Weekend snowstorm update

There seems to be a lack of model consensus between the NAM, GFS, ECMWF(European), CMC, GEFS, and DGEX regarding the storms track. The models have been trending west due to the slight movement of the polar vortex in Canada. The precip shield has expanded ever so slightly if this continues, 1-3″ of snow or more can be expected over this weekend. Does not seem like a very slow moving storm. Lacking a really good block.
