Correction: Originally, we referenced Jerry Bruckheimer, who is known for his special effects in his movies, but he has not done a movie about aliens.
The sky around Sioux Falls before the severe weather was green. And not a light green — the green that would be the color of the sky before aliens arrive in a movie. Or before the Wicked Witch of the West threatens Dorothy and her little dog, too.
Weather watchers around Sioux Falls took to Twitter to share photos of the creepy and ominous sky, while we took to the internet to try and find out what this green sky means.
Do green skies mean a tornado is on the way?
Green skies often come with severe weather, however that does not mean it’s a tornado specifically as there isn’t a direct correlation between the two, according to AccuWeather.
Why is the sky green in bad weather?
It’s not completely decided why green skies occur, the Scientific American reports. However, if a thunderstorm occurs during a time of red light, like a sunset, the water particles in the air can make it appear as if the sky is slightly green in color, some researchers say. The gray cloud of a thunderstorm, water particles that bend red light to appear blue and ample red light in the sky can create the perfect storm for a green sky.

User Jaden (@jkarmill) caught the sky looking something akin to neon green.
A meteorologist on Twitter posted a photo of the green sky and a graphic explaining the phenomena he created.
Pics of the green sky from my family in Sioux Falls have been incredible! Had to dig up this fun green cloud infographic I made back in the day. Hail reports not too large at the moment, but storms are very moisture loaded in this warm, tropical environment. #SDwx #IAwx pic.twitter.com/S39JLSRfEu

In this video, one person compares the sky to the "Wizard of Oz," the other to "Stranger Things." (Warning, there is a cuss word.)
Even a meteorologist from Virginia took notice of how green the Sioux Falls skies turned.

Of course, a Sioux Falls weather reporter took notice.
