What happened

The episode as NWS CHS wrote it up.

Deep tropical moisture was present over South Carolina as an area of low pressure remained west of the county warning area with a weak surface front extending east along the Savannah River. Precipitable water values approached 2.5 inches as tropical moisture continued to advect over the region from the south during the late morning into early afternoon hours. As an early afternoon sea breeze developed, high precipitable water values contributed to several showers and thunderstorms that produced heavy rainfall.
