On 9/11/2015 storms rolled in from the north into Huntsville. I was able to capture the shelf cloud coming over Chapman Mountain! I also captured what the untrained eye may have thought was a tornado. Interestingly enough, WHNT’s meteorologist discussed clouds like this and asked if a new cloud type needed to be named. We’ll leave that decision to the professionals.

Does this cloud need a new type of name? We’ll leave that debate to the professionals, but several people confused this for a tornado, but it has zero rotation.
