Out of sheer morbid curiosity, and I'm fairly sure I know the answer, but has the UKMO ever issued a tornado warning for anywhere in the UK?


No. Probably?

Confused, is this storm approaching the SE suppose to be the main system thought to be distributing storms across more western/central areas early tomorow morning?

There is dark cloud with lightning to the east of me. I'm halfway between Guildford and Dorking in Surrey, so a lot further inland than other reports. I don't know how far away it is to the east, though. Can't hear any thunder, and even the dog can't hear it (she usually starts going loco when she hears it, which is well before we are able to!).

Sky has cleared here over the last hour with all the action happening further east. Cannot complain after last nights fantastic lightning display! Temp still around 21c.


Still expecting storms later tonight with developments over Western France looking interesting

Do we have anyone in Eastbourne/Hastings area? Would be nice to know what's actually occurring in the real world.

overall push of the MCS is ssw/nne  - currently the western extent on a line to push through central london. the next batch of storms now pushing  nne out of bordeaux seem to be on a similar track to this initial MCS. all forecasts had the flow of storms generally s/n with a trend to be se/nw. i guess we have to wait and see if they begin to drift onto a more northerly setting.

It's not like the US plain-spawned efforts where cold and hot air masses collide over the Rockies. A unique world set up that turns tornado chances from unlikely to very likely in certain circumstances regularly through any given year there.

Looks to me that these storms are tracking more NNE at the moment not Northerly and may hit mainly the eastern half of the country.

Got hail falling here now. Plenty of lightning too.

"The most intense storms will likely occur in across far NW France in vicinity of a prexisting convergence zone (near a line from just south of Rouen to Lille). Given the strong CAPE, very large hail will be possible. The storms may well develop into a bow-echo capable of producing gusts > 32 m/s. A threat of tornadoes will exist if a storm can interact directly with the sea-breeze front.

I am currently in Arras which is essentially exactly on the "line" mentioned in the above post from ESTOFEX. It really is very warm and humid (still just below 30°C currently at nearly 10pm) and although now cloudy there is not much sign of storm activity...yet.

Rumbling now in Medway, hopefully the Rochester Castle Garden proms won't be affected to badly as they're being held in a more elevated position and outside. UB40 are playing.

Suddenly very dark now!
