Storm next week followed by extreme cold?

For next week (Tuesday into Wednesday), the GFS (American model) has a storm moving through that really isn't packed with moisture. It's more of a clipper than anything which brings us rain/snow. However, the Euro (European model) has a different take on this. It has a much bigger system with much more moisture attached to it. This would mainly be in the form of snow (as of now). The GEM (Canadian Model) has a snow to rain to snow event. Again, more moisture than the GFS. So since two models are leaning towards a larger system, I felt it's worth talking about. The GEM says about 1-3" of snow to start, followed by about 0.2-0.3" of plain rain, followed by 3-6" of snow on the backside of the storm. The EURO says it will start as snow, potentially mix with rain and finish as snow. Snow totals would range from 7-10" across the area. The GFS says very little moisture. I'm talking not even a tenth of an inch of liquid. Some rain showers and snow...
