Yes agree rain is not even really a possibility in this setup with a high like that. If the low somehow hugged the coast worst case scenario is sleet but most likely its either heavy snow, light snow on the fringe, or nothing.
I'm leaning suppression less because of what the OP models are showing this far out and more just the pattern/strength of high/depth of cold. I can't think of the last time NYC saw a significant snowstorm at 10 degrees, we don't have 90s climo anymore. Could it happen? sure I guess.
It's also possible the models could be overdoing the high/cold etc.
Honestly i'd be fine with 2-3 tonight on top of what we have. A bigger storm would be nice but with a cold week ahead a grassy snowpack of 5 inches or so is nice.
Yea it depends on the rates, the correct thing is generally if it's 32 or warmer with light precip you won't get good accumulation in the five boroughs (especially the more densely populated parts). Heavy snow will stick anywhere except maybe midtown.
if a band forms somewhere from northern NJ/LHV/into interior CT could pick up 6 inches tomorrow on top of what fell today. The models often miss a band on the NW edge of the main snow.
