    One positive out of this is that i can see some explosive convection now over the West Dublin and into Meath moving NE.
    Some nice angry skies.

    Recording another time lapse of that :D This is the current view:

    Also looks like a heavy shower passing just east of here.

    Rain strating heavy now, good few intracloud flashes and sharp blasts of thunder...still murky as hell though

    That cell has just died and was dying over the last 15mins.
    30 miles SW of you and it was a very healthy storm.

    Over 400 strikes from that beauty.

    Looks like an inflow trail cloud to me. I'm no expert though. Great pic!

    I often suspected that this place was cursed with regards thunderstorms (amongst many other things), but the latest radar has just confirmed my suspicions:

    APPLE.gif

    Notice the perfect circular clear spot I am under. I think witchcraft is playing a large part in this. Not one single drop of rain despite end of the world cloudscapes. Raining all around me, everywhere, but not here. Thunder has ceased as well.

    Roll on winter. And destroy this place with storm. :mad::mad::mad::mad::mad::mad:

    Yup, I see Dublin's in a forcefield too. I'm off to have a word with our local weather gods, Rainius and Mistius. Where's Zeus when you need him?

    Massive CBs going up to the northwest and north of me. have the camera recording them. They flew up. Those clouds in Meath look really nasty. I'm awaiting a rumble of thunder now. Looking good

    When you see them, kick 'em in the nuts. Hard. Then do it again. Saying it is from me.

    Then kick them to death. :mad:

    Lol Paddy.

    @Highdef, they sure have exploded up. Nice side on view of them here with lots of nice cirrus intortus overhead in the dry slot. These CB's are maturing nicely still as there is lots of nice high dry air aloft across the east.

    Edit: It looks like it's lashing near you as i can see the rain shadow from here and it's moving ENE now.

    An awful lot of rotation and swirling of clouds and steam/mist at low levels as that passed through, really strange to see the low level cloud moving SW as the higher clouds went NE, the anvil is passing overhead now but no mammatus :(...haven't seen anything like that in a while, got some pic and video, have a look and see if there's anything worth uplaoding...we did end up with a few more strikes but the mountains seem to kill what was left of it. Raining lightly now.

    Maybe not. Check out the clash of airmasses over Ireland right now:

    sat-2045-20080806-161-188.gif

    Low feeding from the SE, occlusion to the NW. Land low in the middle!

    Could well be a lively night for some (NE half of country more especially).

    Thunderstorm back on here, with explosive cloudscapes to the south and east again. Clear to the north west.

    Edit. Approx 2 rumbles a minute now, clouds becoming increasingly nasty to the east, but clear spot making bee line for here.

    Look beyond S, there is a trail that is moving ever closer to you. Showing no sign of dying at all!

    Storm to the east is moving very rapidly away. No wind but clouds are moving very fast towards the southeast. Nice clearence all but upon me now.

    I've seen better. :rolleyes:

    @ DOCARCH, Yep convergence is not being aided by surface heating. Cloud tops are not getting high enough it seems even though i witnessed a Cb exploding half hour ago before low cloud rolled in.

    Looks like the skies are about to open here in Balbriggan. The low clouds overhead are moving from the south, as they have been all day, but I can see other low clouds at similar height not far west of here moving from the northwest! Always an onimous sign weatherwise!icon10.gif

    Snowbie, that cell you mentioned went up before my eyes. Passed just to my north, clipping Dublin airport. Lots of interesting clouds around. Got some nice rotation on video too.

    Nice bit of Thunder and Lightning here but the rain was torrential, still raining but not as heavy the Thunder seems to have died away at present.

    Got a few shots of flooding but none of the Lightning.

    Surface winds have gone into the SW here but all signs of lightning has disappeared. Very dark to my west with heavy rain inching towards here.

    Just started to pour here now. Just like flicking a switch. We're just on the margins I'd say. It's just stopped now but it has just come back lightly again now! Mad! Very big drops

    Thanks Confab, If I had the camera in the car going home from work I could have had a few of the Lightning as there were a number of pretty big forked ones.

    All appears to be falling apart now. Skies still look very chaotic and I can see rain to my north but not much more development now. Will get some interesting video up online in the coming few days.

    Shannon had about 48mm this afternoon, wouldn't surprise me if it was most in a hour or 2.
    Haven't seen the 9.25pm forecast

    38.2mm in an hour at shannon IIRC. http://www.rte.ie/news/9news/ <<< CLICK on Weather Forecast for a replay. It may be after 10pm by the time tonights cast is on there.

    The 60 minute record for the most rainfall at any Irish Station ever was broken.

    ok the video of small funnel cloud and storm now uploaded if you want to have a look.it was recorded in trim at around 5.45 when the convergence whas crossing the north east of the country.think this is the tail end of the storm that caused alot of lightning in navan, slane and Drogheda

    Finally squeezed a drop of rain from the constant nearby shower. A whopping 0.6mm. Amazing the difference a mile or two can do with regards rainfall in these set ups.:)

    But now, the fun begins ;)

    Didn't Phenix Park in Dublin record twice that amount last year in the same amount of time, or is that for a different timespan? I think something like 76mm or something.

    Just looked it up, obviously not. Max hourly rainfall last June was 29mm, while Phoenix Park 90min total was 26mm out of a daily total fall of 53mm. on the 22nd June.

    http://www.met.ie/climate/monthlyBulletins/jun07MWB_lores.pdf

    Although I am sure I read somewhere there was an exceptional total from a thunderstorm at Phoenix Park sometime in the past. Do you have any information about this off hand Mothman? I'd nearly swear in was in the 70mm range.

    Tres cool man (you could have edited out the last 8 minutes though :)), just a coincidence that Network 2 showed a mock drama-documentary about a super-tornado hitting Dallas, Texas head-on this evening too.

    Absolutely torrential in Galway city around 5:30 today, one of the heaviest rain showers I have ever been in, drove 10 miles up the road and it was bone dry - weird.

    I am not surprised. The main river that flows through the town I live in is extremely high at the moment, and is flooding in parts. The amount of rain that fell today within two hours was unreal.

    We had round about 30mm from a large shower here this evening between 7.45 and 9.15, twas biblical at times. I caught some pics of the shower as it approached, and have posted them in the weather pictures thread.

    Just checked this out on Torro

    ***SEVERE THUNDERSTORM WARNING***

    For East Sussex and parts of Kent, issued at 22:00BST Weds 6th August 2008:

    Radar indicates that a thunderstorm capable of producing large and damaging hail is located close to Newhaven and Rottingdean at 22:00, and will move NE at abour 35mph. Residents of southern and eastern East Sussex, and western Kent should take shelter if severe weather approaches, away from windows. Severe winds are also possible

    A TORNADO WATCH is in effect for the area - severe thunderstorms can produce tornadoes with no advance warning. There is at least a small risk that this storm could produce a tornado.
