You sure?... nothing on radar really


Looks good for later though if we can get some good surface heat for awhile

TS forecast for us today;

UKASF wrote:

... SE NORTHERN IRELAND, E IRELAND, N WALES ...

Scattered showers and a few thunderstorms will develop in response to diurnal heating and 500-600J/kg CAPE. Some slight shear may allow cells to become better organised/longer-lived as they cross the Irish Sea later in the afternoon and into North Wales. Given dry air aloft, hail is likely in many showers, with the potential for an event with diameter locally >2.0cm.

Else subsiding diurnal heating and slight ridging will cause showers to rapidly decay during the evening hours.

Iancar29

Yep , hopefully get something out of the showers making their way SE atm...

but ye , that cell off the coast of wicklow is looking nice... id be tampted to hang around howth head/ bray head today as cells go by , the lack of a car is my disadvantage though

Thunder here near trim with a very dark sky!

Beautiful TS just North of Swords right now, 4 strikes in the last 5-10min. Precipitation on the radar at 1800 showing 96mm/hr.

Nasty enough looking cell with some flashes passing just to my east into the sea.

Quite turbulent looking

Harps

Nice one all right, plenty of strikes recorded

Iancar29

Knew i heard some thunder from it... ARgh wish i was out at howth!!!!!

Have my camera recording it for a short timelapse of it soon.

sky is well carved up but it has lost it's spark as it goes oversea.

Can someone help me understand what the heck was going on over Swords-Rush-Lusk area for last 45 mins?

I riding (motorbike) on M1 filtering past thousands of slow moving cars, and it looked as if I was riding towards sci-fi Armageddon - it was a bit like something out of twister. The heavy dark cloud formation looked sinister and then the lightening started. I saw at least 10 different bolts of lightening (with veins?! and everything) across the sky, it was truly like a tropical thunder storm - I am sure some car passenger has got it all on their phone?

And then is started pelting down grape size hailstones. On the bike, moving at 20-30 kmph, even with the thick leather gloves and padded goretex jacket, it was like someone firing bullets at you. And within minutes there was about atleast an inch of water on M1. It continued like that for next 10 minutes or so. It was ridiculously bad - worst situation I have ever been into with a motorbike, or car for that matter. Close to J7/Julianstown exit, it gets brighter and normal again.

Yesterday was similar - heavy rain (not as bad as today though) around Skerries area, and nothing after that. I wonder what cause that area to have such a micro-climate - it's not like there's a huge mountain or lake separating them from rest of Dublin/Meath/Louth?

Serious cloudscape from that cell, pre tornado like!

Thanks a lot for the story! Very intense cell, just watching it move out to sea, serious looking thing, I wish my camera could do it justice.

Iancar29

SOOOOOO angry right now im not out up on Howth Head!!!!

Bsal

Some nice looking cells W and N of Dublin airport moving ESE. Might get a few strikes out of them before they cross the coast.

Another decent cell again to the north

Redsunset

Wow that cell which passed over the M1 looked impressive on radar. Thanks for the story.

I was out for this too in Laytown. Looking from Laytown down towards Skerries, saw some really impressive lightning I would guess over Gormanston/Balbriggan. Huge forks from halfway to horizon to well inland, with really good branching. Absolutely amazing stuff, never seen anything like it. The thunder was seriously impressive.

Very big Hail then torrential rain Dublin City Centre :eek:

Jets starting to punch through large build up now over Dublin airport and another huge anvil to the northwest.

There a mighty long Big Black Beast of a cloud formation running out to sea just north along the Liffey. I am on top floor of an Apartment block in Dublin 2 and feels like I could touch it , also I see the planes from Dublin Airport are aiming for a gap to get past it.

Radar of the "Long Black Beast"

Some from that cell over Swords that produced all the lightning , which i only saw the SLIGHTEST of a flash and roll of thunder from! :mad::mad:

These were looking north, then south as I took my walk along Clontarf seafront this afternoon around 7 o'clock. Its not often I have my phone on me so took a few snaps.

Ok what am I doing wrong here ?

Ok fixed it - hope they're not too big.

sirpsycho

I was directly under that massive cell around 6pm (Stamullen). Seen around 10-12 inter-cloud lightning. Plenty of thunder, it seemed to last forever, was great!

Iancar29

Not happy at all with all these amazing lightning stories! .. * shakes fist at you all !! * ha

... And nooo.. i didnt get enough while i was over in the states with disco style lightning!! haha


Anyways , Heres my short video of that cell from my view in Finglas... if only if it had moved more southerly
