Residents in Sioux Falls, South Dakota, witnessed a bizarre phenomenon in the skies earlier this week. On Tuesday (July 5), locals in the city were amazed as the sky above them resembled a scene you'd expect to find in a sci-fi movie. Speaking to the <a href="https://www.dailymail.co.uk/sciencetech/article-10988845/It-looks-like-Stranger-Things-Haunting-green-sky-appears-Sioux-Falls.html" target="_blank" rel="noopener">Daily Mail</a> about the incredible sight, AccuWeather meteorologist Isaac Longley said: "While it is relatively common to see these green skies, especially in the Plains, the skies associated with the severe storms that pushed through Sioux Falls during the afternoon of July 5th appeared even greener than normal. "This, of course, caught the attention of many who had never seen skies so green."

"As many of us know, the sun appears redder later in the day as it approaches the horizon. However, light underneath a tall thundercloud appears blue due to the scattering by water droplets. "When the blue light is illuminated by the red light from the setting sun, it appears green, which is why some thunderstorms have that greenish hue to it." Longley added that the green skies were visible for around 10-20 minutes. Taking to social media to share their thoughts and images on the green skies, one resident tweeted: "The Green Monster over Sioux Falls yesterday. The most eerie storm I’ve ever witnessed."
