I'll defer to those with better knowledge, but it has shown no supercellular properties that I could see.

In all honesty, that storm is travelling towards London. 

Yep anywhere between the square, Reading- Bournemouth-Brighton-London...

That storm ain't going to survive the Channel crossing, in my books, as I would imagine its well rooted into the boundary layer now. I've highlighted the area I'm watching most in red. I may be wrong however, but that's how I see it...

 

However they are elevated, so I dont see why the surface (the channel) should affect them that much?

Hoping the warm air its riding feeds it enough energy to survive the crossing

It would appear that more storms are developing behind the line headed towards the Channel and these are now becoming electrified. Bodes well for overnight, so long as there is not too much murk about in the morning. Sadly, we have all seen this in the past but, ever the optimist.......

That's where I'm stuck, I can't decide whether its likely that its well routed in to the lower atmosphere yet or not.

Another storm seems to be developing just south of Rennes.

Hmmmm there seems to be a downdraft from the storms to the north, which then behind displaces the air and forces it upwards (updraft) forming these storms?

Funny how exactly the same thing happened on this date last year. Portsmouth and IOW being slammed by a small import ! And I witnessed it !

I guess we will soon see. Live lightning site is great in this regard  :good:

There's definitely three distinct storms in Northern France going on at the moment. The most intense looks like the one around the Fougeres area and heading NE.

Gonna be a good while until anything gets to the UK & with no signs of anything firing further North, I'll take my leave. Hope things improve for you all-nighters!

I think if there had been a supercell, the boys at Keraunos would have mentioned it - just clusters of single cells from what I read.

Thanks@all for the warm welcome here :)

The outflow of the initial Nantes supercells seems to have created a very promising outflow boundary along which new cells are being triggered off northwards. This is basically like a mini cold front going north and is clearly visible on SAT24 Infrared. The boundary is the curved top of the white now mushroom shaped ex Nantes storms.(If someone from the Forum could post a grab off the SAT24 site would be much appreciated, have to get into downloading pics first)  

Shows how much instability is present, and also can speed up matters: If further cold outflow from the french storms makes it to the south coast and shifts under the pre frontal unstable airmass in the UK things may become interesting soon because we wont have to wait for the actual storms to arrive across the channel.
