The AI-GFS is 54 hours of light snow and it works because it acts more like a classic Miller B and the coastal low forms that helps drop that extra precip, that's why it's ~5-10".
It was poorly communicated hyperbole, but you get my point, it probably isn't going to happen unless we get 4 consecutive substantial positive changes, whether that is in regards to where the ULL digs, how quickly it tilts negative, etc.
