Yea maybe I still like Bronx Zoo best because of it's central location in the Bronx.
Van Cortlandt Park/Woodlawn/Riverdale area is definitely the coldest in the city. It even seems like it did better than Westchester along the sound. I technically live in Westchester but am a few blocks from Van Cortlandt park and have sometimes stayed snow when places like New Rochelle, Larchmont have mixed.
