Those ENS snow maps at that range are pretty useless imho. Swing pretty wildly, prone to being weighted towards a few really bad or really big hits etc. Years past these maps did show more, but it's not like they ever verified then either. They did correct some bad bias'es that made them lean more snowy, so that's at least part of it. Only thing you can really glean is that at least as of that run, the pattern *may* be conducive for above average snow for the month of January.
If its bad I wouldn't lose sleep over it, and if it looked great I wouldn't be teeing up the "It's Happening" Gif either...
