Northeast Colorado Supercell - 20 May 2014

I observed a beautiful supercell with Crystal Kerber during the evening of May 20th.  We were heading west toward Limon, CO in order to be in position for a storm chase the next day, and as luck would have it, a supercell was moving southeast along I-70 between Denver and Limon.  At 630pm MDT, we reached Seibert, CO as the supercell moved east of Limon...we then headed north a few miles on highway 59, set up the tripod along the side of the road, and were treated to a text book perfect high plains supercell.  The storm went through several updraft cycles, eventually developing a helical look to its structure as it approached our location.  We eventually moved south out of the path of a hail core, then went west a few miles to watch the last rays of daylight strike the backside of the storm.
