Today was one of the first significant storm days this June that I was available to spot/chase. The chase started with three supercells in the vicinity, the middle one around Ft. Lupton looked the best so that was my target. The southern cell was over work and it didn’t look that great although it ended up having incredible structure over Limon and Eastern Colorado. Soon after I started Northeast out of Aurora the cell went tornado warned. About 45 minutes later a tornado formed out of the SW side of the storm–a long elephant trunk style tube. I watched it as I approached stopping to take a picture every now and then.
After the supercell was mostly dead, I had a choice to attack the line of storms to my south. One cell had consistently put out tornado warnings in Elbert County and it had a brilliant velocity couplet, but that would require a bit of a corepunch which is risky with such high lapse rates (i.e. big hail). Looking NW, I saw a nice supercell with great structure so I decided to check that one out. I knew that it would likely die as it hit the cold outflow of the line of storms to the east, but given I was aiming for structure shots this seemed like the best option!
