A formerly robust, somewhat high-based supercell started undercutting its own updraft with outflow, as such storms often do, to their permanent detriment. The former wall-cloud area at lower middle-right had become more of a shelf cloud, with likely just a narrow ribbon of surface-based inflow air still ingested into the updraft rearward of the visible shelf. Still, somehow, the storm fought back the convective reaper for another hour and a half as it churned steadily south-southeastward past a wildflower-festooned valley and into richer moisture and assumed a spectacular, striated structure.
