I had snow on Christmas eve which turned into rain late at night. I wasnt expecting it to turn back to snow until late Christmas day for a few hours.
I remember turning on TWC with Paul Kocin and he was mentioning how the storm off the coast is bombing faster than modeled and the rain will turn to wind driven snow for the NYC area and that's exactly what happened. My family was stunned when they went outside and they had to travel home.
