It connects most the dots in the best way though. If you dont use CC then there are two different sets of changes you have to explain. Besides the higher snowfall totals along the coast right now, the other one is DC's decaying snowfall climatology. Back in the 80s and prior, Dulles used to outdo NYC in about half their winters in snowfall. Now it rarely ever happens anymore. So what we're seeing is decaying snowfall averages to our south. If you follow the conjecture that I was using the other day, you can explain it by saying that our coastal plain is in an intermediate stage right now, where higher RH has yielded bigger events but eventually it'll all catch up and our coastal regions will be the first to experience the decaying DC snowfall climatology; that line is slowly moving north.
First we are seeing the higher RH benefits of being further east but eventually the warming will catch up to us from the south- I give it until 2050 for that to happen and then our snowfall climatology will resemble where DC has decayed to now. It also bolsters my conjecture that the storms that were going out to sea back then are now coming closer to the coast, because a stronger SE Ridge would not only move the storm track further to the west, but also further north. Based on that, the storms that are hitting the area right now would have fringed us back then (and perhaps hit the DC area directly before passing well to the south and east of us.)
