July 12th was a surprise for me. I didn’t think there were enough ingredients for a significant supercell event. I was wrong, and happy I was at that! By late afternoon a storm came off the Laramie range and produced a great lightning show. Just north of that cell, another beautifully structured beast formed and became the storm of the day! There was major motion under the updraft base/wall cloud and I was surprised it was never tornado warned. It was severe and produced signficant hail to tennisball size.
