Chase Log: I didn't write up a full chase log right afterwards and I don't recall a lot of the details as it was a pretty messy day. We started by going to Enid, and then saw storms forming southwest of there.
We intercepted the supercell near Canton, where we saw a brief multi-vortex tornado at 3:20 pm. Continuing to follow the storm, we also saw the rope-out stage of an elephant trunk tornado near Fairview at about 3:48 pm. Unfortunately my pictures didn't turn out very well as the rain was starting to fall and my camera was having trouble focusing. That and I was busy trying to call in the tornadoes and plot our next route.
There wound up being storms pretty much all over, and things quickly got crazy, so we didn't stay out chasing too long. The high risk was certainly warranted. Sadly, there were many large, destructive tornadoes that affected many cities from Kansas to Texas.
