Started the day in Salina and initially headed toward Pratt. I intended to just stay ahead of the derecho while keeping the Oklahoma suercell as an option. After some indecision, I changed course at Hutchinson and went northwest to intercept the supercell along I-70 at Hays. It was tracking along an outflow boundary, with easterly surface winds and increasing instability ahead of it. I reached this storm at Russell. I stayed ahead of it on the interstate eastbound to Salina. The storm was pushing outflow far ahead, but it managed to kink the outflow a couple of times and spin up some mesovortex tornadoes - at least one of which looked strong. The first one west of Russell I may have seen, but need to review my video. The second one - a big dusty tornado northwest of Dorrance - was very distinct:
I went north to get closer, but the tornado became rain wrapped fairly quickly:
Shortly thereafter, the outflow consolidated as the storm evolved into a 100mph-gust producing bow echo:
I went south on I-135 to get out of the way of this and headed down to Wichita to let the main derecho (not sure if it met that criteria yet) pass over. This was somewhat disappointing, with no structure or haboob on the leading edge. I waited for the stratiform region to arrive so I could shoot upward lightning at the towers in Colwich, but the southern part of the MCS was retreating northward and no stratiform was upstream. I went back north to Newton to try and find some wind turbines or other towers, locating one on the south side of Newton. Two upward flashes happened to it as I approached. One was visible on my dashcam, along with a more distant one possibly from the Colwich towers:
After I set up my main cameras, the storm would not do it again. New storms continued to go up behind the line over Newton. Again, most of this lightning was uncooperative, but I did catch one nice slow positive CG on both a still and 6,000fps high speed.
I drove up to Russell for the night in preparation for the next day's event.
