I dont think so. They may be rarer. But warmer water is going to cause some wound up beasts in the future. Hell it might even happen in March. I basically think winter is over. And the pattern isnt looking good for it. But you never know when you can get a phased up bomb with just enough cold air to make it work.
The major change I am seeing lately is that the 4-6 inch storms we do get are gone within 48 hours. We just cannot sustain temps below freezing anymore.
