Supacell

As AJ has said, please can we keep this thread to UK convective discussion and post about European storms in the dedicated thread. Some people have already moved over there, so please follow suit. That thread should be buzzing currently with all the excitement over there.

I have this one saved for midday on the 28th June from the 06z run of that day. I believe this is when the highest CAPE was forecast

It was further east than that, somewhere to the east of Cranfield and looking south.

Just a couple of pictures from last weeks storm chases

It has been a very good start to the storm season. As a storm chaser I have had my most active start to a season ever, although this could also be down to my having better equipment now for finding a storm than I did say 5 or more years ago. Let's hope for some more good convective periods between now and October This coming week is not bland for areas in the southeast. Around midweek there looks like a chance of some continental imports, although it is obviously subject to the usual eastward shift into Holland and Belgium. It is something for people in that corner of the country to watch though before, as you say, more continental goodness being hinted at in FI

A fantastic account of the damage caused by flooding as a result of some intense thunderstorms, much like has occurred in various parts over this past week or two. I will attempt to explain from my knowledge what may be to blame. The nature of the storms this past week was for them to form along convergence zones in an environment of slack winds at all levels (no wind shear but also very little storm motion), moderate to high CAPE and very high levels of moisture. This is a recipe for big storm clouds to shoot up and produce excessively heavy precipitation. Then, when one storm forms and collapses it sends out outflow which in turn provides a trigger for more storms to form and go through the same procedure. If nothing is moving, then the convergence zone remains in the same place and the storms form, mature and collapse along the same line and in around about the same place. If we get pulse storms with some movement of the air then we get the classic scattered thunderstorm situation where a few people see a storm but most don't. This is the frustrating scenario all us storm nuts know well. When you see a storm erupt on radar, produce numerous sferics and then die out just as it approaches. The same storm then reignites just a few miles down the road! Well imagine that same thing happening but nothing is moving.... you get thunderstorm, an almost lull in proceedings and then another thunderstorm but all in the same place. Meanwhile, somewhere just a few miles down the road may then wonder what all the fuss is about. Last week was a classic situation of some places getting an absolute deluge where others got very little.

Most likely won't verify but GFS 00z is a stonker of a run for late next week into the weekend. Nice to see the storm porn though

I can hear very distant thunder

Okay, enough of this I am heading out to chase

I think I may need to forget waiting for a storm to hit here and stick to chasing them Throughout this stormy spell I have seen some amazing storms but at home there has been very little. One small thundery shower on a fortnight like this last one is a bit poor. Still, I have had my storm fix but would be nice to see one over my house so I don't need to think about getting into position and avoiding traffic. Nope nothing here of significance i'm afraid.

Ooh a sferic just near to Trowell on a shower that is heading slowly this way. Please let it hold!!

It's a dry and sunny afternoon here. There seems to be a void of showers over here, although big towers are building to my NE and showers are actually moving today (albeit slowly).

Dry here with skies brightening. The last 2 weeks has seen my most active fortnight for storm chasing since I started back in 2004. For me there has not been a better convective spell for a long time when taking into account longevity and storm intensity. I realise there have been stronger storms but even the 28th June 2012 was a one day offer. Here in Derby we managed one storm on Tuesday. I am yet to edit that footage as still catching up on the weekends footage. I am loving that I now have a back log of footage to edit!

The storm to the east of Nottingham would be heading here if it was moving.

I wish I was on the Wash coastline just east of Boston.

Not such a good day around Derby so far, just lots of moderate/heavy rain. These cells are spawning and dying all over the place though. It would be a hard day to chase, unless you are in north Norfolk/Wash area :O

The odd rumble and some torrential rain. Went and had a drive round in it and plenty of water on the roads around the city.

Clouds are moving E to W over my house but showers moving N to S. Sferics around Burton on Trent.

Well as the showers/storms approach Derby they have become showers..... It is no wonder I go and chase storms rather than wait for them to come to me

I bet the M6 Toll is fun currently.

Do you know what, I think it is all moving very very gradually north and east.....

It looks awesome over Birmingham... enjoy

Some vicious looking downpours over Birmingham and another in Shropshire. They seem to be developing more widely too but moving very slowly indeed.

Looking at the predictions/charts I think the thunderstorms will be running just to my south today.

The sun is breaking out here. I am hoping the convergence zone is overhead today. Lots of sferics breaking out across Wales and West Midlands but shower motion is so slow it is hard to gauge which direction they are moving.
