Chase Area: Eastern Oklahoma
Scott Currens and I were on the storm moving east from El Rino into OKC. This storm was disorganized at the low levels and after it went into OKC, didn't appear to be worth staying on, despite the media hype. So we drove east to another storm near along I40 north of Ada, OK. This briefly had a nice wallcloud with rain free base, however it eventually got undercut. We dove south to a very nice supercell near Ada with good rotation at cloud base as well as the entire storm.

The structure was great, however, we were too close to get a shot of the whole updraft, thus I've merged two images together below.
