Two spectacular supercells wandered eastward to our north on this amazing night—the first a more well-known storm for its unique breaking-wave shape, the second for its prodigious production of middle–upper-level lightning. This flash looks downright drunk! It remains one of the most contorted and erratic lightning channels that I’ve seen or photographed. Were just the visible part straightened out, the path would number many linear miles through cloud-free air.
