For about 15 minutes, this section of a line of storms produced a wickedly brilliant barrage of forked, cloud-to-ground strikes ahead of the main precipitation area, as it interacted with a fresh outflow boundary and evolved into an embedded supercell. The step-leader branch that didn’t quite make it to the ground (at left) was lit nicely by electricity that had surged up through the branch that did, at right. Both branches met unseen, just above cloud base.
