Got a few shots of a storm that developed here after some earlier and quite spectacular convection towers with pileus caps that collapsed sweeping up another storm, this one. These can be nasty and we were spared the severity with this one as it rolled over town. I had been adjusting ISO between 100-400 and found best results were at 100. It was tricky to shoot because it was just on dark. Any thoughts or cc would be appreciated. Just to give you an idea of scale, the mountains in the background are 4000 feet high. Thanks, Chris.
