Some great in situ convection across France too today. These are my favourite types of storms: develop in place, single cell, last 20 minutes or so.

Scattered showers around Lowestoft area on May 21 from unstable medium/high clouds but rain never reaching the surface, just large virga.

Some chunky MCSs over NE France and Belgium with some strikes now off the Kent coast on cells that are developing along the trough.

Those storms are now going off-grid in terms of energy. Rain makers from here on in I suspect.

Tomorrow looks potentially lively dahn sarf with some good LI and SBCAPE (although as suspected moderated somewhat from the mega-values GFS was showing earlier in the week). Insolation I suspect will be key in how intense some of these storms become with the risk of crudvection hampering the sustained conversion of the available energy, but imports from the continent for the south and south-west are certainly on the cards.

Saturday PM (LI of -7 and circa 2,000 CAPE):

 

Sunday PM - risk slightly further northwest:

 

Monday PM - more widespread risk but concentrated in the SE:

We've just had a couple of thunder showers pass right over us here in Frome, nothing to dramatic apart from one CG which was very close and made one hell of a bang, a real deep punchy boom, very nice but the storms were over and gone very quickly,

Thunderstorm just developed to my east and has now rumbled away to the north east. Some nice pink lightning for a while. Always looks best just after twilight.

We had hardly any rain here, which made for good watching conditions.

Incredible line of storms through the Channel and into the southern counties! The storm in Kent looks particularly active!

Strobing away quite nicely (and safely for now) to my south west, coming from that newly developing cell just moving NW onto Dungeness as I type this.

Very frequent lighting was heading my way, actual fact lightning every few seconds then it just turned off, now there's nothing apart from light rain, seems weird how it stopped so suddenly.

I’m waiting for Brian to wake up as I’m hoping he can confirm that he also had these intense storms in this area overnight 

seemed to go on all night but certainly a few separate ones that bought monsoon rain and some stunning lightning .
