Idk, seems like they're living in the past. Especially when you consider what Lwx is thinking. In any event, I think this is a 2-4" or 3-6" event imby from what I've seen so far.
It has that tongue of higher snowfall a bit north of other guidance that's showing the same feature. I'm on the south end at 3". Won't be surprised with a future adjustment if other guidance holds onto it.
