Drone and ground-level views and timelapses of a tornado-warned supercell thunderstorm moves over South County St. Louis (Mehlville/Oakville) and crosses the Mississippi River at the J.B. Bridge. A rain-wrapped tornado moves just south of the interstate and is intercepted near Columbia, Illinois. A power flash was visible north of the storm's mesocyclone. Copyright Dan Robinson
