I assume for you that would be this lot 

I saw and heard that from here.

Seen three stunning CGs into the sea here in the last hour and very deep thunder from them.

Can see lots of virga to the northeast of here now with the orange sunrise sky peaking through.

Well that slowed right down in its March East, it went right across Cornwall and most of Devon in about an hour, was expecting it closer to here, now, but it looks in more or less the same place as when I went to sleep lol.

Well just as I predicted not ruling out SW to have some structure. Good little chase despite the lack of lightning however some great CG. Anyway good luck to you guys chasing on the East.

Estofex have the south east of England highlighted for storms today.  Storms later coming from north east France and Belgium may effect the Kent coast.  Still all good to look out for. Sorry, but don't know how to post the link on my tablet. Enjoy your sky and radar watching.  All quiet up north.

Chuffed to see that some areas got some thunder and lightning action last night

Seems that I will not be seeing anything here this morning as the area of instability seems to be just to my east. Fields of Ac, and increasingly AcCas and jellyfish clouds have been steadily increasing over E London, N Kent and Essex in the past hour or so. 

Just a question now of whether this zone of interest will fire or not.

[Paul Sherman]

Yep up at 5am to a clear sky.

Now rapid destabalisation taking place with AltCas everywhere and skie filled in to 7/8 with the approach of the Trough

Next 2-3 hours will show wether Storm will form or not

THUNDERSTORM OUTLOOK - THU 21 MAY 2020

Valid: Thursday 21 May 00z - Friday 22 May 00z

Scattered thunderstorms are expected to form in SE/E England during Thursday morning and early afternoon. 600-1,400j/kg MUCAPE will be present on Thursday morning and will support these heavy thundery showers. However, an approaching trough from the west will determine how much thundery activity we get. If the trough swings in faster than expected, then the risk of storms developing is very low. A delay in the trough could mean that the thundery activity will be a bit more widespread. If heavy showers/thunderstorms do form over SE/East Anglia then by the early afternoon they might drift out into the north sea. This could yield quite a few hundred j/kg SBCAPE although the chance of any surface based storms is unlikely.

The skies are destabilising here!

[Harry]

Might have been slightly premature in my conclusion of being out of any zone of interest. Fresh wave of moisture/instability now arriving from the W/SW. Jealous of some increasingly meaty looking AcCas though off to my east - possibly Southend way maybe??

First picS looking W/SW while the third pic is looking towards Essex

Lovely looking cloudscapes here. 

[<<Ryan>>]

Nice to see some instability, though it seems any storms will now be to my East should any form at all

 

[Mitch the motorbike storm]

I'm not expert of convection but is this a good sign?, bit of huge development just now

[Thunder and Lightning]

You can really see the dry air associated with the trough on the overlay of water vapour imagery. I don't think I got the position of the trough quite right so please correct me. The 0z Herstmonceux sounding doesn't show any instability, but it was in the very early morning and it does show some quite dry air aloft so interesting to see that. Also worth noting that the wind profiles are looking quite favourable for storms, with a nice veer with some OK directional shear. So overall mixed feelings about today but for some reason I'm feeling lucky 

[Thunder and Lightning]

Lots of AcCas with a very warm feel in the air. My skies are still clear and it is already 17.6c!

[Weather-history]

Surprised to have caught a couple of distant lightning flashes over the Irish Sea around 3.25am this morning. Can see the flashes to the right of the bungalow

 

[Mitch the motorbike storm]

Storm heading towards me now?

[WxHerts]

A few towers rapidly going up to my SE now, clear skies to my west and sun just risen above accas..come onnnn

I don't know if the camera can pick this up but there are big fluffy clouds in the distance 

[Harry]

This is (as I predicted the other day) literally building over my house and I’m staring straight up the rump! 

Whiff of petrichor as I stepped outside too.

Some very nice structures to the London area from Essex. Apparently anything this morning will have Little to no precipitation because of the moisture profiles. Classic electrical storm.

 

havering area looking SW

[Justin1705]

View to the E/ SE from havering. Looks as if it’s forming overhead now. As not much movement at all

[Eagle Eye]

looking at the met Office i should have lightning nearby from 1pm to 4pm although apart from 1pm to 2 pm very distant

[PurpleLED]

is this the trough thats been close to me for the last hour or so?

 

whatever the feature is the cloudscapes are lovely and make for some great low quality phone photolapses lol, looks like a lot of cumulus is starting to build up from what i can tell so good luck to anyone downwind.
