Wondering if anyone has any thoughts on the formation to the left of the main storm in the attached picture. I am new to the chasing game and would value any thoughts. Picture was taken to the west of the township of The Rock and is looking towards the WNW with the storm travelling SSW. It appeared to be all the way down to the ground, but by the time I had pulled over and run through a line of trees to get a clear shot it was ascending up into the main cloud. 30 seconds later it was gone. At the time I was asking myself "did I just see the end of a tornado?" Picture was taken with a wide angle lens (didn't have time to change it to zoom into the feature) at a focal length of 16mm.
