Supercell/Possible Tornado - Trans Pecos Region of Far West Texas

Wes Adkins and myself left Lubbock, TX during the morning of Friday May 22, drove south to Odessa, exited low stratus as we entered Fort Stockton, and then parked 20 or so miles east-northeast of the Davis Mountains in Far West Texas.  Towering cumulus struggled to breach the cap for an hour or two, and then one cell pushed through along a differential heating boundary left by the previously dissipated stratus as an orphan anvil spread northeast across the zone of ascent.  This cell back built toward the Davis Mountains, where it then became anchored to the elevated heat source.  It quickly evolved into a supercell, with the base initially shrouded in rain, but eventually becoming rain free, after-which a skinny funnel developed (but failed to make contact with the ground).  We watched this supercell sit over the Davis Mountains for another hour or two, and then departed back north toward Lubbock.
