Has anyone else ever experienced snow lightning? It had snowed a couple feet in Illinois one year and I was looking out my window that night. All of sudden a blinding flash of white light beamed through my window blinding me. I panicked thinking "This is it! This is an alien encounter!" A few seconds later my vision came back to me and I turned to my computer to look up if lightning could strike in a snowstorm. The light refracts through the snow.
