A very unstable looking sky from dawn to around 07Z, whence the
high-base CU (I did think AC, but looking at the ascent below), not
sure
I could justify AC), rapidly dispersed.

Hi Martin,

It looks ominous on the latest visible imagery -
http://www.west-cheshire.ac.uk/weather/visible.htm

MetO F215 has Ac from 8000/20000 but only isolated in the S (more N.
France) and not really in your area. Maybe some convergence along the
SW
peninsula may push things later on, it's what the 15Z F215 is going
for
with a risk of a TS.

.... whether connected with my early morning observation I'm not sure,
but we've just had (from 1715 to 1820Z) some very useful rain ....
1.3mm, with a 'moderate' burst near to the beginning of the event. The
sky looked very 'threatening' (Beaufort letter = 'u'), and it was so
dark for an hour before the rain set in that the local street lamp came
on. Reminded me a bit of the scene from the 'Darling Buds of May' ....
"Perfick".

Martin.
