LOOK: Unbelievable Green Sky Over Sioux Falls Before Storm
Why Was the Sky Green in Sioux Falls?
Just prior to a large storm system rolling into Sioux Falls on July 5, 2022, the sky turned a creepy, ominous green. It was a truly weird experience. Old folktales say that a green sky is a warning for a tornado and/or large hail. But, that's not necessarily true.
The green sky we saw in Sioux Falls Tuesday night was caused by light from the sun being refracted by the hail (AKA ice) up in the storm clouds.
"[S]unlight behind the thunderstorm is attenuated and scattered by the rain and/or hail shaft to yield a bluish hue. If this thunderstorm occurs around sunrise or sunset, when the sun takes on a more red/orange/yellow look thanks to a longer trip of the sun's rays through the atmosphere, that thunderstorm could instead look more green." - Weather.com
Thanks to these folks, we can see what it was like Tuesday evening. They took some pics and we thought we'd share...because some things are simply unbelievable. Thanks for sharing!
