In addition, it's difficult to get big snowfall in this region without some type of storm system. There was nothing at the surface. The system at the 500 MB level was not impressive and the 700MB winds were from the SW. There was more of a system at the 850 MB level to help with lift at that level. So the entire system was based on the 700 MB and 850 MB response. There was always going to be more QPF squeezed out in the persistent bands of snow and where they set up which tied in with where the various fronts were. With that being said, the GFS/NAM are almost always too moist and generate too much QPF.
