    Just about ready to call this one. Let’s see what 0z does. Could the Canadian capture a HUGE coup

    Probably not, but... the GEM/RGEM were the closest to nailing the snowfall axis with the last storm amongst atleast the global models for the upstate area. The GFS and esp the Euro were too far SE by 30-40 miles. But that was also a much more minor variance vs. what will be needed to score on this storm as it stands right now.

    Looks like it gets progressively worse from West to East across NYS.  BGM might be a slight anomaly due to the airport's high elevation relative to other cities, as well as to downtown Binghamton.  Isn't the airport something like 1600'+ while downtown is around 800-900'?  That would sort of be like Albany's official weather records being recorded on the Helderberg Escarpment (Thatcher Park, around 1000') instead of where the airport currently is at around 300'.

    Lol... yeah that's correct. Though I think it's all relative to some extent. I think the downtown area averages about 65-70 while the airport averages 85. The differences on an individual storm level really manifest themselves in the early and late season storms that are much more elevation dependent and there really hasn't been much of that this year with the late start to winter. But I can definitely recall numerous storms in the month of April where the airport got pasted with 12" while us valley folks only got a coating to a few sloppy inches. But I'm also about 930' and only 4 miles west of the airport and I've been nearly right on par with the official airport/nws snowfall reports each storm thus far this winter. Myself and the airport are both on a nice nw flow trajectory for some occasional LES goodies off Cayuga Lake that the city proper to the south usually misses out on, and that also helps a bit over the course of the winter. 

    I'm also thinking the 700ft elevation difference between the 300' Albany proper and nearby 1000' hills you describe might not actually be the same pound for pound difference as the 900' valleys and 1630' airport here. Elevation difference will become more neutralized as you gain altitude... I.e. 900' / 1600' is 56% while 300' / '1000 is 30%. I think the orientation of the HRV also lends itself to more severe shadowing/downsloping effects on occasion that we don't really ever experience here. Once in while the Poconos and/or Catskills can cause some shadowing of southern/eastern Broome county including City of Bing proper but that tends to fade as you move further nw toward my area and the airport.
