Katie Burtis and I observed great structure with the picturesque Julesburg supercell. We initially I targeted near Sidney, NE to start the day watching a couple of towers struggle early on in the vicinity. Met up with Bob Fritchie and Steve Vanderburg here and decided to intercept the cell which had been pulsing near Bridgeport. We soon found a nice view of the updraft region with a decent wall cloud developing NW of Dalton. However, a fairly cold RFD surge quickly wrapped around and squashed any tornadic chances. After observing a few additional RFD surges, we decided to head south for some structure opportunities and was pleasantly surprised at what this storm had become. Very photogenic striations developed as we neared Julesburg with laminar tail eventually feeding in as sunset approached. The lower light angle produced vivid color saturation on the west side of the tilted updraft region. Also of interest was the development of eddies rotating around the outskirts of the meso. Possibly some Kelvin-Helmholtz activity?
