I don't think we've discussed much the elongated, lobed depiction of the surface low along the coastal front much. It's been shown this way in various solutions. The 12z RGEM takes this to the extreme, with meso lows chasing convection east of the benchmark, competing for supremacy with the sfc low trying to establish east of the VA capes with where there's better UL support for sfc low development. The result is the forcing is strung out and discombobulated and steadier snows do not advance into NNJ or SNY. I don't see why this isn't just as plausible as anything else.
