On my phone so can't post a grab but that shower near Ludlow has an interesting shape to it. May be just coincidence that it has formed into a comma shape but would be interested to know what it looks like from underneath.

It's started pelting down with rain here, but still no thunder. Just looks like gloomy rain clouds, so much low cloud/mist about today that you wouldn't see any towers. Haven't had a single rumble this year so far...

[Snow Slave]

I have just come across this on my fb feed. By far the best footage I have seen of last night's storm here in South East kent, they had an excellent elevated position at the top of folkestone by the look of it.

Just amazing and beautiful.

Managed to get a few shots at Pevensey last night, although the rain hit and forced me under cover before the lightning came close enough to catch the spectacular crawlers that followed.

What camera was that on couldn't get my canon 750d to work last night

Day 2 Convective Outlook

VALID 06:00 UTC Tue 30 May 2017 - 05:59 UTC Wed 31 May 2017

ISSUED 21:20 UTC Mon 29 May 2017

ISSUED BY: Dan

Disrupting upper trough will migrate eastwards across the British Isles on Tuesday, with a weakening occlusion/cold front at the surface drifting SE-wards. There may be sufficient forcing, given residual moisture near the surface, for some convection to develop along and/or ahead of this front, although large cloud amounts may limit this potential and in either case the true convective depth will likely be too marginal for lightning. As a result, very little lightning is expected, with perhaps more favourable conditions found in E/NE Scotland where a funnel or weak tornado may also be possible.

I'm quite surprised that last nights thunderstorm has been quite often reported both here and elsewhere as a 'Kent Clipper'.

Whilst the main body of the storm appeared to track eastwards through the English Channel it was quite widely observed from locations as far apart as Dorset to the west, the London area to the north and Essex to the east.

Here in St Leonards-on-Sea it produced some of the most spectacular lightning I have witnessed in the Uk for many a year. It first became visible as distant flashes around 10.30pm but within half an hour it was apparent this was going to be something quite special in this neck of the woods. The lightning was almost constant at times, some of it practically overhead and whilst most of the thunder was just a long rumble we had several shotgun blasts that had me running for cover at the time.

All in all I would rate this a 9/10 for a brilliant lightshow and longevity.

Just noticed on the Met Office twitter feed that an 83mph gust was recorded in the Dover Strait during last night's MCS.

Downdraft?

18z Thunderstorm signs again perhaps on Friday?

That moment when you realise your arms are made of jelly. Sorry for the really shaky camera. Tripod mount fell of but I got this....

The lightning observed in Dorset and across many of the western areas were actually small cells embedded within the rain mass - not lightning from the cluster of cells over the channel.

One small cell over Haywards Heath area produced several large crawlers towards the end of the main storm but while this could easily be attributed to the main cluster due to the impressive strikes, it was about 40 miles from where the main activity was, so was definately part of the wider rain mass.

The MCS was most certaintly a clipper.

There is a tiny part of me that was relieved the storm went where it went and had its back turned to the UK.  It was, at one point, destined straight  for London and feared there would be some fires and casualties from the electrical part dragging over the densly populated area. 

I would call it Kent, Sussex, Dorset, Devon clipper *

 

[edit]* I didn't know about the inland cells being separate from the mcs proper as per flash bang's post. I retract my statement

I was just having a look at some of my IP camera's footage, and found this:

  

[Supacell]

I have finally managed to edit my video from the early hours of Monday morning in Essex. As I said yesterday, I was gutted when I saw the MCS from France take a turn and follow the coast of Sussex and Kent. By this time I was already in Essex but could not really travel any further as did not have the petrol to do so, and no money on me to re-fill (note to self, never leave for a chase without bank card again). I was all set to face the disappointment of heading home with nothing to show for my drive out, but as I was sat parked at East Tilbury I noticed closer flashes to the south-west as opposed to the very distant ones I had been seeing occasionally to the south. I am still feeling disappointed that I did not get to be in the stronger storm to my south-east but at least I was able to get some crumbs of comfort. The video below shows some of the storm that passed near to Tilbury.

Now that`s the way to do it......Impressive as ever Supa

Some strong gusts

Nice to see what we missed on
