A long, graceful, gently sinuous shelf cloud rushed outward on rear-flank outflow that could penetrate the boundary layer. That outflow mainly came from the storm in middle background—one of a series of east-northeastward-moving supercells on this day that were undercut by a slow-moving cold front about the time they would mature. Even though I had light north winds at this location—ahead of both the shelf and front—the frontal air here was shallow enough to permit lift above it for the shelf cloud to take such classical arcus shape. Other than this and a couple other similarly fuzzily structured supercells, this chase day was not very noteworthy, except for the fact it landed me six cats. Soon after the photo, I would head to a motel in nearby Munday, where a very hungry and affectionate little cat aggressively befriended me and (remotely) Elke amid sporadic rain and thunder. I brought the cat (Stormie) home the next day, not knowing she had five little seeds growing inside. By late summer, three loving households in Norman had beautiful new kittens thanks to this otherwise unremarkable storm chase, with two for us, plus Stormie.
