I'm not saying it's right, I'm only saying -- this is what the 12z run of the NAM shows starting Saturday morning. Check out these maps and tell me if you've ever seen anything snowier.
Dawn on Saturday. Precip moves in with temps below freezing
Early Saturday afternoon. That's more than .75 liquid in a 6-hour period -- apparently all as snow. If accurate, that's 1-inch per hour snow for 6 hours. You do the math.
Saturday evening. Storm winding down, but not before another 2-3 inches falls.
Only thing about this run is temps look a little iffier, so we'll have to look at 12z GFS very closely. Still, the amazing thing about this event is that it is so CLOSE -- onset us just 48 hours away!
More to come......
