The first day of Photo Tour #3 took us to northeast Wyoming to chase the upslope play into the Big Horn mountains. Storms formed early afternoon and struggled to come off the higher terrain for a couple hours. A very low hanging, rotating wall cloud occurred west of Buffalo, WY and produced a 3 minute weak tornado on the top of a mountain! Quite the sight to see! As the storm came off, it became a pretty LP supercell and spun to the southeast, south of Gillette, WY. It eventually dissipated as another supercell formed north of Casper, WY. This cell was rotating nicely and produced a couple of funnels as it moved towards the flat lands east of town. Structure was nice as it persisted well after sunset. A fun day for the tour!
