Shelf Cloud over West Phoenix 2014

This storm moved up over the White Tank mountain range in far West Phoenix (see deviation: Shelf Edge) and into my area very rapidly; this is one of the many images of it I got of it. This was the grand finale of the August 19 storm event.

I apologize for the low resolution of this image. I seem to have misplaced the original file and need to find it- it has to be on one of my drives. Until I find it, this will have to do. Sorry about that!
