Well, I grew up in Orange county, my dad commutes 1.5 hours to NYC daily so i do feel for you.
Other areas I have been to and liked were Dover DE which has a nice laid back attitude, a little warmer weather and much cheaper cost of living. I like just about all of southern NM, but that is a heck of a move for a NYer LOL!
What I have heard negative about VA beach, from my SIL who currently lives there (and I have visited a few times myself) is the traffic, the crime and the overall mentality of the majority of the people there. She grew up for quite a bit of her life in Orange as well so I think it is a cultural issue.
NC my cousin in law lived there 4 years and absolutely hated it. Both for educational level of a lot of the people there and the fact that it was just way to slow there for her. She also grew up here in Orange.
Have you ever been to Vegas? Not for the casinos but to just visit? There are a few nice towns in that general area and the weather is pretty nice. Might want to go over on the NV forum to get some more opinions. Being a military wife, I have been there a few times and a lot of our dear friends lived in Vegas for a few years at a time. There is more to the city than the strip. I actually found an awesome Italian deli there.
I can really feel for you about the weather. Sometimes I feel like I can't take another winter here!
But make sure that wherever you move remember that there are few places that offer as much as Southern NY do. There really is a high quality of life here that you don't get in too many areas.
Did you know that some areas of CT are a couple of climate zones warmer than downstate NY?? DE is a few warmer too.
Just brainstorming out loud, good luck with your decision!
