May 25th Western South Dakota Supercells

Decent upslope flow into the Black Hills, along with good moisture and moderate shear, would set the stage for several supercells to develop and move east from the Rapid City area. Structure was quite nice with each of these storms as they spun across the countryside north of I-90. One storm tried hard to become tornadic, while the rest were quite prolific hail producers.
