    Although not the "storm porn" charts we were seeing last week there are still some possibilities for storms during the second half of this week and into the weekend. It is still too early to put any detail on this but something I will have my eyes on. Hopefully those that missed out may see something, but if not this week then we still have a lot of weeks yet before chances run out.

    I never seem to get storms in spanish plume events. Maybe its because of the Peak District being in the way. If the wind veers south easterly, missing the peak district, storms almost certainly will happen here. Had 5 last year due to this but still haven't had a proper one this year yet.

    It's kinda funny. Here we are "mostly unhappy" that the plume left us.. but by tomorrow, we will be frantically checking radars and satellites to speculate what will happen the following day. The fun begins once again. Some summers we are annoyed that the Atlantic has ruined our stormy potentials.. we end up finding we get more thunderstorms in October and December. This year, however.. the ingredients are there for summer storms almost every week!

    The summer is but young, we still have a full month of August so fingers crossed those of us that have missed out, will wait patiently for their turn. A classic Spanish/French plume still makes good photography as it crosses the channel (as people will vouch after the last weekend).

    There are always going to be winners and losers, thats the very nature of Thunderstorms if you are in a static location, if you get out and about then you have a much better chance.

     

    For Leigh On Sea it was a fantastic 4 Days, I would also say Kent and Dorset did very well also, this backed up by the lightning maps from the 4 day event.

     

    Thursday nights Storm was a bit of a bonus with a Bifurcated Trough pushing Storms North West and North East (The North-East part was not meant to happen but once the trough started to Bifurcate in the Channel it was suddenly game on) It was some of the best Elevated Lightning I have seen in 15 years in this part of the world.

     

    Friday Nights Storms were in 2 parts, The first part was from 3 Surface Based Supercells that were just the other side of the Channel near Rouens that drifted North on the Southerly Flow, This hit SE Essex around 9pm and went on until 1030pm, once again some great Elevated Cg Lightning and a beautiful Gust Front (Not as nice as the South Coast though)

     

    The Second part of Friday nights storms came along at 3am until 6am on Saturday Morning and was mainly IC Lightning with sporadic Cg's thrown in, the best part about this storm was the constant lightning for 3 hours lighting up the bedroom, it really was non stop.

     

    I was away for Saturday in West Wales at a BBQ But had chatted to some other chasers and we plumped for Oxford as a location for possible Supercells so would have been all over that (Sods Law) but was glad the forecast verified in that respect.

     

    I also missed Sundays CZ Storms that initiated over Leigh On Sea, Hail, CG Lightning, Flooding and damaged roads around these parts greeted me on my return at 6pm.

     

    Guess SE Essex was lucky this time around but am expecting other parts of the country to get in on the action end of this week as Easterlies at the surface are never good for locations East of London in Homegrown Storms, so maybe some of the members who missed out will be in the action Wed-Friday!

     

    Good Luck All!

    Got two spare beds, we're coming up your way on the next plume!

    Exactly...and some still find the energy to groan and moan. Thankfully a new thread exists for that :) is it in their nature or are they to be frank happier trolling forums, trying to stir up trouble...Bottom line remains and even taking those mega storms that hit parts of Germany not long ago. Some places no doubt managed to stay bone dry and without a single solitary rumble or flash? Those storms were quite incredible and admittedly something they're used too. Unlike us or given the last few Summers which have been on the best part pretty poor.2014 seems to be different for a (refreshing) change - anyone who hates storms are lucky to live in the Uk if we are honest. Thursday into Friday may well just be typically thundery showers, or indeed nothing untoward. Frequency of thundery episodes up massively since last year, even yes here in relatively storm starved Shropshire. Mustn't grumble despite some of the negativity.Roll on the next :)

     

    Since I started chasing storms in 2004 this year has already surpassed any previous year for the amount of storms I have seen. Not all of them have been big storms, some have been little thundery shower type affairs but some have been huge with two supercells on the 9th June and another possible one this past Saturday (not sure that the Ashby/Coalville cell has been confirmed as being supercellular although rotation from the ground was easily visible). I have seen a much higher incidence of hail amongst storms this year too. I know some people have still missed out but in the end everyone's time will come.

    It's been a good year personally but I don't buy into this "hopes dashed" idea. The very nature of showers and storms is that there will always be areas that miss the action. In future, I would suggest people manage their expectations when they see that they are in the zone for storms. I was in the zone on Sunday, it didn't happen for me, that's life, there's bigger stuff going on in the world to get angry about.

    The very nature of the weather "unpredictable" is what makes it all the more exciting to keep doing what we love. In a sense we gamble mentally on whether or not the storm will hit us which is shown in our "hyping up" period when huge swathes of CAPE are shown on forecasts.. or ESTOFEX.. TORRO, Metoffice.. BBC.. warns us of severe weather. ~ the cost of our gambling.. sleepless nights.. caffeinated rivers running through our bodies. Earlier in this thread someone posted a video of lightning striking just in front of him. What an incredible thing to capture on video.. I wonder if he was a regular storm nut or just someone who liked that particular storm!? Part of staying up and capturing the perfect video is also gambling. ~ Will the storm hit.. will it sound good.. will something interfere, will the lightning bolts be visible. These things keep me going! So again, looking ahead to this week. Nothing to say we will have anyway near the amount of activity as we did over the last week. The thrill of a chance to catch another storm is enough! Cameras armed, memory cards loaded.. and be ready to shoot!

    Interesting to see another timelapse of this storm. This is my first post since Saturday but I also have a timelapse of this which clearly shows a rotating updraught/wall cloud, as I ended up chasing this storm to all the way past Oxford!

