I get what you are saying, but there are always multiple variables at play that factor in to the ultimate outcome. In this case it is more where the thermal boundary is located vs a more amped wave. The flow is relatively flat and west to east, and the vorticity is stretched out accordingly, underneath an upper level jet streak. Compare the vorticity on the 6z GFS and 6z Euro runs. No real dig in either case, and a subtle difference in the boundary location. For all practical purposes their outcomes are the same. In this situation the heavier snow(such that it will be) could be biased a bit NW or SE.
