Depends how warm it is. I would take SNOW over 40-degree F rain, but I'd take rain if it was one of those warm, summer showers...
Constant snow can be depressing though; I lived in Erie for a year, and sometimes it would snow that fine, lake-effect snow for a week at a time. I would go to work in the dark, snow, and leave work in the dark, snow, and go home. I drank a lot during that time (I'm not really kidding).
