The current Severe Weather Warning predicts that the thunderstorms will
develop over North Wales late this afternoon and will become widespread
over Norther England this evening. The present activity is much further
south than that with sferics showing an increasing amount of thundery
activity over Devon. There's nothing happening over North Wales yet.

Looks like the forecast was a couple of hours out. There's some kicking off in North Wales in the past hour or so.

Here in Cranleigh, I heard quite a heavy shower outside around 20:30
BST, but it doesn't seem to have lasted long..

A PWS in Bitterne reports 68mm - peaking 223 mm/h and almost all
during that late evening thunderstorm, with one at Midanbury 53mm and
both are supported by the rainfal radar accumulated precipitation
estimates.

Only 7 mm here in W Fareham but boy was that a spectacular horizon to
horizon lightning spectacular, lasting about 45 minutes with mostly
c-c flashes every second or two at times. It may only be April but I
haven't observed a 'summer' thunderstorm like that for donkeys years -
brilliant!

Here at the plebby end of Surrey there has been no lightning or thunder and merely a one-minute spell of moderate rain.
On the 0030 Radio 4 forecast Matt Taylor said there was thunder "to the south-east of England". I *think* this means there was thunder in SE England but their lingo is often absurdly contorted. It seems "in" is a proscribed word. Too ordinary, too prosaic. Linguistics apart, the statement itself was wrong. Blitzortung showed that the thunder over SE England had died out at least half an hour before he made the statement. There is some rather weak renewed activity over northern France. In the UK the main activity now (0105 UT) is over Hants/Wilts.
In a different context Matt Taylor mention Bude, which he said was in Devon. Maybe they've moved the border - or maybe the town. Who knows?
