Interesting set up this day. Another boundary lay east of Denver with a nice winds shift and pseudo-dryline running from Ft Morgan to Limon. Air to the east was very moist and unstable. By mid afternoon isolated storms developed on the boundary. They started fairly high based as shown in the first couple pics below. As early evening arrived, the bases lowered as temps dropped and the dews rose. A nice supercell developed west of Limon and tracked north, then east across Lincoln county. This storm had awesome structure with a nice vault, shelf, tons of CG and even a small landspout tornado. By dark the storm weakened as the atmosphere stabilized, but not before leaving an incredible image etched in my mind.
