Intercepted the first supercell of the day in Calhan, CO. A large mesocyclone was positioned over the small town 1. and soon after, a small dust whirl formed and lasted a couple of seconds before dissipating. Just after the dust whirl dissipated, a long stretched funnel became noticeable over the area where the dust whirl was observed.2.; 3. This supercell moved into an area with no road network, so I eventually broke off the cell to intercept another supercell near Delhi, CO that produced hail close to baseball size and contained decent cloud base rotation. I never observed the cell produce a tornado, but the structure made for some beautiful shots near sunset.4.; 5.
I must also extend my appreciation to Dave Lewison for his excellent nowcasting.
