Storms of 2013 - Jeff Frame
Spectacular South Dakota Supercell

Spectacular South Dakota Supercell

The supercell we had followed from near Sturgis to east of New Underwood, SD, now exhibited spectacular structure at low and midlevels. Although an RFD cut formed, it was never close to producing a tornado, but that is not necessary with a storm like this. Taken May 25, 2013.
