We already had seen two fantastic supercells on this day near South Dakota’s run of US-12: one looming over the highway near Aberdeen and another with rings-of-Saturn striations closer to the Minnesota border. That just wasn’t enough! Even though this young, clearly spinning storm was becoming elevated over rain-cooled air from an earlier gob of storms, its internal dynamics maintained storm-scale rotation long enough to cast the cloud structure into a wonderfully layered form. For a short while longer, this plume of fluid art gracefully twirled across the late-afternoon scene, gently dappled by low-angle sunlight. Meanwhile, a still-newer supercell assumed its position and influence in the northern sky.
