I wouldn't put specific amounts out until tomorrow evening and just note "potential for a significant winter storm is increasing for Saturday" etc and that what we get is most likely to be snow. There'll probably be a big have/have-not difference like these storms normally give, NYC is in a tight spot like in most storms and hyping big amounts up can still backfire. There's still time tomorrow night or Thu or even Fri to discuss big amounts if models continue the trends.
I remember the debacle around the 2/8/13 storm and the insane NAM run Channel 4 literally put up on screen, and the Armageddon like hype before 1/27/15. It really does make people less likely to pay attention before one really does hit.
That said I have no idea what Lee Goldberg or anyone else is saying since I don't watch them anyway.
