Are the high grey/white clouds that seem to be currently plagueing the
whole of the UK (with perhaps the exception of parts of the SW and North
Norfolk, and Scotland) a mixture of cirrostratus and altocumulus, I'm
never very good with these amorphous skies? Either way the Met Office
forecast it well on Sunday's Countryfile forecast.

Your description doesn't fit the sky we have here in Wokingham Dave. We have
a complete cover of stratocumulus at about 4500 ft (1.4 km), not by any
means a high cloud layer.
Vertically pointing radar and lidar images in real time can be seen at:
http://www.met.rdg.ac.uk/radar/realtime/pbl.html
and you may find these instructive.
However, you do not state where you are observing, and it may be different
where you are. It is always of use if the location is given in the post.

Hi Bernard, thanks for your help. Cloud base has dropped considerably
here now with more clearly defined edges to the grey clouds which I
would also say were strato cumulus. Earlier it was that higher milky
grey amorphous high level stuff with a few ,I guess stratocumulus
lurking below.If you look at the UKMO vis satellite for 0800 and 1200
for the South of England the difference is quite evident unless it is an
artifact caused by the height of the sun.
