This was a fun chase day, with a bonafide tornadic supercell to observe at Fleming, Colorado (east of Sterling). The best pics off of the Canon cameras are in the group below. They are followed by the iPhone images and radar screenshots, with a semi-detailed chase account.<\/p>\n\n\n\n

The first six images below in the Canon group are of the first supercell, from about Fort Morgan to Woodrow, on Highway 71 south of Brush. These are followed by the Fleming supercell shots.<\/p>\n\n\n\n

Two supercells were intercepted on this chase day. Wind shear was excellent, with rotating updrafts moving to the southeast. Upslope flow in northeastern Colorado was moistening up some, finally. Dews were solidly in the low 60s. SPC showed a brown 5% tornado risk.<\/p>\n\n\n\n

We had a semi-late BBQ lunch at Greeley, and as we made our way eastward along 34 a massive cumulonimbus cloud materialized a little bit to our ENE. We caught up to it near Fort Morgan, and dove south on 71 from Brush in order to get into position ESE of the storm base. A smallish sculpted updraft was nicely separated from the forward flank precipitation core to our WNW. It struggled as it approached Highway 71.<\/p>\n\n\n\n

While watching the supercell and its hail core approach us, a little north of Woodrow, a vehicle stopped. The big and burly driver (above) asked me whether continuing north on 71 was a good idea or not. I told him that large hail was with the storm and it was not a good idea to proceed! We then started chatting about storms, and he mentioned that he had been in a tornado at Spencer, SD. He was not really interested in being in another one. This person looked a little familiar to me, and I told him that I think I was standing next to him about 28 years earlier! His name is Doug Clayton, and he is a survivor of the F4 tornado that went through Spencer on May 30, 1998. The two of us, and his brother, were interviewed by ABC in Spencer two mornings after the tornado. We are at about minute 8 in the YouTube video below.<\/p>\n\n\n\n
