N1 - Funding Information:
Acknowledgments. We thank the countless VORTEX2 PIs, students, and other participants, without which the project would not have been possible. We are grateful for the generous support of VORTEX2 from the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration. The data collection and analysis were supported by NSF Awards ATM-0801035, AGS-1157646, and AGS-1536460. We are especially thankful for the assistance of Josh Wurman, Karen Kosiba, and Paul Robinson in collecting and analyzing the DOW data.

We are especially thankful for the assistance of Josh Wurman, Karen Kosiba, and Paul Robinson in collecting and analyzing the DOW data. The DOW radars are NSF Lower Atmospheric Observing Facilities. Don Burgess graciously provided NOXP radar data. Radar data were edited using the SOLO3 software provided by the Earth Observing Laboratory at the National Center for Atmospheric Research (NCAR). Radar data were objectively analyzed using software originally written by David Dowell. The photographs in Figs. 11a and 11c were provided by Owen Shieh and Jim Marquis. We also thank Skip Talbot for providing video of the storm. Last, we appreciate the selfless donation of time and constructive critiques provided by the reviewers (Johannes Dahl, Matt Parker, and one anonymous reviewer).

N2 - The 12 May 2010 supercell thunderstorm intercepted by the Second Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX2) is analyzed during a time period of strong low-level rotation in which dual-Doppler radar observations were collected. Two different cyclonic vortices are documented. The first vortex was ''marginally tornadic'' before abruptly weakening, following the development of a descending reflectivity core (DRC) similar to those that have been documented in past studies of supercells. The second vortex rapidly developed immediately north of the DRC shortly after the DRC reached low altitudes, and was associated with a tornado that produced damage near Clinton, Oklahoma. The paper explores the possible roles of the first vortex in triggering the DRC, the DRC in the subsequent initiation of a new updraft pulse on its flank, and the updraft pulse on the development of the second, stronger vortex. The Clinton storm case is, unfortunately, a nice example of the challenges in predicting tornadogenesis within supercell storms even in environments understood to be favorable for tornadoes.
