The Wall Cloud Wall
Last Gasp in Twilight
After producing numerous tornadoes in its march from the Red River to central Oklahoma, including the wind-farm and another near OK-19, this supercell finally had spent all its intense ground-based spin. Still, even in the fading twilight and increasingly feeble boundary-layer temperatures, a residual wall cloud continued to hang very low and visibly rotate--albeit very slowly. The supercell was weakening, its internal dynamics producing too little upward motion to help with one more tornadic spinup. Given the profusely tornadic history of this supercell, however, only hindsight can be fully certain of that outcome!
