I don't consider the Catskills to be part of the NYC area. Yes the Catskills are N&W, but so are the Adirondacks. I was referring to more like Sussex County NJ or Orange and Putnam, NY.
This storm looks to be for Wayne, Pike Cos. PA to Sullivan, Ulster, Greene, Columbia Cos. NY, to the Taconics and Berks etc... Dutchess could have a significant gradient I think... with a 0-2" low along the Beacon waterfront to a max somewhere along the NE corner in the Taconics.
