As someone as experienced as you are, I'm sure you are acutely aware that even the best weather models disagree with one another over time, strength and precise location of a storm. No model will give you the exact LAT/LONG for a landfalling Nor'East, hurricane, or even a Nor'Easter in January.
The idea that this storm is going to impact New England the most is dead. Long Island/NYC points south are going to be the highest impacted from this storm. The NWS is dropping the ball on this completely.
