Default Perfectly balanced 'arc' of line convection west of Portugal

choose VIS imagery for Europe and you can see (now the sun is illuminating
the cloud tops) a near-perfect arc of line convection with (I think) just
one break. Seems to be coming forward associated with cyclonically-sheared
development associated with the slow-moving/warming-out vortex seen here

The band of activity also seems to be linked to the region of strong
diffluence near the axis of the jet on the southern side of the upper
vortex, also linked to a short-wave trough rotating the vortex.
