Back in the days when we all had antennas and cable hadn’t been born yet, the static stations were a great thing to watch if there might be a tornado in your area. Apparently if one formed, it would significantly change the look of the snow on the TV and give you a warning to quickly head to the basement. I never actually saw it happen, but there were a couple times we had local warnings and my parents plopped me down to keep an eye on the TV.
