Unfortunately NWP experts are going to say their models are infallible and most of the times they aren't going to be using them to forecast day to day. We have seen better sampling make a huge difference especially in situations like this where you have so many moving parts. I mean we have monster storm in the northeast, the ridge behind it, how much confluence ends up behind it, 2 systems in Canada and the main system itself which doesn't want to figure out if it's coming out all at once or in pieces. I really feel for you guys in NWS on this one because there are like 5 different outcomes and all could be right. Hell there are even a few GEFS members that bring rain almost to here.
