On a more serious note, I recall a night in August 1975 when the lightning from very distant storms was being reflected off cirrus clouds; and, couple of years back, I could see lightning from a monster storm in Milton Keynes!
Good luck for the weekend!
It's amazing how far away you can see lightning in the right conditions. I've seen lightning from a storm in Sussex from East Dorset before. Forks too! (from the anvil).
I've also heard thunder from many miles further away than popular thinking says possible. Like 100 miles! It was late evening last year - incredibly still under plume conditions. Very, very deep rumbles.

Towering Cumulus north of Bournemouth. Interesting.

I wonder whether the development of a low pressure cell along the line of the front along the channel coast (as can be seen on the fax charts) could re-vitalise the front to keep the moisture levels going once the temperatures/dewpoints/DAM/WBFL have become more conducive to snowfall?
Here's an example of the biggest snow event here in recent decades when a LP (shown over the channel) developed in a decaying front coming down from the north. Temperatures/dewpoints/DAM/WBFL had all been favourable - the issue up to that point was lack of precipitation, so granted not the same scenario, but the LP 'made' the event.
Remember that - the Met Office had Bournemouth on a Red Warning for Snow but the LP moved just too far east before it stalled and we totally missed out, whilst the A3 corridor got absolutely pasted.
I'd be interested to understand what made the LP stall and reinvigorate if anybody can explain.

Nope. it'll bypass Dijon - just watch! The storms always go crazy over the Morvan and then zip north, I've stayed up half the night over there only to get nothing but distant flashes...
I've honestly never seen a strike rate like this - it's incredible to watch (even just on Blitzortung.org)!!

Still haven't had a good thunderstorm since September 2014 here, very depressing. Still waiting for lightning but looks like general rain. Ah well, we all knew tonight would be a damp squib.
I thought that storm that tracked due north just east of Exeter earlier today might have been a direct hit for you?

Wowser
Microburst.

Edit to add: In the time it took to post it has gone beserk!!
Haha - yeah, loads of people caught out and taking an early bath!

This one may well be worth a shifty in half an hour or so.
Prefer this one of Amsterdam:

You can choose where to point the camera.

Aw I can't watch it on my phone :'(
The best bit was just before the storm arrived - a light grey skyline being invaded by menacing black cloud. Once the storm hit there was tons lof intra-cloud lightning, gusty wind and very heavy rain.

It's surprising how far you can hear thunder at least over the sea, Most places I look say 10-12 miles max but I have definitely heard distant rumbles from much further on several occasions, up to at least 30-40 miles. I even heard something that sounded like very distant thunder earlier though even I think that may be too far.
It seems to me the storms in west Brittany are moving NNW and the storms SE of Jersey are moving NNE.. lol
Edit: went outside for a couple mins and saw a bright meteor through the high cloud to the SE, for a split second I almost thought it was lightning.
I'm in Bournemouth and have been able to see flashes from my garden for the last 45 mins or so. Heard a couple of rumbles of thunder too and the lightning was only just north of the Cherbourg penisular. Funny you should say that as last month I was sure I could hear thunder late one evening from storms in the west London area but as you say, all sources suggest 10-12 miles max.
EDIT: PLUS.....say the most amazing shooting star with a trail that stayed in the sky (like a contrail) for a full 10 seconds!

Seems I may have lucked out. Weak storm skirting with the south of the island this morning (I'm in the north) and a nice looking storm just north of Ibiza.
Nothing doing here, just a bit grim.
EDIT: that storm north of Ibiza appears to have developed supercellular characteristics. Very rapid development and a definate hook echo now showing on the radar return.

I don't have a good feel about this. I suspect I've seen all I'm going to see tonight. Ho hum, we'll see.
Night.

So, I've caught a few flashes of lightning over Majorca this evening - nothing too much and not too close, but some nice low pitched rolling thunder. Seems to have died away as quickly as it started.
Seems like the main event, if there is to be one, may be a few hours off yet. May try getting some kip and hoping I'm woken up if it properly kicks off. (Have to balance my love of thunderstorms with keeping my wife onside! She wouldn't be best pleased if I do an all nighter and am too tired to be of much use looking after the kids tomorrow...)
Here's hoping we all get woken up on the middle of the night!!!

