There's a snow storm in our forecast, due tomorrow afternoon. Not a very big storm, mind you, just six inches (15 cm) or so. But my grocery store was completely mobbed already at 7:00 AM today, and the checkers told me it was worse yesterday. There really isn't any reason to rush to the store 48 hours before a storm hits. I think people rushed to the story two days early to beat, not the storm, but the pre-storm panic buying. They are afraid, not of the weather, but of the pre-storm crowds. So, meta-panic buying.
