Strange Supercell Sky
One in a series of mostly weak, poorly structured supercells embedded in a convective line, this storm sported a wild, laminar, somewhat chevron-shaped cloud deck above the main convective updraft area. The odd cloud form reminded me loosely of a storm I had seen near the Texas Caprock the year before that looked like a winged alien spacecraft. I was fortunate to catch one of the storm’s numerous flickers of “vault” lightning during this near-peak level of its organization, before the cell became more outflow-dominant to my north. The next supercell’s updraft base and wall cloud can be seen through the haze to the distant southwest, at left rear, and I would have to jump east several miles to stay out of its direct path for good observation. I traveled back and forth along SD-34 for nearly three hours, picking off one after another of these supercells as they rolled up the belt from an anchoring genesis area southwest of Kennebec.
