This happens quite often when it drifts south. I think it has to do with the topography of the coast along with the southern portions hitting the boston hills. This was not modeled well.
I would count last year as high magnitude. They get quite a few events but it's tough to get a major storm there. A consistent SSW wind setup is extremely difficult for LES.
You'll definitely get hit later, but the band will not be as intense as it was near Buffalo. It's also moving quickly and shear will impact it later today.
