Sorry that this is a bit belated, as usual at the moment, I'm running behind in life!
Some interesting radar returns over in northern France showing a really good sized thunder storm, along with a storm north of London at the moment.
I think they may follow met ofice warning area quite well, though I might put the storms a bit more northerly than they show, affecting Essex and Cambridgshire.
Storms also seem to be starting to form in the Welsh borders area and perhaps in the top end of Surrey, hard to see what is happening with them.
