If NYC can catch the beginning of a transition from ENSO neutral to a developing Super El Nino when it's cold... boy that winter would rock and roll for us. Constant threats of KU storms. It would be a winter Weenie's dream come true.
Interestingly enough, the end of the world won't happen with thunderstorms. It will happen when this planet is too warm to sustain life due the sun's increase in size.
New York City B+
I would have really liked for that blizzard to make a move even 25 miles north and west. NYC would've gotten some amazing, record snow.
