I'm pretty sure you can take the bus from NY to Burlington Vermont - from there you can go to places like Sugarbush, Stowe and Mad River Glen, all amazing ski resorts which have great snow right now and will have good spring skiing in 2 weeks time.
You can also take a bus to Montreal (direct from NY with either Greyhound or Trailways NY) and from Montreal there are about 10 mountains all within 2 hrs
