  2. OK I think I can lend some credence to Vlad's story and the shelf cloud in York. I had noticed the development in the clouds and heard my first thunder to the NW at 19:30 and the convection continued to back build towards the SE very rapidly and we had thunder from two separate storms from about 20:15: one was a new one that had developed SE of the previous one and had skirted to my NW and the other developed to my SW and moved towards me. The movement was definitely to the right of the previous storms and the squall line that I have since seen on NW radar. This storm was accompanied by a very impressive shelf cloud - one of the best I have ever seen and I was pointing it out to my daughters with whom I was playing frisbee. This shelf cloud was accompanied by very rapid vertical motion and associated rotors beneath it and there were frequent tendrils of condensation beneath it. These could, at a distance, easily be mistaken for suction vortices but they were not: they were purely associated with the rapid upward motion of the saturated air beneath the shelf cloud. I have attached a piccie of the shelf cloud over Beverley but as it was taken with my mobile, it is not great. That said, it was a very impressive feature and stretched clear across a fair portion of the sky - as in a linear storm system. However, that said, that does not mean that this storm was not rotating: it clearly was and the differential lateral motion was clear to see as there was not a lot of rain associated with it (I think it was dying by this stage as the lightning was becoming very sporadic and there had been constant thunder half an hour or so earlier). This showed that the rear of the storm was moving East whilst the front was moving West and you could watch the scud make its way down one side and back up the other in front of you. So I can confirm what Mokidugway and SnowJoke have surmised and explain the observations of Vlad. I hope this helps and it certainly made up for the bust that was yesterday up here! Muff

  8. http://www.raintoday.co.uk/ tonight the odd shower around early but nothing to write home about heavy rain moving in from @3am-4am onwards temps 10-13 degrees ------------------------------------------ tomorrow one messy chart wind stays weak on a southerly however it could get breezy mid day on for all coastal regions and the far south east rainfall by breakfast rain around and some heavy effecting all by lunchtime by 2pm still raining but weaker for the far south-south east and most east coasts except the far north coast of out region all other areas likely to see heavy downpours which will clear all by about 5-6pm i expect the odd rumble where the heavier rain is but my call would be more anglia-yarmouth-norfolk areas by 8pm most areas clear but still a chance of the odd drizzle locally do not expect a lot of sun today temps around 14-16 degrees ------------------------------------------------------------------- tomorrow night still the odd shower for our northern region other than that dry and a more south west flow and winds weakening overnight temps around 12-13 degrees -------------------------------------------------------------------------- sunday a weak south westerly flow but will likely get a shade blowy in the afternoon rainfall the day starts dry but there may be a light shower to our far north west of our region but will clear quickly by afternoon should be dry for all it looks warmer around 17-19 degrees maybe cloud effecting the south coasts more today ----------------------------------------------------------------------------------------- sunday night looks dry and not cold although chiller than of late a variable flow but not windy rain --------------------------------------------------------------------------------------------------------------------- monday sorry not doing until tomorrow its too close to call one thing it wont be cold anyway have a good evening john

  9. Thanks SnowJoke. I should have gone inside and got a better camera but I was playing with the kids and even they eventually stopped to watch the show: it was a spectacular cell and I had a chance to explain the structure to them. Not often you get such a good view in this country. I have attached another file which is a close-up of the front of the shelf cloud as it approached. Here you can clearly see the condensation tendrils of the rising air beneath the shelf cloud. The kids were mesmerized with this and the youngest one asked me if we were going to have a Hurricane I told her no and nor were we going to have a tornado but she was obviously also taken in by rapid motion in the cloud base. All good fun: more of the same tomorrow please.......

  12. THERE IS A RISK OF THUNDERSTORMS FORECAST Synopsis Slow-moving upper low will continue to rotate across western Europe, a surface low will remain slow-moving across SW UK during Friday, a slow-moving wrap-around occlusion will lie across N England, W Wales and Cornwall with another occluded front across N/W EIRE and W Scotland. An unstable airmass across England and Wales will bring another day of heavy showers and thunderstorms. ... S ENGLAND, WALES, MIDLANDS and N ENGLAND ... Cool mid-level temperatures and surface heating will produce steep low-mid level lapse rates across much of England and Wales today ... which will support the development of heavy showers and scattered thunderstorms later this morning and through the afternoon/early evening. With yesterday's strong southerly jet over eastern Britain now displaced further east, vertical and speed shear will be weaker today, with 0-6km 20-30knts at best. So storms will be less organised then they were yesterday and thus a risk of severe storms is unlikely. However, any storms may produce hail, gusty winds and large rainfall totals in a short space of time - which may lead to localised flooding. Later this evening and overnight, a strengthening in the upper southerly flow across the near continent and SE UK may bring an increase of convective activity across SE England and E Anglia, as an area of heavy rain with embedded Cb bringing a risk of isolated TS drifts north out of the near continent.

