Presumably the Dublin mountains won't have a significant shadow effect on 25,000 ft topped storms?

It may in fact be the hills/mountains that are triggering these cells through orographic lifting.

DOCARCH · 12-05-2021 3:58pm

Dark clouds approaching Dublin 16 from the south west.

igCorcaigh · 12-05-2021 4:04pm

Meh. The Munster rain band seems to be disintegrating.

Planet X · 12-05-2021 4:13pm

Sth. Dublin.
Left work early on the push bike after looking at the radar.
Home now.........just in time I hope.

redsteveireland · 12-05-2021 5:42pm

Beautiful views in Galway, just passing to the East of me.

Larbre34 · 12-05-2021 5:47pm

I saw 'snowfall' trending on Twitter and I thought, crikey, those downpours must be dropping the temperature like mad, till I spotted it was the name of a horse that won for Aidan O'Brien earlier at York! ðŸ˜

redsteveireland · 12-05-2021 5:55pm

Boom! Flash and a really long rumble, excellent.

A new line of thunderstorms forming from Galway to the north east and and moving south eastwards

Incredibly poor stuff from Met Eireann, who didn't put Galway or the North west in general in their yellow thunderstorm warning earlier today. The mind boggles!

Dank Janniels · 12-05-2021 6:24pm

Heard a long heavy rumble awhile ago in North East Galway . No sign of activity. Met Eireann shows sparks between Mountbellew and Ballinasloe.

Storm 10 · 12-05-2021 6:26pm

Thunder rumbling away from cell in Galway Bay
ME got this one wrong

redsteveireland · 12-05-2021 6:37pm

OK, a weather forecaster made a mistake, I don't see why why we have to mull over it every time.

MT called this today with showers moving South into Connacht from a front over Scotland fair play, it's disappointing when they don't happen

Storm 10 · 12-05-2021 7:00pm

Not a mention on that forecast after the news of the thunder showers in the West and Midlands

The only weather forecaster that is relevant to me is MT Cranium. He is head and shoulders above Met Eireann. Always excited when I read his weather analysis for the day and the coming weeks every morning, like a child eagerly anticipating Christmas Day. Terrific stuff.

Storm 10 · 12-05-2021 8:04pm

Pretty active storm moving towards Ennis

I live in Ennis and its pretty dark out there very ominous clouds gathering and just starting to rain now. No rumbles of thunder or flashes of lightening just yet.

It looks like it might miss you

Meteorite58 · 12-05-2021 8:56pm

Not much showed up in Kerry Cork after all. Some heavy showers in Tralee but even about 14 km NW there was little rain. The second feature producing more sferics, looks like it powered up from more diurnal heating later in the day. The occluded front looked quite stationary probably too messy a profile and never got enough heating going ?

Great capture by Nightskyhunter

Drexel_3 · 12-05-2021 8:58pm

Got some very heavy rain in Shannon a few minutes ago. Small clap of thunder

redsteveireland · 12-05-2021 9:53pm

In contrast, some nice lenticulars to close the evening.

Chris_5339762 · 12-05-2021 9:56pm

Sadly, it was just too cold and not humid and sticky enough for any decent storms. Cells were never going to form today, I don't know my ME issued such a wide scale yellow alert, but there you go.

Only got to 13C here in Cork, but once the rain kicked off it stayed below 11c.

Meteorite58 · 12-05-2021 11:31pm

Still under cold air aloft and showers breaking out again tomorrow with isolated TS possible more so in the Northern half of the country . The East might feature or N Leinster, again lots of areas of convergence aiding lift. Lapse rates good but shear is low so again pulse type storms again .

Storm 10 · 13-05-2021 11:55am

Heavy showers moving from the North along the West Coast any chance of sparks from them

13-05-2021 1:20pm

A lot of convection over the Wicklow mountains
Building and rumbling to the west of me too,on its southern edge in the south of the county only a few kms inland and tailing into north wexford

Was just popping in to post similar. A lot of dark and building cloud over Dublin Mountains.

Been looking at that all morning from my bedroom office window. Has been building all the time, wouldnt be surprised to see sparks from it later.

Meteorite58 · 13-05-2021 2:22pm

Yesterday afternoon's line of convection from Clare to the NE ( wrap around occlusion ??) into the evening showing up well on Sat24. Good lesson on how a feature moving into relatively clear air and afternoon heating can produce thunderstorms. I remember thinking that the DP was quite low for sparks but not so.

Hi DOCARCH any chance of sparks from the showers building off the West

Converging winds showing up well, more chance over land then off the coast I would think, nothing sparking yet in the West, could still do this afternoon, wonder will the convection build over Clare and produce a few sparks ??

DOCARCH · 13-05-2021 3:25pm

Activity has decayed over the Dublin/Wicklow Mountains (without a spark).

Typical lol. Hopefully over the summer months we get some T-storms coming up from the Bay of Biscay during a warm and humid spell

Yep, dissapointing, at least the sun held out here, I was expecting a dull evening.

Status Yellow - Thunderstorm warning for Donegal

Met Éireann Weather Warning

Scattered thunderstorms this afternoon and evening with a risk of localised flooding.

There was a Rumble around lunchtime on the south end
Showed an orange X on met Eireann radar for a while

Jpmarn · 13-05-2021 5:00pm

We had some threatening clouds near Limerick earlier this afternoon. But the activity has now died down to spotty showers at the time of writing. I had a video camcorder rolling with the hope of capturing any lightning for a time.

Donegal Storm · 13-05-2021 5:35pm

Big crash of thunder around 3:30pm during a hail downpour in Letterkenny

Risk of thunderstorms in Northern Counties tomorrow. Lapse rates decent there.

A bit more shear available, maybe a few funnel clouds again.
