I wouldn't be that surprised if the NYC area and North of I84 got similar snow amounts though because it will depend on where the frontogensis is ahead of the mid level warming and where/if that dumping band sets up. Whatever falls will definitely have a better chance of sticking around north of I84.
Thats not me predicting big snow for NYC area, I don't see anyone seeing more than 1-3 inches in this subforum in this setup due to the mid level warming.
