Well that fog got Retford fast lol. Fog indicates stable air as well which kills storms. 

Not always true, a few years ago I was watching a French light show through fog, and could even hear the distant rumbles, and it got closer and closer, till it hit. The fog didn't lift before it got here.

They don’t like the channel

In La Have those thunderstorms look like they're going towards Southampton tonight I was hoping they do go that way see lightning from my bedroom window in Warminster in Wiltshire

Can anyone see that French storm from the Kent coast?

Yes

 

[Allezwasps.]

Could be more fun and games if they make it across later ...

As impressive as the radar is for northern France the meto forecast radar ain't so bullish. Part of the problem is that the storms are too slow moving. They are forecast to make it into the channel and then fizzle out and cross the southern UK tomorrow as a fragmented rain band.

To be fair the meto forecast radar was very good for Saturday and Today (were it only ever forecast small clusters of storms on the coast down here) but it did underestimate the storms over Birmingham quite a lot yesterday.

Meteociel Arome model shows the storms moving towards the south coast while losing intensity - may be some night time lightning over the channel I guess. First strike in the channel just now.

       

Better then nothing lol.

I saw 0.33 of lightning in southampton from a spark after turning my tv screen on, does that count?

I know, there is some strange cases. Like when I used to watch the discovery TV show storm chasers there was an episode where fog came out of no where while a supercell with a tornado on the ground in the same area. The tornado just appeared like a ghost. It was really eerie.

Sorry it only counts if its 0.99 of a strike.

I think it’s probably going to be a case of the dreaded thundery rain for the French mcs I.e just a wet mess by the time it reaches here.

[chapmanslade]

Fog means no surface based convection but higher level convection can happen independent of ground conditions such as happened on Saturday night when it was very misty here

Never heard of that term before. Can you explain it to me please?

It cools the surrounding air rapidly to produce water vapour.

Thank you, I guess that's a good sign since that would indicate a good updraft.

I’ve seen it in a few vids on YouTube. Amazing - it travels so far and so fast.

I wonder what it’s like being near the strike zone? Image a lovely day walking along and out of nowhere a huge bolt of electricity

The cold hail land on the hot surfaces and causes fog as it melts.
