I’m wondering if that central band of cloud stretching up from France directly across CS England will kick off once the front out west moves in and erodes the cap

It's akin to a weak squall line moving directly north. 

Precipitation inbound, just south of Sheffield here.

You wait a lifetime for a funnel cloud and then two come at once!

A few from last night, just South of Salisbury. Mostly intracloud stuff, but an impressive light show none the less.  

Well that was a pretty awesome night. Although I cant help but feel slightly disappointed for not getting any SLR shots. And now I'm left wanting more and more ?. Anyway a very impressive light show w

Wow that sucks for north midlands, north and north west england, I do hope it's wrong! About 75% of forcasts/maps go for the areas I just mentioned at highest risk of severe storms.

Just a question; we have moisture moving up through the midlands from the South, and we also have all the conducive conditions in place .. surely that will spark storms right here?

Very heavy rain here now after some small hail for about 30 seconds. Lovely rolling thunder and saw 3 CG strikes very clearly when I was still outside standing in the spotty rain.

 Not a bad storm that. Mostly ic strikes with a few CGs at times but not many. Biggest thing was the torrential rain. Stopped now sun is coming out and it’s getting hot again. Still think there is time for more.

Netwx-SR a bit more keen, but we'll see - tricky day to call.

Might be the case where it is the cold front that is more active than the troughs ( I believe the areas of showers / storm across the UK now are from the trough(s) and the area of rain in the SW is the front ) 20190725.1328.PPVA89.png  20190725.1027.PPVE89.png still plenty of time and possibly some more night time action up here.

You would think so, but your guess is as good as mine mate.  These situations always come down to nowcasting, fingers crossed!

Satellite and radar indicate that isolated storms are initiating over Normandy, the Massif Central and the Jura. They develop in an environment with 500-1500 J/kg CAPE and weak vertical wind shear. Additional storms will likely form in the next hours. Given the high cloud bases, they will bear a risk of severe wind gusts associated with microbursts. In addition, some marginally large hail may occur. In the west and northwest of the area where deep-layer shear is stronger, well-organized multicells are possible that could also produce larger hail, up to 5 cm in diameter.

Satellite imagery shows deep convection developing near Aachen. Additional isolated high-based storms are forecast to develop across the indicated area during the afternoon. In a weakly-sheared situation with about 1000 J/kg of MLCAPE storm mode will be single cells. The high bases around 3000 m AGL point to a distinct risk of (dry) microbursts that can locally produce damaging winds at the surface. In addition, some marginally large hail should be possible. The risk should gradually subside during the evening.

Sounds similar to my experience hopefully we can get some more but i'm not particularly hopeful but it'll be a nice surprise if there is more. You should keep an eye on the heavy shower around Chester which might give you one or two flashes.

I’m going to head to Firle and see if I can catch the side of that system in the channel ?

Wish we had doplar.. looking at the forecasted radar, there seems to be rotation on the hail core. Taking the East flank of that/those cells would be a great place to observe. Good luck down there.

On UKWW it’s been mentioned that the storms in the channel won’t cross to our shores. They are surface based and the channel will supposedly keep killing them off ?‍♂️

Conditions are great, it might cycle down but it will jolly well cycle back up when it reaches our shores imo.

Said later activity in the eml will though.

Meanwhile I think we could well be growing our own...
