Meteorologist Corey Martin stated that the unusual green color of the sky has a very simple explanation. Thunderstorms hit the state later in the evening, so the reddish hue of the sunset sky blended with the blue water droplets in the storm clouds.
“Thunderstorms usually occur closer to the evening when the sky takes on a slight red tint as the angle of inclination of the sun slowly begins to approach the horizon. Particles in storm clouds with significant depth and water content will mainly scatter blue light. When the red light scattered by the atmosphere illuminates the blue water/ice droplets in the cloud, they glow green,” he explained.
The scientist also added that to achieve this effect, a very high water content in the clouds is required, which indicates the presence of a large amount of ice. The unusual phenomenon is a visual warning that a thunderstorm could produce large hail.
At the time of his report, Martin said hail was known to occur in Sioux Falls, but it was not very large.< /p>
Pics of green sky from my family in Sioux Falls have been incredible! Take a break from 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
