This is very brief with a more detailed account to be written later on next week. My chase partner Robin Lorenson and I left Salina, KS about 8:45am for a target somewhere around Sidney, NE to Sterling, CO. We missed the La Grange, Wyoming 25-minute tornado event by about 30 minutes. We were simply late. Other storm chasers had the same fate as I’m finding out (including Bill Hark, who we chewed the fat with for probably too long in retrospect in Sterling!! 
It was great to catch up with you again though, Bill!). However many others were not late, who were already up along I-80 in the early afternoon — including Vortex-2. Some fine High Plains storm photography, though, ensued as we followed the supercell as it evolved over the next several hours from south of Harrisburg to north of Dalton to southwest of Oshkosh by late-evening twilight. Below are a few images from this chase:
Mike,
Nice shots there! We were also late…very late. We didn’t get to this sucker until it was between Harrisburg and Dalton. Indecisiveness or poor/slow decision making on our part, as well as a lack of data in the field, prohibited us from making it to this storm quicker.
Still, we followed this storm from that area northwest of Dalton, NE, out towards Oskosh before it collapsed, and the stuff to the east became the dominant storm.
Incredible! This is only my second time chasing, and the first time having ever seen something like this!
It was great meeting you again. Thanks for the help out there over the last few days.
Hope your Chase-cation goes well!
Charles

Thanks Charles! I’m glad to hear that at least you made it to the storm between Harrisburg and Dalton… it was funny driving into Dalton since it reminded me of you and wondering if Charles Dalton was chasing near Dalton, LOL! It was good to see you and help nowcast a little bit, sorry I couldn’t do much more than I could. -Mike U
