The radar
seems to suggest development of an occluding frontal system with a
"tail" on the rain band.

.... yes, it's got that sort of look about it hasn't it - the
short-wave trough coupling the humidity plume being the mechanism for
widespread ascent I should think. We're just getting some residual
RADZ here now (1045Z), then I assume conditions will improve as the
upper trough edges north.

Glad I've not got to advise Wombleydom on whether the roof should be
closed or not :-)
