Central Oklahoma - Supercell - 5/30/2013

I chased a supercell that moved from Chickasha to east of Purcell with Sharon Austin on May 30th.  This storm displayed interesting structure throughout its lifespan, but it failed to produce a tornado multiple times during the chase. Things got really interesting as the supercell moved over Purcell.  A big wall cloud developed underneath the base, and midlevel updraft rotation intensified greatly as the cell drifted east of I-35.  The structure was at its best during this time, but similar to every other meso cycle, low-level rotation wasn't sustained and the storm weakened.  We were contemplating dropping south to another supercell near Pauls Valley, but decided we were too far out of position to make that happen.  Sharon's brother in law did make the jog south, and his car was nearly totaled by giant hail (last picture)...we probably made the right decision not to core punch.
