Yes. While we were getting shellacked, the Canadian came in with 5" - 10" at 12z and we all laughed. Then the Euro came in with 15" - 20" and suddenly we knew something special was happening. There was a last minute bump north, but that was mostly because the block was decaying and it allowed for more poleward movement at 500 mb.
We do not appear to have such a scenario this time around. It's a healthy block.
Early on, but to me the big thing seems to be how this ridge out west is handled, too far east and this thing swings out to sea. This is not a comment on a specific model, just an overall observation.
For the next day or two I would lean more weight towards the ensembles, both AI and traditional. If we start seeing a better clustering for the coastal low, and perhaps it climbing the seaboard more, then it's likely game on.
06z Euro AI-EPS has a mean 850 temp during the storm of -10 to -15. Very supportive of good snow growth. It also would lay a good boundary for the 850 low to track to our south.
The west coast 500 mb ridge on the EPS is textbook for a major east coast snowfall, and has trended in a more favorable direction over the past several runs.
