Storm chaser films as 'mother ship' storm cloud forms in front of them

You can see about 1:40 in the cloud begins its swirl as storm system gets some rotation. By about 2:10, a well defined wall and shelf cloud are visible.

And around 4:10, you're expecting a light to come shining out of the center of the cloud base and a request to be taken to your leader.

Instead, it's just frequent lightning strikes, downdrafts, and the inklings of a tornado.
