Happy Monday and welcome to another edition of the Beyond The Forecast newsletter!
Social media was buzzing last week when a derecho in the Upper Midwest caused the sky to turn a green hue near Sioux Falls, South Dakota. Eerie looking!

Why did this occur? Well, it’s all about what time of day the storm happened and what size hail it was producing.
Here are the hail reports from South Dakota and Nebraska from July 5th. Golf to softball-sized hail was reported!
You can also measure the size of the hail by diameter. Golf ball hail is about 1.75″ across, while softball-sized hail is 4″.
You can tell the hail was quite large!
The storm happened later in the day when the sky usually starts to take a reddish hue for the sunset.
The red light was scattered by the large hail in the thunderstorm clouds, causing a green sky.
Theoretically, it would be possible for us to see this phenomenon in Virginia. It would require the precise timing of a large hail-producing thunderstorm close to sunset. How cool would that be?!
Switching gears to your forecast, it is feeling SO nice outside as we’re getting the work week started. Meteorologist Chris Michaels is tracking when summer heat and storms return in our daily forecast article.
