The prospect of a tornado is scary. But that anticipation gets downright creepy when a green ambiance settles in the skies ahead of time, coloring everything it touches with its unnatural hue.
Some people, particularly residents of the Great Plains or Midwest, think that green skies mean a tornado is sure to follow. In short, that’s not true: The two don’t always appear together. Since meteorologists don’t see the phenomenon as a reliable sign of tornado development, how it happens hasn’t gotten a lot of research. “Let’s say the sky turned hot pink every single time there was a tornado,” says Makenzie Krocak, a research scientist at the University of Oklahoma Center for Risk and Crisis Management. “Then we could look into it as a forecasting detail.”
