The episode as NWS JAX wrote it up.
An outflow boundary from a large MCS that developed over Georgia pushed into our Georgia zones during the early morning hours. In addition, an upper level short wave trough enhanced convection along the outflow. During the afternoon, the lingering outflow and sea breezes spawned more storms in a moist and unstable airmass over our Georgia zones.
