Tornado Warning at Denver Airport

By -
A tornado warning was issued for the Denver Airport. These photos provided by my compadre Michelle Strecker and her husband, Jeff. You can see the rotation in the cloud below.
Storms with large hail often look green as this one does under the shelf cloud.  Note there is no one on the airport ramp. They are evacuated due to the threat of lightning.
There were several reports of hail between 1 and 1.75" in diameter. Here is what it looked like on radar.
