This was the ceremonial end to the 2018 storm chase season. Emphatically it was finally over, with few really great highlights in what was one of the quietest/least productive chase seasons of the past two decades.

Still, this day promised the possibility to grab a tornado intercept at the end of the season, with supercells forming over the high terrain of New Mexico and Colorado and spreading east/south into Oklahoma in the evening. We ended up with supercells initially — but storms quickly grew upscale into an MCS that accelerated forward, with derecho criteria met by this line as it moved S and E.
