Rotation in the wall cloud north of Cheyenne, WY.

August 22nd was a day that showed promise. Two plays existed. You could either play the upslope where better shear was present in southeast Wyoming, or you played the front where better instability and moisture existed. I chose the upslope being much closer to home. By early afternoon, I headed out to play cells that were developing in the upslope regime along the Laramie Range. The first cell was a classic supercell, with rotation and golfball size hail. Low level shear just wasn't strong enough to produce a tornado. Late afternoon, another cell emerged out of a line and developed pretty structure. It was also severe with golfball size hail. Scariest thing occured as I was southwest of Kimball, out of my van and filming the second storm. While taking still photos a bolt of lightning hit a telephone pole about 500 feet away from me and literally jolted me. One of the closest experiences I have had!

What would become the second cell, explodes to my west.	Wall cloud and clear slot from the first storm, looking north.
Rotation was occurring here, but just couldn't make it to the ground.	Second cell looking southwest from Kimball, NE.
Looking west along the CO/NE border.	Nice tilted updraft producing golfball size hail.
Another shot of the updraft and inflow band.	Hail to golfball size covers the road south of Kimball, NE.
