It was a really well modeled storm. The big models had it for nearly a week. They had it locked in for several days. It did trend west a bit but more so with the precip field and ULL features that moved E-W. Big shout out to the LR NAM for being the first to see it.
Mixing was well modeled and just about inline (as opposed to often worse).
That Syracuse effect was really bizarre. It has to be that raging eastern jet hitting the mountains and then falling in elevation over that area. It was absurd.
