This was an on-the-whim chase. An OFB set up across north-central Oklahoma, which, in combination with very strong instability, I thought provided at least a chance for a brief spin-up tornado (high near-surface vorticity + strong low-level instability = chance for non-supercell tornado). A supercell south of Enid did have a pretty nice low-level couplet/mesocyclone for about 15-20 minutes, but the storm quickly became outflow dominant as cold outflow undercut the updraft. We watched a weak wall-cloud south of Enid before calling off the chaes and heading to the Pizza Hut in Perry.
