Believe it nor not, this somehow still was a cumulonimbus cloud, barely attached to higher-level anvil material off the screen at right. It had been a small supercell, but got increasingly tilted and sheared over, until the narrowness of the updraft and its internal rotation no longer could stand whole in the face of strong shear, and especially, the dry entrainment from surrounding air, to which small storms are more prone. Ever since my earliest chases, I’ve informally referred to dying supercells of this form as “chicken neck” in structure, and it’s not hard to see why. The radar unit at distant lower right is the KPUX “Pueblo” WSR-88D, located well east of Pueblo on the ranch lands of the High Plains. Even though this stage largely was in the radar’s “cone of silence”, it wasn’t missing anything important.
