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.
