May 11th and 12th promised to be decent days. Decent moisture and instability were present, along with good shear. However a fairly stout cap was in place on the 11th, which was much weaker on the 12th. We intercepted a briefly tornadic supercell south of Woodward, OK on the 11th and then a monster HP beast near Clinton, OK on the 12th. The 11th’s storm was a wet LPish type supercell with pretty structure and a weak tornado not far from Strong City. The 12th’s supercell produced a tornado east of Clinton that we weren’t able to see, however the HP’s structure was quite nice.
