July 12, 2009 Eastern Wyoming Supercell
Last Updated on Monday, 04 January 2010 13:21 Written by Roger Hill
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.

First storm was highly electrified. |
Wall cloud, moderate rotation and this CG made this a nice storm. |
More CG with the initial cell. |

Wall cloud forms and had significant motion. Notice the dense core to the right (looking west). It was producing large hail. |
Storm blew itself out and was in a weakening state here. |
