Again today the parameters are there for heavy showers and thunderstorms breaking out in the afternoon. Perhaps not as widespread as yesterday and wondering if they might peak in central midland counties mid /late afternoon.

THUNDERSTORM OUTLOOK - SAT 9TH JUNE 2018
Synopsis

A slow moving upper low over Scotland will gradually lift NE, with a slack pressure gradient at the surface tending to lend to sea breeze convergence inland ... which will be the trigger for a swathe of heavy downpours with thunder to develop over Scotland, Ireland and N. Ireland in particular ... where atmosphere will be most unstable in proximity to upper low.

... IRELAND and NORTHWESTERN BRITAIN ...

Proximity of upper low and associated colder air aloft across Scotland will create steep lapse rates with surface heating, with peak heating in the afternoon yeilding 300-800 j/kg CAPE according to some models. Sea breeze convergence in slack flow regime toward western side of Britain combined with some upslope influences and large scale ascent of upper low drifting slowly NE will be the main trigger for likely swathe of heavy downpours with thunder to develop across Scotland, N. Ireland and Rep. of Ireland from late morning and through the afternoon. Generally light winds aloft and rather weak vertical shear will lend to pulse-type storms, though convergence zones may merge these areas of slow-moving storms together to increase the risk of localised flash-flooding. Isolated incidences of large hail can't be ruled out given steep mid-level lapse rates and CAPE values, also there is potential for funnel clouds to form along the convergnce zones - which may lengthen into a brief weak tornado. Any storms may also produce frequent cloud-to-ground lightning- which may pose a hazard to those pursuing exposed outdoor activities.

... NW ENGLAND, WALES and SW ENGLAND ...

Isolated heavy showers or thunderstorms are also possible further south across NW England Wales and SW England ... again due to sea breeze convergence or orographic lift. Localised flash-flooding is possible with any of these storms. They should quickly fade after dark.

... CHANNEL ISLANDS ...

Elevated thunderstorms on northern edge of warm moist plume will bring a risk of localised flooding and frequent lightning this morning. Activity may weaken for a time before more storms form over northern France and drift over the islands.

Upper low / trough over Ireland today

hawkwing

Looks to be kicking off now in West Tipp.I'm 30 miles east of the action (for the moment)...

I was in Kilkenny City earlier and it was mostly clear skies and very warm. Moving to the north of the county and it is noticeably cloudier albeit sunny with clouds building.

Clouds building in Kildare now

Have to take a spin to Cavan so brought some gear just in case.

I see some interesting clouds to my southwest too.

redsteveireland

Stubborn cloud only starting to clear in Galway now, patches of blue sky appearing. Enjoy the sparks later.

Four Phucs Ache

Big dark cloud over portarlington now

Moving slowly south.

Kind of agree alright. Given the heat out there, I was expecting things to be very lively already. But sure we live in hope...

Storm 10

What happened today is there too much cloud cover, here in Galway it got cloudy last night and still full cloud cover no sign of anything happening

DOCARCH

Lone sferic showing up in Offaly/west of Edenderry.

Oneiric 3

You can literally see where the main trough is lying on the 3 hr met maps (I put in a rough take in blue)




Summer showers are funny, they can develop sooner or later than what the models predict so I'd not lose hope just yet.

Fairly ripping it asunder over Highland Scotland right now

pad199207

Cap may break later on in some midland areas.

spookwoman

First strike of lightning registered now i think edenderry area

jimmynokia

Just leaving Cavan town back for Dublin and huge wall of cloud

Rikand

My theme for the day

Did someone forget to throw the switch :pac:

Seen nice convection up around Limerick moving inland but little showing up as yet in the way of rainfall .

Oscar Bravo

Lightning around the Mullingar area now

Larbre34

Much potential in Kilkenny city? Hurling match at 7pm

dexter647

Staring to rain here now with a few distant rumbles...South west Laois

An Ri rua

Hearing first thunder now in Mountmellick. I see from Met E that there's lightning strikes in Clonbullogue/Bracknagh region.

KildareP

Distant rumbles in Edenderry

lolie

Can here thunder rumbling but getting washed out of it with a downpour so can't go out to check for flashes.

redsteveireland

Kinnegad looks like a good spot for action at the moment

Meteorite58

Around Monaghan and Baliieborough seem to be the main areas of activity atm

wing52

Rumble of thunder in portarlington

Meteorite58

Cloud line bearing rain / lightning very thin, wonder how much left in it since it got going so late . Temperatures quite high still.

Say my name

Just for a bit of amusement.
Go on to blitztortung.org and look at the European map and see if you can see what I can see.

There could be a break of 20 seconds and suddenly all of Europe will be struck with lightning at once in a huge crescendo.
Another break and the same thing again over hundreds if not a thousand miles.

Pretty cool.

So far today

Had more or less a rinse and repeat of yesterday here (SW Laois). It was extremely warm around 5pm with pretty impressive CBs building, then 20 minutes or so of thunder followed by huge downpour. Looks like the same again tomorrow!

The 70's built home my parents bought in Scotland had a lightning rod on the chimney. I wonder when they stopped fixing them as standard to new builds.
