normal, maybe more. That's probably a pretty poor metric though to compare, as standard deviations would be more useful. Maybe that's where I'm stuck at, looking at it as a percentage of normal snowfall... it's hard to beat the non-immediate coastal SNE stations in that metric during a good winter.
