Navy appears to have shifted west, at h5 it has a closed off low and 2 closed contours instead of only one. Rule of thumb is a foot of a snow for each closed contour (Bernie Rayno talked about it on his livestream, the Euro actually had 3 closed contours). Interestingly the gfs has 3 as well as it goes over the cape and 5 downeast Maine (so it’s surface output is likely bullshit verbatim). The Canadian has only one, which is why it makes sense that the snow totals are lower on that. Nam has 5 closed contours as it crosses over nantucket. Euro last night had 3.
