May 6th featured an approaching shortwave trough, with great shear, but very limited moisture.  Upslope flow into the Laramie range in southeast Wyoming would result in several storms this day. One high based supercell formed and was quite electrified.  It never produced much in the way of severe weather but looked pretty and was nearly stationary on the mountains. The lightning it produced was quite photogenic.
