Big hail shower in Limerick about 30 min ago, with very heavy but very localised hail. A good 2-4cm of 2-5mm sized hail left lying on the ground. The strip of ground that had this hail on it was less than 500m wide though. Very localised. I have a few pics of the aftereffects on the camera, I'll be able to get them off and uploaded later on.

Radar loop suggests 20-40 mm rainfalls past three hours between Longford and Mullingar. Mullingar had an hourly report of 7.1 mm recently.

There was quite heavy hail and rain at times through athlone today. Very slow moving it was too

Would love to see those pics showing the demarcation of the hail

Looks like a band of heavy showers developing quite quickly now up through the middle/spine of the country. A couple of isolated sparks so far. http://andvari.vedur.is/athuganir/eldingar/i_dag_na.html

Rather intense cell passed over Waterford City in the last hour giving heavy rain hail thunder and Lightning.

Some rumbles of thunder in Sligo town.

Plenty of fork lighting and thunder in the ballaghaderreen area.

Loads of lightning showing up

Thunderstorm being reported at Knock airport now

I can see the sky over Knock Airport direction in the distance from my house and I can well believe there's a thunderstorm there. It looks incredibly dark. Meanwhile 25 miles west I have been lying out on the sun all day and have just realised I'm sunburned! If that storm is heading this direction it's doing it very slowly. Still warm and sunny in Castlebar. A very strange days weather here.

can hear thunder now in Galway city

Ya i live beside knock was plenty fork lighting and thunder right over head here.best strom i seen in few years here.downside power is gone.

Crazy flash of lightening and a massive rumble of thunder a minute ago. Power went off for a second and car alarms ringing.

Great hail storm to go with the thunder and lightening in Waterford!

Pretty sure I heard a low rumble in Galway half an hour ago, heavy shower with hail at the time. Very dark skies to the north at the moment

Great thunder and lightning show in Sligo earlier, pity i was doing an exam so no pictures or videos :-(

flutered

here at the butt of the galtees we had thunder from the time i went outside this morning 10.00am until i went inside at 4.00pm, it arrived from the east and traveled across the north of the galtees and the sliabh riah, we has only one heavy shower, from experience, if one gets a couple of fine warm days we end up with a long warm spell.

Found this on the Waterford City forum, some lightning

I was driving home from the west today and could see some deep convection to the north of me so i headed towards the core of the cell.
Passed through some crazy rain then i hit the hail core.. Listen to the noise of this it was deadly..

Plus i was trying out my gopro..

The most intense storm in a long time in Waterford City earlier this evening.Here is a short clip of the event.

Nice video, great crash of thunder right at the end there, can't remember the last time I heard anything remotely close to that!

I heard something considerably closer when a strike blew the roof of my house to bits yesterday! (see link to Journal above)

What I found odd was that it came from a flat grey sky, no cumulus type clouds in sight that I would normally associate with forked lightning. We got rain/hail about 15mins later then several strikes to ESB poles around the area over the next 3 hours. Power is still out.

Found bits of our roof and wall in the field 100 yards away, it was as explosive as it sounded!

robbed from my sister's facebook page. it's a still from a video she took yesterday outside ballymote

Upside-down wave travelling west is tracking towards Irish Sea at present from Cumbria and should track approximately Louth to Galway between 14h and 18h with potential for some embedded thunder and hail. If you're in that path, be on the alert for heavy downpours, hail and possible thunder. South of the track approx Dublin to Clare effects should be more of a steady light to moderate rain. North of the track you might be able to see warm front, weak warm sector then cold front and that could be rather squally (moving west).

Quite an unusual set-up, moving at a steady 40-50 knot pace. Lightning currently indicated with the "cold front" feature in the North Sea approaching Scotland.

Its also quite striking that this is arriving as a warm front (see synoptic charts), coming from the north. As you say, it is up side down. But the likely weather is interestingly different from the typical warm front that comes at us from a west - south direction. This one is being heated from below as it travels southwards instead of the more normal gently cooling of warm air travelling northwards.

Bsal

There was some very strong gusts at 1345 at Dublin airport from this small cell, at the time I was listening to ATC on the radio the wind was 360/29G50kts

DOCARCH

A few sparks out there this afternoon. http://andvari.vedur.is/athuganir/eldingar/i_dag_na.html Some small but intense looking showers on radar.

snowjon

Just had the first thunder of the year - just 1 clap with hail thrown in for good measure

jimmynokia

Incoming shower today!

Tornando9

Good chance of pulse type storms across the midlands today with some decent CAPE stretching from Cork all the way to Donegal.
CAPE in the region of 900-1100 j/kg which isn't half bad and with LI -2 to -3 should result in some short lived pulse storms.
Lapse rates are excellentso once the the convection gets going towers should pop up easily.

Heavy downpours are a certainty and hail embedded in the core of the storms due to the 0C isotherm at about 1500m

Negatives are the poor lower layer and deep layer shear which will result in un-organised storms. We want good organized storms to detach the updraft so the storms last longer and produce lightning.

Here are some charts from last nights hires 00z

CAPE an LI


Lapse Rates



Oc Isotherm for hail



Happy hunting.. T9

Iancar29

Its on days like this where we get nice cape and LI thats might get ya excited but its the shear and initial cloud coverage that lowers my expectations.
As T9 said , shear is crappy so it all be random pulse type events where itll be too hard to chase / judge what cells might build.

CLoud cover currently with light showers are only just hampering any latent heat build up .

If i had a car though and wanted to get out for the day id probably head towards Kildare/ Carlow region or up north , Fermanagh and the boarder region where best convergence seems to take place later on.

Some pockets of drier air around the convergences at 850mb too Ian could be the place to be alright. Atmosphere too saturated out west.

Nice beefy cell getting going near Edenderry now. Nice echoes for a single cell.
