Ragged Updraft Base

The updraft base is as ragged in this shot as it was smooth in the last picture. A wall cloud is visible above the clump of trees on the right side of the image and it was obvious that this storm was well on its way to outflow dominance. Taken east of Pesotum, IL, September 21, 2012.
