Wider weather episode

A progressive cluster of thunderstorms developed across south central South Dakota in response to a weak mid-level wave drifting out of western South Dakota. A slight increase in the low-level jet brought deep-layer shear to 35-40 knots, and MUCAPE around 2000 J/kg provided fuel for storms to strengthen and congeal into a bowing structure which traversed to the east-southeast. The strongest storms produced damaging winds generally from 60 to 80 mph. In the wake of the evening convection, scattered elevated storms developed, which produced a combination of damaging winds and spotty large hail during the very early morning hours of July 30.
