Meh could be noise, could be ridding of the extreme wrn outliers too. I mean an area near the Quabbin could have been 10.5" on the 00z run and get into the light purple shading and now is 9.7" on the 6z run and stay in the blue.
Should be mostly dry snow except maybe SE cstl areas for a time. Even here it may get near 32 and a little wet before dropping later in the storm. 128 on N and W probably teens for a time.
Well it threw more QPF into NNE, but ever so slightly trimmed the line where >1' QPF falls. It could be noise, but it could be the goal posts narrowing a bit. Overall those are small, but good trends for now.
I definitely don’t like a de-amplifying s/w as it approaches. Not usually the best for big snows, but on the other hand if we had that, it would be congrats Montreal and Ottawa.
The ridge near the Davis Straits certainly doesn’t move IMO, so it does act like a block. The 50/50 low does move out like Will said, but it does its job.
