The event in January comes to mind. That QLCS was very prolific, produced several long-tracked tornadoes (and several EF2s), and led to several deaths despite instability quite a bit lower than this. There is also a substantial after dark component to this, which extends to the East Coast.
I don't really know what you mean by "what I'm describing". If you're implying I'm saying the doom of the SE is coming on Sunday, that's definitely not it. A high end outbreak is not locked in, but saying brief, weak tornadoes are mostly going to happen with this level of shear and low level moisture regardless of storm mode is also a bit on the extreme side.
