Started in North Platte, NE after forecasting. My morning target was Brush, CO. (I like to pinpoint just for the fun of it). Heading west, we watched the storms developing and putting down hail in Denver. Eight miles west of Last Chance, CO, the storm organized into a beautifully photogenic supercell. This storm produced a number of funnels. Nearing sunset, we headed north and after emerged from the rain to be treated to several rainbows, including a double rainbow. Then, just a few minutes before the sun set, the collapsing storm produced a jaw dropping mammatus display.
A delightfully fun chase with an isolated supercell on the dryline NW of Ogallala. We chased this storm through Arthur, Keith, and Perkins counties, staying just ahead of (most times), the hail core, that was dropping quarter sized hail. One funnel and a short-lived gustnado later, we were treated to a gorgeous sunset mammatus show and one of the best light shows for a long time. What a treat!
