Lightning never strikes twice in the same place
As it turns out, it can, and it will. In fact, it can strike twice in the same place within a minute! The Mythbuster guys debunked this myth in a video where lightning goes crazy on a tall building. The video also serves as a good reminder to never stand on the top of a skyscraper in the middle of a lightning storm.
Heat lightning is a real phenomenon
While we're on the lightning tip, let's dispel the myth about heat lightning. The weather geniuses at AccuWeather.com say that heat lightning is "actually a thunderstorm happening a significant distance from an observer." You may not hear the thunder for a number of reasons, like being "muffled by long distances." Heat doesn't cause lightning any more than the Miami Heat cause beers to be $9 at a basketball game.
"Earthquake weather" can predict when the ground will shake
We spoke to Michael Whener, a senior staff scientist at Berkeley, who hears this one. "There's no correlation between the weather and earthquakes," he said. People's memories are selective, he said, and can incorrectly correlate a 'quake with a sunny day or a rainy one. Similarly, rap expert Big Sean makes the claim in the song "Mercy" that when the ground moves, that's an "ass quake." Unfortunately, we found no expert who could comment on whether the weather can effect ass quakes.
Chicago is the windiest city, Florida is the sunniest state
Dr. Greg Postel, a smartypants hurricane/storm specialist who works at The Weather Channel, set the record straight about the famed slogans associated with Chicago (The Windy City) and Florida (The Sunshine State). As it turns out, a number of cities in the Plains, like Dodge City and Oklahoma City, are all windier "on a yearly average than Chicago by a few miles per hour." Plus, the state where everyone's grandma lives isn't that sunny, at least when compared to the Southwest states. "Phoenix gets twice the amount of sunshine per year than Tampa, Florida," said Postel.
