It was definitely a weird storm....I was fairly bullish on widespread advisory until about 12z yesterday for reasons I had mentioned more than enough times in this thread, though maybe 00z the night before I started to have serious doubts. It obviously produced to our west and often, like you said, that can propagate eastward somewhat even when models are insisting defeat. So there was a chance we'd still get 2-4" or something. I managed 2" but I was a fairly isolated lucky spot.
When you go back and examine the upper air, it becomes noticeable on the really late runs (like inside of 24h) that the inability to pop downstream ridging actually starts to turn the lakes trough from a negative tilt to a slightly positive tilt by the time the trough axis gets to about ALB-PHL longitude....and that's usually not a good thing. It disrupts the mid-level forcing. Previous runs had been trying to maintain a little more neutral. This speaks to the lack of "curl" in the H5 heights underneath or SE of New England.
