Thursday/Friday: Lightning Storms, Flash Flooding Event Thread

R.F. · 26-06-2020 08:07AM

Probably one of the best thunderstorms I have seen in Ireland last night in Wexford. Got some initial but very loud clashes at about 10pm. Then woken up at 3am for a spectacular show which lasted well over an hour

Apologies for poor picture quality but a quick clip of the back end of that flashy shower that passed through here beforehand.

What did I tell ya about the Arome

Decent storm here in Donegal this morning, flash and rumble every 30 seconds or so for the past hour with some nice loud crashes, I suspect there'd be a lot more flashes visible if it was still dark. Nothing memorable but not a bad effort by Donegal standards, living in Australia and South East Asia for a few years has forever ruined Irish thunderstorms for me though I think

I only looked at one run from it the night before to be honest

and am still confused as to how they even developed this far west. But the ECM which I looked at regularly was more correct about last night's and this morning's potential from runs 2 days ago that it was in the more recent ones. Funny how that works.

Recorded 13.5mm here in Arklow mostly in a half hour with a peak rate of 120mm/hr
The 2nd Storm went on for over 2 hours and cut the power over a wide area
It's back here but still out in loads of places
The lightning was intense and frequent as was the noise

You guys definitely the big 'winners' last night along with north Connaught, west Ulster.

Fitzo123 · 26-06-2020 08:47AM

General consensus in Sligo is that that was the worst (best) thunderstorm in years, certainly in the 24 years I've been here, I've never seen the like.

Manhole covers were lifted from overflow, many streets impassable and about 3 hours of a spectacular light show.

The 7 day forecast rain map development posted by met Eireann yesterday morning was spot on in anticipating where storm conditions would develop. That intense area up through the north west in the early hours and some minor activity off east coast.

aidanodr · 26-06-2020 08:59AM

Not a whimper nor a drop of rain in Cork ( Carrigaline ) throughout this event yesterday, today. Just overcast and very muggy warm yesterday. Today just overcast and a little cooler. Nothing else to report, no excitement whatsoever.

Looks like the famous Cork Weather shield has held up again

Oneiric 3 · 26-06-2020 09:10AM

If I was to rate last night's event and this morning's event, I'd give it a 5 or 6, solely because occurred during the night time. I recall a fairly similar night back in either 2003 or 2004 (late July or August I think) that was was far more spectacular (for here anyway) and while lightning was strobey and frequent last night at times, it wasn't a patch on the day time storm we had a couple of years back during a hot June afternoon (forget the date but sometime before the onset of the drought)

Heat and humidity building quickly again this morning. UKMO hinting of possible thunderstorms in the Midlands and North Midlands this afternoon.

loyatemu · 26-06-2020 09:45AM

very violent storm over Greystones last night, we were awake for several hours, and it set off our car alarm. On a number of occasions the T&L were simultaneous, and the rain was like a monsoon. Certainly the biggest thunderstorm here for several years.

markfinn · 26-06-2020 09:47AM

So jealous.
It was a complete washout here with naught but a single roll of thunder at quite some distance around 3am.

pauldry · 26-06-2020 10:11AM

Rain up to 99mm for month now.

There was 39mm of rain last night from thunderstorm Sligo town

Markree only got 5.8mm

adocholiday · 26-06-2020 10:19AM

The storm passed directly over our house in South Wicklow last night and it was honestly scary. Definitely a good 30 mins of hammering rain and really intense thunder and lightning all happening simultaneously. I had to hit the trip switch myself because lights and appliances were going on and off of their own accord. Definitely the most intense Irish thunderstorm I've ever experienced. Forks of lightning were striking the ground all around us and the thunder was so strong you could nearly feel it inside you. A scary but amazing experience.

Xenji · 26-06-2020 10:38AM

Was awoken in Castlebar last night around 04.30 and not by thunder but the loudest rain I have ever heard here, the front dumped close to 10mm in about a half an hour.

Fitzo123 · 26-06-2020 10:49AM

Heavy black clouds building to the east of Sligo town again here.

