Convective Storm/Discussion thread - 02/09/16 onwards

[Wet'n'Dry]

I've not seen a warning like this!!

http://www.metoffice.gov.uk/public/weather/warnings/#?tab=warnings&regionName=ee&fcTime=1473980400

An area of torrential, thundery rain is expected to develop across the region during early Friday morning bringing the potential for exceptionally large amounts of rain within a few hours. Frequent lightning and hail may be additional hazards. Whilst there remains some uncertainty about developments and areas affected, there could be major disruption. Please be prepared for the potential for very severe weather conditions bringing flash flooding and disruption to transport.

A cold front approaching moist, unstable air is expected to generate a line of exceptionally heavy, thundery rain. Possible sustained hourly rates of more than 30 mm could result in totals of more than 100 mm in 3-4 hours. Particularly in urban areas, this could lead to flooding of properties and businesses and major disruption to transport.

Wew, I'm off to bed with the windows and curtains open in the hope of any thundery activity waking me up. 

 

I do hark back to the storms o  the 1980' - mid 90's.  They were the best in this corner of the UK.

[Flash bang flash bang etc]

WE'RE BEING STONKED!!!

Well,maybe the motorway theory someone cited earlier has some credibility. An earlier M4 line,no one hugging the M25

Seems to be forming along the North Downs escarpment from Farnham to Swanley (NW Kent) - orographic lift?

Sounds like a red warning rather than amber but I guess it would be red only if they could pinpoint specific areas. Looks like any activity for the Midlands is out now

The band looks to be weakening now. Ill give it another 15 mins then bed time with the window open i think. 

[Wet'n'Dry]

Goodnight all, I have to get up early for work.

I hope you all get what you're looking for over the coming hours. Stay safe and get your pets in!

[Thunderstruck]

Right, going to sleep now, got to be up early tomorrow for school. Could do with not being woken up by a storm but if I am, I am. Enjoy whatever you may get everyone, stay safe, and I look forward to checking back here in the morning

[toggerob]

Unsure wether to go all-night with this as for the NW it's fairly borderline in terms of how far west the cold-front initiates convection. It's not until around 4am that things are forecast to get going across the north and midlands.

[joggs]

Goodluck all. I had my stonker a couple nights ago up here in West Yorkshire.

I'll be radar watching for a few hours hoping it explodes for you guys who are storm starved.

Came out of nowhere!

Unless that arc can develop a little bit more on it's Northern side, i don't think it'll make it here, Bournemouth at best.

Dunsfold aerodrome taking a near miss

[Southern Storm]

This is it boys and girls, from now on it's going to be one hell of a ride, enjoy the storms and stay safe, I'm off out with the camera, I hope to return with some nice shots.

[East_England_Stormchaser91]

definitely a speck of precip over on the Cambs/Northants border. 

Anyone else love how the storms have formed in the form of a Thames streamer?!

just popped out into the back garden for a cheeky smoke and can see distant lightning from the storm near Winchester (a good 45-50 miles away as the crow flies)....nice

Webcam in Rotterdam, some pretty impressive flashes although the storm isn't half as potent as it was when it was over Eindhoven. Seems most of the energy for that batch of storms is over East towards Arnhem

BRILLIANT !

[Mapantz]

It does look like things are starting to destabilise in between those two areas of showers, the one in the channel, and the one East of Winchester. Development just to my West.

[Mapantz]

There we go... bang on cue!

[Mesoscale]

Im going to call it and say im too far north now unless some serious forcing comes into play. I saw some incredible storms earlier, although I didn't get a drop of rain the structure and the cloudscapes where insane. It was the first time I have ever seen mamatus and I watched multiple updrafts become anvils.
