After resting for a day and a short drive from Rapid City to Chadron on May 25, I was ready for another chase. Conditions were marginal but there was still the possibility of supercells and tornadoes east of the mountains in Wyoming, western Nebraska and eastern Colorado. There was decent upslope flow and moisture to trigger storms. I targeted northeastern Colorado but I was a bit slow getting ready and leaving Chadron. I also did some landscape photography along the way and enjoyed the beauty of the high plains. The cap was low and storms fired early especially near Denver. Not much was happening in the Nebraska Panhandle. I drove west from Chadron to avoid some construction, then south and west through part of Wyoming. There was an isolated storm near Sidney but it would move into an area of very poor road network. I finally decided to target a persistent slow moving supercell northeast of Denver. I drove south. By the time I reached Stoneham, Colorado, my targeted storm was dying. There was a new storm farther to the south that had become tornado-warned. It was too far to reach. I continued south to I-76 near Brush. Visually, my storm was becoming more organized. I had been considering ending the chase but decided to go slightly west and north to watch the storm. It was just north of Fort Morgan and briefly had a wall cloud. I watched it for awhile, then backtracked south and east so that I could again look at it closely from another north road. The storm briefly intensified and developed beautiful striations. The sun was setting and I was able to obtain some nice photos. I ended the chase at dark and headed to Sterling, Colorado for the night. No tornadoes, but beautiful storm structure.