  16. Thank you Muffelchen I didn't think I was imagining rotation. I was looking at the SAT24 vissable radar playback up until it got too dark to see another frame, and that particular cell on satellite did show clockwise rotation with a small up draft at the rear of the cell protruding above the rest of the anvil which looked like an overshooting top. This is evident on the sat photo's if anyone has access to some higher resolution images I'd very much like to take a look at them.BTW: Nice piccy of the approaching shelf cloud

  18. it was three small vortex that converged then made good sized funnel cloud near looking over humberston way hope others saw it. Got pick the funnel no vids. not good at explaining due to health just trying to give comentary how it developed maybe how all funnel clouds start. The storm was big heading to possibly hull. edit now storm given us downpour 5.2mm. check my gallery just posted sorry not good pic but all could do. There is two funnels small ropey one to the left, dome type in the middle, what not sure is flat based one next to it did develop from three vortex. There was alot activity I wondered if at one point there might of beeN a touchdown. http://forum.netweather.tv/gallery/image/19869-image054/

  20. Mainly cloudy,breezy and quite dull here today and feeling cool.just a brief bit of sun mid-morning. Now heavy rain has set in. Some bright echoes on the nw radar across a wide area of our region now. bands of showery rain swirling around the low currently centred over Wales. Not a day for outdoor socialising tomorrow either by the looks it. rain quite widespread over the country with that low stationary. Sunday does look a lot better though as the low starts to fill and the showers die away.Hopefully some sunshine to finish the weekend.

  22. Some really helpful analysis by many this morning. I had been thinking the rain threat for next week might diminish as we get closer to T0 - but with no model keen to give us a proper build of heights until T192+, there's a real risk that the GFS's conveyor of weak systems heading through / stalling over the south might happen. And therefore a risk of dangerous rainfall amounts, as highlighted. I just can't take the ECM seriously at the moment, it looks like a 2 year-old's first effort at drawing a sunset - there may be little of a jet-stream over us but I never find the weather that disorganised. I can only guess that all options except a freeze or a heatwave are on the table for next week, and that the north is more favoured to be driest - but I'm moving slowly to the 'very wet in the south' camp. Warming up quite quickly in any substantial breaks though?

  23. I cannot see where Estofex are seeing a 50% risk of lightning and tornado risk warranting a level 1 today. Maybe the models have changed overnight or something?

  24. I can think of many things that are a nuisance that warm, sunny weather brings. Screaming children, shouting mums, bbq's and drunkeness, loud music that people seem to think everyone else in the street want to hear, sweaty, tattooed torso's everywhere you look. Wasps, flies, the horrid smell of sunblock, heatstroke, sunburn, etc,etc...... As for the heating bills then maybe people should budget a little better. Shove a jumper on, you'll be fine. I'd pay twice the amount of my fuel bill if we had some nice cold weather and a decent Winter and be happy to do so.

  25. Started the day in Burlington and drifted west to round 2 of the DCVZ (Denver Cyclone) one limiting factor today was upper winds which were quite weak at 20kts. We got one of the best storms of the day near Byers and saw some decent structure for a time before it all fell apart. Drifted back west to near Burlington and shot some great Cg Lightning to end the day. Southbound tomorrow.

  28. Tomorrow looking similar in some ways to Thursday with an area of thundery rain (thus heavy rain with no thunder whatsoever) heading north and west with brighter skies and thundery showers following behind. CAPE values being shown by GFS and WRF are not as high as those on Thursday though so storms less severe or intense but considering I saw one flash of lightning it would not be too hard to beat my storm for intensity.

  29. Just had a very impressive downpour ,absolutely torrential rain but only lasted 3 minutes ,no thunder but gusty wind ,tomorrow looking good for some ,some angry looking clouds currently to my north over bristol and south wales but the sun is on its way down so i dont expect much untill tomorrow ,a very interesting week i.v seen several forked lightning displays and some good intense downpours so a good start to the storm season .regards meteor showers ,if its clear in you kneck of the woods keep an eye out ,although north america is favoured for any good show its not an exact science so we could easily get a good view especially towards dawn ,look towards the north but let your eyes wander around ,also last night some fairly good meteors towards east just after midnight one lasting a good 2/3 seconds like an oily rag on fire fairly high in the east moving south south west ,cheers gang .

  32. *changing details slightly to protect identity* When I used to work on a inpatient unit we would occasionally get a man in who had been hit by lightening when he was 15. He was completely fine except for every now and then as a result of the strike he would have an episode whereby he would 're-live' the strike accompanied with all the physical symptoms and have a complete breakdown for a couple of days and then be fine again and be discharged as if nothing had happened. It was one of the weirdest things I have ever seen, but apparently lightening strikes can do weird stuff to the brain for many, many years after.

