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 -

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.
