I've been meaning to make a video and post it here for the longest time offering examples of light-moderate-heavy snow conditions. I still have the video and will eventually get to it. To give you an example of true heavy snow, since you are familiar with the area think of the used car lot on the corner of (North) Oxford Valley road to the Marquee where Target is, I went down to that area during the 2011 storm to capture video and the marquee wasn't visible. That is heavy snow.
