July 15th/16th Nebraska and South Dakota Tornado Warned Storms

July 15 and 16 took me to northern Nebraska and South Dakota to play storms along the dryline. Shear wasn't expected to be very strong, but enough to help generate supercells, and to my surprise tornado warned supercells. July 15th took us to Nebraska where a large supercell developed west of O'Neill. This storm was fairly high based, but rotating nonetheless. It produced golfball sized hail and had very high winds once it lined out. July 16th took me to central South Dakota along the Missouri River where numerous severe storms formed near dark. Lightning was decent and the hail was large, also to golfball sized. Click on the pic for a larger image.