Gaoth Laidir · 26-06-2020 10:51AM

That Wicklow storm developed from a shot of CAPE coming off SW Wales as low-level flow was from just enough of an easterly component to line it up. Up to 1200 J/kg MUCAPE materialised in the end, and the sounding from right in the centre of that highest CAPE east of Gorey shows the most unstable layer around 900 hPa. So Wales lent a nice hand in generating the lift required, so Mortelaro, you know who to thank.

Also shown is up to 800 J/kg MUCAPE in the mid-west, it too coming from around the 900 hPa level. The upper trough in the end did cool lapse rates just enough to tip the balance and allow this CAPE to be released over the terrain.

Outside of these two select locations it was a fairly dissapointing affair, with the strong cap wasting all of those high dewpoints and preventing surface-based storms from forming yesterday afternoon/evening. We might see some surface-bases storms form in north Leinster/north midlands this afternoon and move into Ulster, but behind that it looks a lot more stable.

Bitterly disappointing. Gave up watching about 1am when many others did too. Broken sleep and saw a few flickers after 3am and thought this is it. Nothing. Some rain for about 10 minutes. Near Enniskerry.

Really I’m only up the road in glencullen and there was a good hour and an half of thunder lightning and heavy rain it was class

That storm up over east Mayo/Roscommon and Sligo currently looks impressive on satellite.

Casting a shadow all the way over Co. Mayo and Connemara.

It was the best storm I've seen in years! I hope I don't have to wait another 20 years for a decent thunderstorm.

Will it ever end? The house is practically shaking here in Nth Sligo. Woke up to it at 3.16am and got an hour sleep from 5.30-6.30 when I thought it had stopped. But it's as bad again since. It's brutal.

I was woken at 6 with the noise of the thunder. Rain was torrential. But our house was shaking with the thunder. So loud! I fell back asleep sometime around 7 but it was still going

ZX7R · 26-06-2020 11:47AM

I saw about 6 flashes of lighting and ended up with a hangover this morning.

There was one particular bang of thunder here around 4.20am that sounded unnatural (certainly I never heard the likes before) that I can only only describe as multiple cannons being set off at once. Prompted the goose bumps to stand on full alert.

KingdomRushed · 26-06-2020 12:05PM

Last night was a no-show for Dublin pretty much bar the odd isolated crack, however, is there better hope today even though there is no expectation. I can't help notice very active convection over Dublin at the moment, skies darkening quite a bit, with some big fluffy clouds shooting up!

Yes definitely getting cloudier here in North Dublin

*eadaoin · 26-06-2020 12:09PM

Photos aren’t the best, just taken from a video on my phone, but there’s some nice lightning in them so thought I’d share. Saw a great show over the Dublin mountains from Dublin 8 (looking south west; the storm was a bit more to the east) and there were a few incredible rolls of thunder, almost constant rolling thunder for a while as it approached. Didn’t quite make for much in D8 though, the loudest thing was mostly the feckin seagulls!

Gaoth Laidir · 26-06-2020 12:31PM

Nice little convergence line setting up from Dublin northwestwards.

sweet_trip · 26-06-2020 12:35PM

I'm guessing south Kilkenny got no lightening last night or I just slept through it.

Not a thing, a few towers shot up to west near galtee mts but dissipated just as quick, that was about 9pm

Not sure if it's connected but in North Central Kildare, near the Meath bother, I've had virtually unbroken sunshine for several hours now. Clouds nearby in all directions but the clouds approaching from the south dissipate a kilometer or two before they reach my location. Really is a smashing afternoon.

Did it sound like what an earthquake might sound like? Because that's what some of it sounded like over here in SE Wicklow
I must say last nights ECMWF your comment on the earlier ones mean and WC's were pretty accurate

BobBobBobBob · 26-06-2020 01:52PM

Just started pissing rain in North Cork.

r93kaey5p2izun · 26-06-2020 01:54PM

I went to sleep at 6am. Nothing but distant rumbles at that stage (Clondalkin). Don't think there was anything more exciting than that. Glad it turn out so well for some though, some of the pictures are amazing.

Not sure what an earthquake sounds like but a few of the thunder rumbles in north wicklow were incredible.

Like a bomb exploding nearby.

DOCARCH · 26-06-2020 02:25PM

Decent looking storm now west of Omagh and some strikes in Donegal too.
