If it's any help Martin at 1100 local this morning the Sc cloud base
was at circa 480m asl looking west (just covering the Hameldown
ridge) and it was drizzling very slightly. Ties in I think with the
inversion higher up. Sc elements slooked very thin with blue sky
visible at times.

.... thanks Will - yes I thought of you when I looked at the imagery -
tramping about the Moor :-)

The mechanics involved must have been quite interesting; I only have
access to low-res imagery, so couldn't accurately pinpoint the
'origin' of the divergence seen on the course-res imagery, but it was
quite dramatic; it looked for all the world as if Dartmoor was
steaming *westward* through a bank of Sc leaving a clear wake. The
mesoscale (even microscale) circulations must have been quite
interesting. Had a look through 'Images in Weather Forecasting' but
couldn't find anything similar.