  33. Hello Lassie. Of the 4 storms I saw in total only one passed almost overhead and that rattled through at a fair rate of knots. I set off in the car but couldn't keep up with it. The largest of the storms was the last one and that was to my east, more towards Wembley, Harrow way I would think. Quite an afternoon.

  34. Think 28th June 2005 had 60,000+ strikes, but if you add France in, it would easily top that ! Scary how its the 28th of June everytime eh !! Yesterday was a cracker for my area, car alarms, house alarms and the lot were going off, flash flooding was causing madness on the roads, and I followed that storm up to Sleaford. Witnessed some amazing CG's and even saw a c-c crawler near Bourne! At one point it looked like a small MCS as it passed North of Peterborough. Amazing how many bog standard people take note of the storms though on Facebook etc! People were freaking out about it all over, and the same happened witht hat night storm on 23rd July last year too. guess thats how rare and memorable good storms have become through the storm drought of 2007-early 2012 apart from those supercells Today looking not too bad, potential there for a few thundery showers.

  38. Hi Bluebreezer! I thought you would be seeing some spectacular thunderstorms yesterday! I was on the edge of things but could see lightning to my NW and North which is Northwood, Watford etc! I missed most of the showers and got about 20 minutes of rain at best, most of the thunder and lightning was just too far away!

  40. Well, long time not posts thanks to replacing aging pc. So not had a continuous set of 500mb anomaly charts. The output I have seen does suggest the NOAA charts below are probably the best guide for the upper air pattern over the 6-15 day period from now. ECMWF output this morning was closer to the NOAA 6-10 than the GFS output but neither showed much consistency with one another compared with their previous outputs really. So I would go with the NOAA output. Mind you none of the 3 anomaly charts predicted 7 days weather I got here, 7 days with maximum temperatures above 21C. The best I could suggest from them 10-15 days ago was 3 days at the most. Just goes to show whichever models we tend to follow, none of them are right all the time. http://www.cpc.ncep.noaa.gov/products/predictions/814day/500mb.php

  41. There is no consensus at all on next weekends analysis. I did the ECM last night (not seen the latest as yet) so a glimpse at what the GFS is offering. Well. A markable different upper air for a start with a north/south split with a high to the north and low to the south of the UK leaving the latter in a NW/SE orientated weak trough. Not good as it translates as wet. Totally different to last nights ECM so I would keep Mystic Meg on speed dial A touch more detail although I feel it a tad pointless at this stage. Still be bold. Friday Low west of Ireland and generally unsettled and wet for most of the UK. Saturday Similar situation with frontal troughs crossing the UK bringing wet weather to everyone on an easterly airstream Sunday The low has slipped down to Biscay but the easterly flow persists continuing the unstable situation with much rain about. Monday The low has slipped further down to the Med. And the Azores high is taking a peak in the SW but the UK still in a slack easterly with, surprise, a fair bit of rain. I’ll give the temps a miss.

  46. hi all today in croydon was the best storm ive had for ages anyway tonight http://www.raintoday.co.uk/ there are still some heavy showers around but should ease off through the night a very slim chance of a rumble but here at present some very angry looking clouds but only rain will feel a lot fresher tonight but not cold ------------------------------------------------------------------ tomorrow a southerly flow rainfall still possible showers to our very far north early and far south west but the north should clear just after breakfast most areas should be dry by around 2pm however the low is very close to our far south west of our region and showers may persist for a while later all areas look to be dry but a chance the odd light shower may get caught up in the southerly flow my call here is mainly dry and sunny temps around 15-18 degrees the wind will be breezy and will swing to an easterly as we head overnight ------------------------------------------------------------------------------------------- friday night an easterly flow north of london a southerly flow anywhere south of london will be quite weak there will be some drizzle early but heavier rain moving in effecting all before breakfast temps around 12 degrees ------------------------------------------------------------------------------------------- saturday winds will swing back in the morning to a southerly and will be gusty rainfall 8am heavier rain effecting all by 2pm looks likely heavy rain will still effect all areas note there looks to be a band of possible torrential rain for a time which looks to effect north of london this however is a guide and may end up further south if you get the heavier bursts the odd rumble is possible but not a high confidence on this rain also could stick around all day with this set up temps around 14-17 degrees so will feel a shade fresher ----------------------------------------------------------------------------------------- saturday night a breezy south west flow and could get windy on all coastal regions rainfall rainfall could stick until late in the evening however its looks to start easing off overnight temps around 10-12 degrees ------------------------------------------------------------------------------ sunday a breezy south west wind warmish 15-19 degrees but im holding off on this until tomorrow if that trough shifts slightly its the difference between being dry or sunny spells and poss storms anyway hope your all good john
