6/13/2014 Crook County, WY Tornadic Supercell

6-13-14 featured a strengthening surface low-pressure with marginal dewpoints on the northern high plains.  We (Laura, Walker and I) sat near Devils Tower (Wyoming) watching a strengthening supercell that would eventually become tornadic.  We stopped along WY HWY 24 to watch the surging rear flank downdraft cut a tornadic circulation just to our northwest.  After the supercell began to merge into a multicell cluster, we pushed east to RAP where we met up with Walker's brother and nephews to watch mature convection push into the Great Plains.
