An outflow-dominant supercell began to lose its rotational characteristics and surf that outflow northeastward across the pocket of unstable air in which the storm formed. Since we stood to its northeast, that meant the leading edge of the outflow was directed right at is, offering a spectacular, multilayered shelf-and-chamber cloud stack from the western sky (shown here) to the southern. The cloud extension at right had been a low-level tail cloud, by this time overtaken and undercut by the gust front’s surge and shelf cloud.
