A supercell that formed in Montana—just north of an outflow-reinforced warm front—continued to cloak itself behind a deck of warm-advection clouds, including intermittent areas of asperatus, spitting occasional CG lightning, while churning southeastward across the northeastern corner of Wyoming. Take out the northern Plains landscape, and swap in one with more, taller trees, and this could be a supercell view from a rare open spot in southern Ohio, Tennessee or Alabama. The warm front eventually would cross ahead of the supercell’s path, shortly before the storm blasted Belle Fourche, SD, then revealed spectacular low-level structure heretofore either hidden or not present. As the highway-paralleling supercell was fast-moving, a nontrivial measure of patience was needed to stay well ahead, and not let it get too close and risk being overtaken, which almost happened amid the stoplights and wailing sirens of Belle Fourche anyway!