     

    My account of things is I chased the line of storms that went into Dorset and caught the last storm. Then noticed clearing skies so went up the A303 just past Stonehenge and up towards Swindon to see if any surface based storms would form and follow on from the previous ones. By that time the storm was developing so followed it (at first stayed ahead of it) from there. It was producing near constant thunder and saw some lightning, but It's right move caught me out a little though so was often on the N side when would have preferred to be on the SE'ern side.

     

    I realised this and drove east towards Oxford, apart from one time I was just following road signs (A40/Oxford) without a destination set on my satnav, yet I somehow ended up going westbound on a duel carriageway away from the storm! that cost me a bit of time. 

     

    Then drove east towards Oxford into very heavy rain out the back side of the storm (including the sun shining with a rainbow at the same time), took the A34 NE from Oxford through torrential rain on the northern side with quite a bit of surface water on the roads but managed to punch through the rain and get ahead of the storm briefly.

     

    Ended up a few miles east of Bicester and where I shot this brief timelapse video, before the wind picked up and blew my camera off the only place to balance it (also the wind moved it not me):

    http://youtu.be/HGWx63ioA00

    A bit wonky as could only balance it that way. Note the Gopro's wide angle view makes it look further away than it was. Also the exposure isn't quite right, to the right was heavy rain/hail shafts that don't show.

     

    I could immediately see it was probably a supercell when I eventually found a place to stop there (hedges etc often annoying away from busier roads/houses/trees), with clearly visible rotation and quite rapid cloud motion too.

     

    Then it passed over with torrential rain and hail up to about ~1cm size, however I drove to my south/SW where I had seen very heavy rain/hail shafts quickly drop down a bit like a small microburst, and found hailstones up to 10p (about 1 inch) diameter scattered amongst smaller ones on the ground.

    Found a few smallish branches down (as well as leaves presumably from hail) in one place showing evidence for stronger gusts.

     

    I have more video including the hail/torrential rain to edit and upload at some point. Some pics I took:

    As the storm moved away: Posted ImageIMG_2341.JPGPosted ImageIMG_2344.JPG

    Hail found slightly SW of where I filmed the rotation: Posted ImageIMG_2348.JPGPosted ImageIMG_2349.JPG Posted ImageIMG_2351.JPG

     

    The first time I've seen hail that size (even if the 10p sized stones were just found on the ground), and my first probable supercell. Makes the at time frustrating driving worth it.

    I chased that very storm! Was driving down into it and stopped at Kiddlington (?) to watch. Constant rumbling and some of the lightning I saw but a lot was IC.

    Saw a low base on it in the distance an headed out down some o the country roads ending up in Lurgashall (?) where I got some pretty awesome video of it and photos. The cloud was green at one point. Simply stunning to watch - and so close too!

    Whether or not it was super cellular it definately had rotation and caught an image of what looks like a very localised microburst.

    I'll upload vids and photos tomo - on my camera and need a pc to get them off

    Well everyone has gone all gun ho on me :p I only read what Estefox had to say, and sorry but most of it did not verify as they alluded I understand how unpredictable these sort of things are.

    But I've always known them for their accuracy, not at all angered by the lack of storms, I'm angered by the expectation which drilled into my head - I can't help but think it could have been a whole lot better.

    However that's the nature of storms, they leave you begging for more. I'm sorry just a tad deflated after being awake many hours, which came to nothing. It does not apply to all of you, Some win some lose. London seemed a good bet, going by at the time.

    Tuesday morning silly question..

     

    Last week with all of the lightning, why did we not hear thunder every time there was cloud to cloud lightning, but we did cloud to ground?

    A lot of the lightning was elevated during the weekend there were a couple of cloud to ground strikes here and heard a lot of thunder.

    If a storm is elevated then lightning can be a long way up in the clouds and thus the sound of thunder cannot be clearly heard. If an elevated storm produces a CG this will produce audible thunder as it has travelled from the cloud to the ground and so is not taking place high in the clouds.

    Especially at night you can see lightning that could be occuring thousands of feet up.

    Estefex was actually  quite correct you must remember to qualify it within a probability of  'x'  amount of miles  of a given point,  i would have said 50 miles would be correct, you can not predict much closer even the NWS and NSP centre in the US do not normally predict severe weather in less than that distance.  the Oxford Supercell was almost within that distance of you. As to what you get with that type of storm even a mile can make a difference as to what you get one side of Bicester had 1" hail the east side just rain.

    So on our small island draw a 50 mile circle on a map around Oxford that will cover a large area the storm top when near Oxford was so high it was visible from Portsmouth i personally  watched it from near Brill in Buckinghamshire and at one time drove under the edge and got caught in a torrential downburst soon got out of it to watch it start to break down to the north east. Remember just because storms of any sort are predicted does not mean you will personally get your own

    Well generally speaking ,we had a good thundery spell over the weekend and of course thurs/fri .it will always be the case that many will miss out and many will get their overhead or near storm ,i did well but of course it was better further east or west ,there used to be a time when i,d stay up most of the night if a storm was possible ,but now i say to myself ,leave the windows open if its that close it should wake you up .as for the possibilitys this end of week ,if your under one it could be good ,sometimes in these sort of situations something good could turn up on your patch .lets hope those that missed out will get their turn ,Chill out and crack open a STella [or two ]  :drinks:

    would not be shocked he got static charge too being this close.  There was story in paper about woman being close to one she now gets a shock going near things like radiators Tv's etc..

    They always say that but I dunno if the science would really support it. Stuff like "well lightning struck my house in '72 and I've never had to change my underwear since" or one bloke I remember says he never has to wear jumpers since being struck years back - but how would that happen? Does it melt your DNA or something?Surely if it had that profound an impact it would mess up your health?As for people retaining some sort of charge afterwards, that can't be possible can it?

    It can certainly mess up the wiring of your brain. It has been known to heighten people's senses and such after being struck as well as some less desirable effects.
