What the National Weather Service wrote

Broadcast media relayed a video of hail falling at a residence near the intersection of Key Road and Hwy 23. Largest stones are estimated to be quarter sized based on the video and the individual who sent the video.

The wider storm

An approaching mid-upper level trough from the TN Valley provided sufficient synoptic forcing across South Carolina for widespread severe pulse convection. Ample low level moisture and steepening lapse rates as the trough neared allowed for strong instability to develop, with very weak deep and low level wind shear. A deep layer of mid-level dry air wrapped around the trough aloft and provided sufficient evaporative cooling aloft for both severe hail production and enhanced downbursts.

Began near Colliers (33.7441, -82.1011).
