The weather channel loves the wind chill factor because they get to post incredible temperatures and presumably get more viewers. I've seen weather channel maps on cold winter days with incredible low temperatures and I had to look twice to see that the temperatures weren't real, they were factored. Weather experts can't even agree about the WCF formula. It's based on how "normal" people feel the wind on bare skin. Anybody will tell you that there isn't much bare skin on cold winter days and most people turn their faces away from the wind or, gasp, get out of the wind. The wind isn't always blowing nor does it blow at the same speed but the weather experts take the highest recorded velocity and post that number. The WCF numbers are notoriously inaccurate but they are fun so that's what we get.
