If New York is truly going to be as clear as what I just saw in the forecasts (unlikely, it's still 10 days out), then this will be where a lot of people will be coming.
The forecast I just saw for Syracuse (the closest big town to New York City for totality) is 0% high clouds, 0% midlevel clouds and 1% low clouds at 2 PM, about an hour and a half before totality.
