Fred, I noticed that too...should be be temporally limited due to lack of forcing ahead of it...maybe a couple of discrete cells.Still questions in the modeling with how the Baja area upper low will affect the late week evolution. I think we may have these questions another day or so. I'm starting to get the vibe though that regardless of how Saturday evolves, we need to watch Friday into Friday night with the lead impulse that comes out. There won't be a lot of forcing, but shear will be there over the warm sector, and the thermos will be there... since the warm sector gets into place Thursday night into Friday morning.
