What happened

The episode as NWS GSP wrote it up.

Thunderstorms raced across the Upstate shortly after sunrise just ahead of a strong cold front. One became severe in Oconee county and downed a few trees - one on a house. The same system produced another severe thunderstorm in York county in the early afternoon. This storm produced straight-line winds that downed trees and power lines on the the northeast side of Rock Hill. One tree fell on a car and briefly trapped its occupants. Large hail of unknown size and power outages were also reported in the same area.
