It'll be twitter I'm afraid and I am sifting through to find ones with lightning

I could only stand at my hall door for this

Would need scuba gear outside 🤣🤣

Internet very slow here

Brief one of the rain but you can hear the thunder in the background

Saw some strong lightning out to sea there just now due east se of Arklow

And more

Lightning just lit up the sky to my east

RobAMerc

3 strikes south of us here in Dundrum in last 10 mins - getting closer by the looks of it

DOCARCH

Couple of flashes just off the coast here in Greystones.

Calibos

All the fun stuff seems to have passed to the north and south of me in Bray. A few 5-10 minute intervals of drizzle and light rain was all we got down the Seafront area all day.

Meteorite58

Just an indication of where the storms were today, from accounts only very few of the strikes recorded ,the ATD is tuned more for CG strikes.

That seems to have picked up the strikes over me pretty well

As per @highdef 's request

Here's 2 minutes of it on YouTube at the start of it

A very rare one where the thunder continued non stop with one rolling into another indicating a lot of lightning

Unfortunately my view at the hall door is restricted but you can make out one or two lightning flashs I think

I'm unsure how to embed youtube links on the new boards

Its a pity it wasn't night time

Not bad I suppose over Arklow but with 40 minutes of continuous thunder that you mentioned in an earlier post if all the strikes were picked up there would be maybe around 5 to 10 times that number of sferics showing up , Met Eireann do a good piece on it here . https://www.met.ie/climate/what-we-measure/lightning

Great video.

Yes the vast majority of the lightning must have been IC (inter cloud) and quite high based stuff considering despite being overhead it struggled to get very loud bar a few louder pops

Must say I was impressed with it,considering it was a home grown storm that built itself locally and got so very electrified

If you are like me and suffering major withdrawals due to lack of decent summer thunderstorms, then check out this very photogenic storm in Majorca LIVE right now :-

Was very nice looking as the sun set. Will probably be very dark soon though!

Jeez, what I'd give to be in Palma tonight

Meteorite58

ECM showing thunderstorm potential late Tues night but more so early Weds morning from midnight on moving into the SW, S and up through the country, more so the Western half , maybe the SE also, still evolving . Showing potential throughout the day further up the country.

So looking at very warm temperatures overnight ( after temps of 25 to 27C Tues ), as high as 17 to 18C for a time with corresponding high Dp's and temps getting up to the low 20's during Weds. A trough / occluded front associated with a Lp to the S of Ireland will be drawn up over the country with a high theta E reading . 850 hPa temps of 14 to 15C possible towards daylight hours. Areas of convergence especially in the SW and along S and SE coast and up along the W and NW coastal areas. Orographic lift in the SW, W and NW should help also. Decent amounts of LLS and DLS. Some localized heavy rain if the thunderstorms get going . Have found these set ups can really produce good storms at times but then at times nothing materializes . Met Eireann mentioning Thurs for possible thunderstorms but nothing yet for Weds, same as MT. WRF showing plenty of MUCAPE as Weds progresses .

Could be elevated storms in nature, ECM showing potential for a few hefty storms . Will they materialize , any thoughts??

Gaoth Laidir

It looks a decent chance for the South.

Kermit.de.frog

Scattered cells moving in to southern areas later tonight, not making much progress, dying out as they move inland. Then more up the east coast tomorrow evening/night and more widespread Thursday.

Some good downpours. Hard to know how prolific storms will be right now. Certainly looks like a decent chance of elevated lightning activity in the east.

Something to look forward to.

The dog was stuck under the kitchen table this evening and didn't want to move to go to bed in his box.

Very rarely the dog is inside and only time he's like that is when there's thunder. My father replied there must be thunder on the way. The sun is beaming down with ne'r a cloud in the sky. So I had to click in here to see and sure enough the thread is here and you've posted Kermit.

I'm in Wexford.

Blame it on Ted if it doesn't materialise..🤣

typhoony

not sure what areas are at most risk, latest GFS has the heaviest preciptation at 6am Thursday from South Roscommon up through East Mayo, Leitrim and Sligo

igCorcaigh

Good cluster of storms in the Celtic Sea, could they be coming our way?

https://www.boards.ie/discussion/comment/117859551#Comment_117859551

Exact same with the Cattle dog here

He couldn't be got out of the kitchen!

This always happens during thunder but never before it,something bad coming?

