In my inexperienced opinion, it seems like much of the wonky stuff is tied into interaction with the front/trough progressing across the Northeast tomorrow. Too me at least, that accounts for alot of the wiggles back and forth on OP guidance. While both the NAM and GFS sort of weaken the trough and de-amplify a bit, there are some disagreements into how quickly this happens and the extent and that could play a big roll in how far west Lee will get.
If we see see towards the western envelope, I think it's something into extreme western Nova Scotia or the eye just west of the actual land. I don't think we will see a final solution any more west than this.
