The reason I'm so quick to go with the northern solutions is that this system doesn't necessarily make as much sense to go south as the last one did. With the last system, there were a lot of things like the shearing out behavior and deep snow to the SW that supported a significant shift south, and it made sense. But with this system, it's coming from a different direction, it's much stronger and the snow out NW isn't nearly as deep or widespread. It makes decent sense this storm is doing what it's doing, at least to me. A south shift this time doesn't make nearly as much sense.
