Getting the winter thread up and running.

Some Sferics showing up on the wintery bands of showers crossing the country as we await Barra.

DOCARCH · 07-12-2021 07:13AM

Clump of sferics off the west coast atm, west of Galway Bay.

Interesting, looks like an occluded front with high Theta E giving enough instability for some thunderstorms to break out. Were they elevated storms I wonder, I notice the ATD only picked up some of the strikes so thinking must have been a lot of in cloud activity . Blue lightning can indicate presence of hail. Dp very high this evening also at around 12C in the SE.

sudocremegg · 01-01-2022 09:29AM

Yep, it was 12c on the dot when the lightning started. It kind of came out of nowhere, calm enough day then the winds picked up drastically and the rain was torrential, but it didn't feel like hail at all in the city. Went away as quick as it arrived. Lasted about 30 minutes in total. Bit mad!

Only time I ever saw blue lightning was during an epic thundersnow episode in 2010 in Ringsend when I lived there.

Some interesting reading on lightning colours -https://www.netweather.tv/forum/topic/83505-the-colours-of-lightning/

Quite a few sferics off the Clare coast now running up towards Galway.

redsteveireland · 01-01-2022 02:19PM

Some action around the Aran Islands

DumbBrunette · 01-01-2022 10:44PM

Numerous lightning flashes visible towards the northwest from Mayo at the moment. Appears to be from a showery trough out in the Atlantic.

Showing up well on the Met Eireann radar too... about ~20 miles off shore from Belmullet

Regular flashes of lightning looking west/northwest from my own location near Castlebar continuing to give a very impressive light show tonight.

Stood out there looking north west. starry skies overhead and some lovely white flashes up towards Belmullet. High cloud tops. Someone on the coast getting a serious light show.

Would imagine that it must have been an impressive sight alright looking out to sea on the Erris peninsula. Did the same also and stood out in the garden watching it unfold. It was a good lively show there for a while.

Lovely to see the stars also. Orion in all his glory there in the southern sky at the moment. Nice to have a bit of weather interest to start the new year off!

Meteorite58 · 02-01-2022 01:29PM

Ferocious convective showers and becoming more frequent here in Kerry, hail and very squally. Fair bit of lightning showing up along the coasts today.

Heavy showers steaming through here this afternoon, some sferics showing over towards Loughrea.

SlowBlowin · 02-01-2022 10:39PM

Very heavy hail and lightening here at the moment.

NE of Sneem in the Reeks.

03-01-2022 02:10AM

Thunder in Cork City.

SleetAndSnow · 03-01-2022 02:11AM

Big flash of lightening and loud thunder in cork city, big chunks of hail too

03-01-2022 02:11AM

Hailstones and lightening in Cork City.

Just one flash. Was this expected ?

titan18 · 03-01-2022 02:11AM

Ya, wasn't expecting that. Think we got hail, then some thunder and lightning here in Cork city. Got very heavy suddenly.

03-01-2022 02:16AM

Very heavy rumbles. Haven't heard thunder that loud here before. It actually shook the hall door.

Some more flashes just now too.

03-01-2022 02:17AM

Rumbling away, windy also.

03-01-2022 02:19AM

Still flashing away from what looks like NW or the city centre.

Yeah the flash was really bright too, lit up the entire house which I hadn't seen before, even through the small cracks of the blackout blinds!

Jeju · 03-01-2022 02:20AM

Carrigtwohill here just passing over us now, large hail stones falling with it.

03-01-2022 02:24AM

Intense little cell. Showing up loud and clear on https://www.blitzortung.org/en/live_lightning_maps.php

I suspect that might be an isolated show for tonight. Doesn't seem to be anything following it with that intensity.

I don't see anything having tripped out on ESB Powercheck in its track, certainly nothing big enough to be noticed by their SCADA/operations management system.

Ozvaldo · 03-01-2022 03:24AM

Anyone can answer how the hell there's hailstones cork city when it's not cold mildest winter in years

03-01-2022 03:53AM

Thunderstorm cells often produce intense hailstones, even in mid-summer. It's because they draw moist air very high into cold parts of the atmosphere and it drops down as intense rain, hail or even snow.

It's more surprising to see intense thunder in Ireland in January though. I assume we're about to see the end of the mild spell and a shift to much cooler weather this week.

Ireland's location is one of the least thundery places on earth. We don't get dramatic clashes of warm and cold fronts, which is usually what generates them. That's why we get a tad over excited about a bit of natural fireworks in the sky.

Most of the thunder activity in our Atlantic systems hits areas like the west of France.
