That’s a bit of a tough call but at the moment JFK weather starts to get much better Sunday morning. I also believe the inbound equipment for that flight actually comes in from ATL. A change in track east for the storm could could create a major snow event for Long Island but at the moment a bit of snow during the day on Saturday quickly turning to rain is all that’s forecast. If that flight could not depart for JFK Sunday afternoon one of two things would happen. They would lay the aircraft over in STT and use it for a extra section Monday morning or they will run the flight to ATL and connect the passengers from there.