Over cork earlier - Mammatus clouds

https://twitter.com/littlemsenigma/status/1435312600431136770?s=20

Plenty Altocumulus overhead now near Arklow

1st pic looking north

2nd pic looking SSE toward the Celtic sea at the cloud bank,its a balmy 18c

Meteorite58

Nice convection and good cluster of sferics, interesting 24 hrs and Thursday to follow perhaps.

https://www.boards.ie/discussion/comment/117860308#Comment_117860308

Looks a standard direction of travel there for wave one

In the south coast/waterford spreading NNW that's tonight/morning

2nd wave enters via the east/SE maybe up tge East Coast points inland

3rd wave Thursday-Anywhere

JanuarySnowstor

Certainly interesting out to our Southwest!! Really balmy evening here in Cork must be warmest night for quite a while.

Will the storms move up over us? My gut says we have a decent chance between later tonight and tomorrow.

Though as ever nothing is certain and Met Eireann don't seem to see anything special which is noteworthy

https://www.boards.ie/discussion/comment/117860516#Comment_117860516

Thats it

Jinxed now

No storms for anyone especially Cork

Strikes showing up in kinsale on Blitzortung

5:13 thunder in waterford

interesting sky, clear sky out the back, went out the front with the dogs and saw these cool clouds. Raining now. Very balmy and thundery feeling.

Kermit.de.frog

There are storms in this airmass. Might need a bit of sun, some inland or close to land convection but there is potential today and tonight.

Indeed right now a line of thunderstorms sparked off south Clare/Limerick/Kerry.

The focus today is very much in the east (extending further northwest tonight). I think this evening is max chance for developing imports from Wales.

TheMilkyPirate

Rumbles of thunder here on the southeastern tip of the Wexford coast

Cooljaybeans

Thunder and lightning in wexford now

Kermit.de.frog

Not surprising. Instability and storms approaching the southeast coast. A weak trough line but enough to spark activity, moving up the coast through the day. Not always sparking but much more likely to be active as the day goes on, particularly early tonight.

I can tell straight away just looking out the window. The sky in charred here. Potential.

PukkaStukka

Sky is misty and featureless looking here in north county Dublin. A whiff of 1986 about it .....

Kermit.de.frog

Storms off the west coast are back building now to the extent they may effect west Galway and Mayo.

Cooljaybeans

Continuous rumbles of thunder to the east of me up the coast of wexford, sun is back out where I am

Can here thunder now in Galway city

I can see the storms to the south over Wexford

Here's some building cb's on the northern flank of the cloud bank

Then slightly to the left looking Southeast into NE wexford,the disturbed cloudbank starts

Danno

That Wexford storm looks lively, track through west Carlow, East Kilkenny, west Laois, West Offaly and North Tipp over the next 2hrs to 3hrs likely before moving in over east Galway and southern Mayo later if it holds.

Gaoth Laidir

This morning's 06Z sounding from Aberporth, across the water in Wales. The altocumulus sheet is evident from that saturated layer from 550-490 hPa. Also evident is the still very warm but dry lower levels, which would support surface temperatures of 30 °C today in the absence of cloud.

Since then a large cluster of lightning has moved up from Brest and is currently over Plymouth. Cloud bases there are from 8000 ft upwards, and Johnstown Castle from 6000-7000 ft, so it's all elevated convection. Most of the precipitation is evaporating in that dry surface layer, which is why the radar has been painting a much wetter picture than what has been felt on the ground.

A lot of lightning now in Galway

Big flash somewhere to the west of Galway rattled my house about 18 seconds later.

JCX BXC

Banging away in Galway city, some big cells and interesting sky scapes around.

Mad walking around hearing the near constant thunder, it's like 5 trucks trundling down the next street over.

Big flash about 10mins ago

Approaching here near Arklow

Hearing thunder

Fe*k sake, it went from perfectly dry to the most intense downfall I've ever witnessed in 30 seconds. Lasted about 5 minutes, lots of spot flooding.

I got absolutely soaked in the 20 seconds between the rain starting and me finding somewhere to stand in.

Sky this morning over Naas showing plenty of mid level instability

https://www.boards.ie/discussion/comment/117862186#Comment_117862186

Thats nearer than you'd think

High cloud to cloud lightning,hence the constant thunder but low volume as its maybe 20kms away or more above you

Louder when there's a CG

https://www.boards.ie/discussion/comment/117862242#Comment_117862242

Same here. Short little intense bursts that don't last long but drop a lot of rain and all falling form a nicely structured mid-level cloud base:

The odd low frequency boom at times too that sounds like cannons going off under the deep ocean.
