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


.... using this site:-

http://www.sat24.com/

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 ...
