At the tail end of a squall line, an anchoring supercell that merged in with the line survived for a reasonably long time…until I showed up. Forthwith, the storms up the line shot out a belt of outflow, topped by a classic shelf cloud. The outflow undercut the supercell, and the entire line got messy for about an hour before backbuilding. We often see “Tail-End Charlie” storms attached to squall lines meet their demise as discrete storms this way, while a minority survive that can move hard enough to the right to stay ahead of the outflow produced by the rest of the line.
