Usually, the weather is a subject for polite, uneventful conversation with people you don't know very well. But sometimes the weather is weird, or even downright scary. Here are a few examples of weather events that gave neighbors more than enough to awkwardly discuss.
1. Dramatic Changes
Midwesterners are accustomed to using both their heat and air conditioning in the same day due to dramatic temperature changes and unseasonable weather. The "Great Blue Norther" of 1911 was the most dramatic cold snap ever recorded—several cities set record high and low temperatures on the same day. On November 11, 1911 (yes, 11/11/11) a massive storm system separated warm air from arctic air, yielding violent wind and storms. Kansas City, Missouri reached a high temperature of 76° F (24 °C), and by midnight, the temperature plunged to 11° F (-11 C°). The 65 degree difference was replicated in Oklahoma City and Springfield, Missouri.