As ESTOFEX say "the stage is set"! Do take some photos if you can, the viewing potential especially on an island can be unbelievable. Stay safe though, it's a bit of a scary setup down there and things could get pretty wild - it makes you remember that the Mediterranean is not just flat calm blue water and idyllic sunny beaches! Enjoy...
EDIT: Look at lightningmaps - almost the whole of Spain is being engulfed by storms!
I'll try to, assuming it's not a bust! It's been sooo humid here. Ac Cas the last couple of evenings but just strong sunshine all day today. Very windy though and high cloud moving in from the South now.
We've changed rooms from a SW facing balcony to a NW facing balcony, so I may have to venture out to get a good view. We'll see what happens!
-
I'm in Majorca at the moment and literally wetting myself with excitement - Level 2 issued by Estofex for tonight.
-
The tanks were firing at Lulworth - I could hear it from my house pretty clearly. I live on a hill and the sound carries straight across the harbour from over on the purbecks. B-BOOOOMMM
Hmm, maybe. I did hear some simple 'booms' early on but these were followed by classic rumbles and I'd be very surprised if these were anything other than thunder. I guess maybe that could have been tank fire echoing though? Do the army tanks fire as late as 11.30pm?

I have definitely heard thunder from way more than 12 miles so it is believable IMO, once I heard it from a storm just west of Okehampton (about 30 miles), and a few other times from storms out in the channel, up to 40/50 miles away from here. Mostly evening or night (except one morning last July), and always from elevated storms (though storms here often are elevated).
I don't know if it was positive CG's or atmospheric conditions conductive to 'bouncing' the sound waves to further distances (have heard of this before), or even bolts extend closer than the radar showed the storms or the lightning detectors plotted them? However it always corresponded to the direction and the timing which lightning was detected (with a delay of a few minutes..), and there isn't much else between me and the sea to cause the sound instead.
I have also only heard the same sound with distant and/or approaching storms.
I do live in the countryside though where it is pretty quiet, wouldn't think I'd be able to do hear or discern it up in Egham.
Also on a different note, when playing back the radar (NW Extra) you can see the last cell rotating as it crosses and exits East Anglia! Also the cell and its corresponding lightning strikes on lightning maps appear to take a slightly more easterly course than the rest (possible supercell?)
Thanks for the reply, interesting stuff. Now that you mention it, I have also heard thunder from way out in the Channel - as you say, always late in the evening when there is little background noise.
Makes sense that the audible thunder may have been generated by powerful positive CG strikes.
-
no it's not...it's either developing cells in the channel not showing on the radar or it's tank exercises on Salisbury plain, larkhill are firing tonight so that's a possible explanation
I'm still perplexed by this. There is absolutely no question that it was thunder I could hear late yesterday evening. I am 100% certain of that.
I've since checked the infra-red satellite imagery for the time and there was no cloud anywhere near us that could have produced lightning (in fact we were enjoying an exceptionally clear sky). I'm very aware that thunder 'shouldn't' be able to travel more than approx. 12 miles, but I have no other explanation.
-
Why are people not hearing thunder with elevated lightning? Surely it can't be that high? You can hear thunder from lightning say 6 maybe more miles away, is the lightning higher up than 6 miles??
Not kidding - I can STILL hear thunder here in Bournemouth! Maybe 'cos the skies are clear and still, thunder from elevated strikes carries a long, long way?
-
Been sat in my garden the last 30 mins. Lovely and warm - very, very surprised to hear lots of loud booming thunder. Can sound really travel that far or is something going off closer to home that neither the radar nor lightning detectors are picking up?

I wouldn't have believed it if I didn't see it myself.
Just had a rain shower from a blue sky with just a few wispy clouds around! And they were heavy convective type drops, quite mental
Haha - I've experienced that before; weird isn't it?!

Gutted I didn't have the courage of my convictions and go to the clifftop yesterday evening. I was at my son's sports day in Bournemouth yesterday and was surprised by the amount of instability very high up in the atmosphere.
Great pictures by the way Christchurch Storm Nut!

If this doesn't whet the appetite, nothing will!!
Bournemouth 3rd July 2015
Epic storm - the world seems to be ending at its peak!! (I had a front seat view of this from the clifftop, but can't take credit for this excellent video)
