If I knew the answer to that. No the models know better than we humans do. But I will say that historically it's gone both ways. And it's also possible they'll bring back and less magnificent storm of 1-3,2-4, 3-6" or so or that we'll remain in the outer snowbands with a lighter/wetter snowfall. We need the ridge out west to stay stronger and leave enough room for this system to get wrapped up the way some of the models earlier depicted it. On most of the 00Z runs the top of the ridge was flattened making for a more progressive flatter trough in the east. As long as the AI models have this thing IMO it's a legitimate threat.
