Not sure we are actually seeing the actual cloud head at this time, but
we must be very close,

.... yes difficult isn't it! Always much easier when it's all done and
dusted ;-)
It's got the 'look' of the early stages of such, and looking at the
sequence, the cooling tops are becoming more organised .... interesting
few hours coming up

I don't think it was a cloud head at that time. There was a mass of convection
in the area which as the left exit of the powerful jet approached started to
become more organised due to mass ascent inucing a rotation as the PV max
interacted with the cloud area. At that time I could see a developing wave and
mass ascent taking place on the cold side of said wave. Buckling of the imagery
and more cloud top cooling will be a better sign of rapid deepening beginning.

As I suspected looking at those blobs on that front:

This one has similarities to October 1987

as at 21Z looks more like an instant occlusion than anything, with
cloud filling in between the comma and frontal wave. We're not gonna
see a cloud head ...........

Beat me to it ! I was about to post a similar thing based on what I'd
seen earlier today. Quite interesting, but if I'd looked at the 2300
image in isolation, I'd have said it was a cloud head. There's almost a
feature in advance (to the north) of the cold air development that
looks cloud-head esque.

Will be interesting to see if any low of note forms overnight. I'll
tempt fate here and now by saying it'll be a damp squib. Any inland
70mph gusts are now my fault !
