To answer the title’s question bluntly: No! Nonetheless, those imaginary images came to mind, even in real time, as these otherworldly, supercellular cloud formations shifted quickly northeastward over the remote High Plains countryside south of the Black Hills. Perhaps scenes like this have contributed to the mythos of visiting aliens. Wall clouds usually are far more convective than laminar, yet this one manifest a column of relatively strong lift below ambient cloud base, forced by the low/middle-level mesocyclone in the supercell above. Its downward tilt, scientifically explainable as lower toward moist air emanating from the translucent forward-flank precip area, also conjured a flying saucer angling in for the landing. Meanwhile, the tail cloud under the vault region both demarcated an outflow boundary from storms to the north, and split a northwestern sky gathering ever more golden tone as sunset time approached. This was the third and last “Provo supercell” in a chain, that I observed in just a couple hours.
