I'm pretty sure a few French weather forums are likewise buzzing tonight...

The party certainly has begun with cells popping up over France, these will start becoming more organised as the night goes along converging into several MCS's moving in a NNE direction towards the UK. Hopefully as these start to move North, moisture can be ejected into our green Pasteur and some home grown storms can appear.

no missed it what did it show??

 

 

Overnight tonight the SE have 'imported showers which could give some flashes' and Thursday 'heavy, even maybe torrential downpours with thunder'

 

The PPN forecast actually shows a massive group of storms appear from nowhere around 3am in the East Channel.

Which forecast? This one?

Or is there a more recent one. That one sounded pretty good to me I have to say. There may yet be hope. :-) :-)

Latest BBC forecast anticipates a wave of storms sweeping north tomorrow night extending North through Thursday.

As ever, treat forecasts with caution as this is a very complex setup!!

Also, as others have mentioned and I have learnt, these storms are very elevated so the channel shouldn't kill them off as fast as it normally does because the surface shouldn't have as much of an influence to them.

Nope not that one! John Hammond did it. I can't find a link yet. Time will tell. 

 

Thursday looks good for further north as well! Whether the precipitation will still be electrified by the time it hits Merseyside I don't know.

OK, thanks, and yes, I really hope so, maybe the elevated nature of it will help, and it might help it to reach you as well as it shouldn't be affected too much by the cold Liverpool bay waters. Lets hope we get a nice surprise anyway. :-)
