Say it with me now: It must be global warming

I was about to lock up and head to bed when I looked out my back door and saw what looked like sand on my deck. So I flipped the light on to see a dusting of snow. We also had snow showers Wednesday afternoon. I have lived here in South Central Wisconsin for 12 years now. Previous to this year, the earliest I can remember snow falling was October 20th or 21st in 1995 (I can remember that because our dorm room Ouija board predicted it, and I had gone to a flick with my wife, who was not yet my girlfriend, when we saw it.) Snow on October 11/12? That's nuts even for most of Wisconsin.
