May 15th Ponca City, Oklahoma Supercell

May 15th featured a boundary across far southern Kansas into northern Oklahoma. Strong convergence, decent moisture and good shear would set the stage for supercells to form along it. By mid afternoon, storms did just that. One main supercell developed and right turned into northern Oklahoma. Structure was very nice and at one point it even produced a funnel halfway to the ground. The supercell was a prolific hail producer with stones falling as large as softballs. As it moved east, it eventually out ran the instability and weakened near dark. One of the prettier supercell of this year so far, and even though it didn’t produce a tornado, the guests loved it! Enjoy the pics!
