Default Interesting N.Sea cloud dispersion near East coast

The sat. image below received at Plymouth Uni shows North Sea cloud
evaporating completely near NE England coast, and silhouetting the
East Anglian coast in partial dispersion.
Is this only a sea surface temperature phenomenon or could the onshore
winds be gradually affected by the changing synoptics which are
bringing southerlies and southwestelies aloft?

Yes Len, an interesting effect. Looking at the visible channel replay from
RSS (5 minute scans), it looks very much like a sea breeze circulation
developed, but possibly enhanced during the late afternoon by an increasing
SW'ly component at cloud level. It is an interesting example where the sub
Sc level air is unstable enough to allow convection inland to develop from
the diffuse radiational heating getting through the Sc layer. Individual Sc
elements can be seen on the imagery accelerating away from the coast over
the sea and dispersing there, while inland the Sc tops are moving slowly,
mostly, I suspect, spreading out from the convection below. The perfect fit
between the shape of the coast of E Anglia and the edge of the dispersing Sc
attests to the sea-breeze subsidence in action.

Thanks Bernard.
Having 5 min scans was handy for giving an explanation.
It was hard to see at first a sea breeze circulation setup with so
must cloud over the land but as you correctly point out,
it was not so thick as to prevent some solar warming at the surface.
