As I write this, the southeast United States is bracing for a winter storm, at least by our standards. You know what that means. Many people have rushed out to buy bread, milk and eggs. Some colleagues like popular TV meteorologist Brad Panovich even use a "Bread Meter" to convey the level of winter weather threats to viewers. The "bread, egg and milk" thing has always fascinated me because I know everyone doesn't suddenly get a craving for french toast at the mention of a snowstorm. I currently live in Georgia, but I also noticed this same tendency when I lived in the Washington D.C. area. Why do people buy bread when snow (or inclement weather) is in the forecast?
