I was there this past weekend and saw the snow fall in three places while there. Once on main street, once at IASW and once while seated for Fantasmic. I am assuming that it doesn't snow at ROA when there is not a Fantasmic performance, but I could be wrong. We had watched the fireworks from our premium viewing seats and it snowed from the show's light tower above us. It snowed when we were seated for the parade near IASW, but not during fireworks, just right when the parade ended.
