How this for a photo op!
When I was younger I had a dream about being a storm chaser! I blame it on my Dad as we used to watch lots of documentaries on Twisters.
This is a supercell formation. Now according to the wonderful peeps at wikipedia if the wind forms an updraft it can then start spinning and form a twister.
There was a film that is specifically about a supercell but I can’t remember what its called lol! I watched in with my Dad and the supercell cloud actually drops lots of twisters rather than just the one.
