The interesting thing is how the NAM does not bring this solution to light. It appears that the models are divided into two camps:
Snowstorm Camp: GFS, ECMWF, JMA, UKMET
No Snowstorm Camp: NAM
(GEM has mostly rain but back-end snow, will not put in category)
I would say that there ought to be a snowstorm, but may not be as severe as some models are projecting.
