Rather frustratingly, these storms appear to passing to my east and are not getting any closer to here (Edinburgh generally doesn't get "interesting" weather after all, so that is to be expected).

There is the odd lightning stroke showing on the detector map and these storms are close enough, such that I should be able to hear any rumbles of thunder which come out of that, or see at least some of the lightning from that in the distance.

Up until now though, I haven't noticed anything in that regard.

Everything is looking very dark and threatening to my east and those cumulonimbus clouds look very majestic as they tower up into the sky.

However, the Sun still refuses to stop shining and it is still very hot and sticky here as a result.

We don't have underground stations that can flood and we are very flat..

Near to me after Sundays storm..

Storm's just moving in now with at least 10 flashes in around 2 minutes. Certainly seem more active than friday night's attempt. However the core might just move southeast of us just clipping as it moves inland towards Hayling.

This is a violent storm!! Saw rotation in clouds just before its struck so probably supercell.. insane rainfall and winds probably around 50 mph ducking mental

Some more information on the storms in East Anglia/London on Sunday

Dan Holley on Twitter: "@RoostWeather just been on the phone to a retired farmer in Brettenham, he used to be a voluntary observer for the Environment Agency until about 5 years ago but still has a working official rain gauge on his property. He recorded 181.3mm in 1hour 40mins (16:40-18:20)" 

Not sure if link will work, is all on above Twitter feed. Includes an 100mm + total in NE London. 

 

 

Net weather lighting detector has shown barely any lighting but this has just given one of the most electrical storm's in year's here with most overhead or very close.

Crude estimates but we're going on for 3 inches of rain... comfortably 60mm.

Garden flooded.. most likely flooding around town but will here more in during day. I think because of the time of night most won't be affected, but still the noise of at one point almost constant thunder a lot will have been woken.

I think those lightning detectors only tend to pick up CG lightning, rather than CC and IC lightning.

The Met Office forecast has a couple of thunder symbols for this evening around here. Not that it really means much though, so I'll wait and see...

Must be because at it's peak there was at least 12 -14 flashes a minute. Lot's beautiful sheet lightning, and IC, but i only observed a few fork lightning.

Thunderstorm activity building near Lincoln but at some distance from us for now.

You are right, and they only represent about 25% to 50% of flash producers in any one storm.

I'll echo Pitcure's comments that last night's "direct hit" over Portsmouth and Hayling Island in Hampshire was quite something. Properly tropical. I don't think I've ever witnessed such an intense combination of wind, rain and lightning. Local weather station Chimet showed the squally wind picking up to around 50kts from nothing within an hour?! And this morning it's calm again. Quite surreal.

I sometimes noticed that lightning detectors (LDs) don't always pick up lightning. There was a thundersnow event in Lowestoft on night of 17/18 Jan 2013 that wasn't picked up by LDs.

There was also numerous volcanic lightning in the paroxysm of Etna on 4 Dec 2015, bu there are no record of it detected on LighningMaps.org.

This is why detection of extraterrestrial lightning by radio on Saturn & Venus has been fought with difficulties with false negatives, causing controversies (though Saturn lightning was finally confirmed in 2007).

Very suddenly active over North wales, especially over towards wrexham

Yes, just noticed that , hopefully a sign of things to come over a wider area a bit later. 

Quiet here, hazy sunshine and just under 20c.

all to play for just about anywhere today - in England at least - alarm speed once again that showers can come out of nowhere. And again it is slow moving day wind wise.

Indeed. It will beinteresting to see how much rain was picked up at Thorney should it end up being the regional wet spot, however the core of the intense rain was over Portsmouth, west Hayling and the Northeast IOW. 

Good work - I was unaware of this until I saw some lightning shots from Jamie on the IOW.
