On July 5, 2022, residents of Sioux Falls, South Dakota looked up and saw something they’d never seen before: the sky had turned green. Minutes later, a derecho — a wall of violent straight-line wind — slammed the city at over 100 mph. The green wasn’t a trick of the light. It was a warning.
Marc Scott narrates this short documentary with the quiet authority of a Discovery or NatGeo feature — unpacking the atmospheric physics behind one of nature’s strangest and most ominous signals.
Narration by Marc Scott
When the sky turns green…
Run.
On July 5th, 2022, residents of Sioux Falls, South Dakota looked up and saw something terrifying: a glowing, green sky. Minutes later, a derecho slammed the city — 100+ mph winds, power outages, destruction.
But here’s what’s wild: that green sky is real science. It happens when storm clouds are so dense, they scatter sunlight through hail and rain — filtering the sky into a sickly green hue.
It doesn’t happen often. But when it does, it usually means something violent is coming. So next time the sky turns green… don’t stop to take a picture.
Frequently Asked Questions
Why does the sky turn green before a storm?
A green sky occurs when dense storm clouds — typically associated with supercells, derechos, or severe thunderstorms — scatter sunlight through water and hail in the atmosphere. The combination of the reddish late-day light and the blue of the storm clouds can produce a green or yellow-green tint. It’s a genuine atmospheric phenomenon and often signals the approach of violent weather, including large hail or tornadoes.
