Light rain down here since about 18Z from quite threatening looking skies on
the edge of the frontal band; not expecting too much from it though.
Tomorrow looks more interesting as contour heights continue to fall and a
further lobe of upper forcing moves up from the SW.

Any convective development perhaps further enhanced by localised
convergence.
