Quite annoying that my home place in Donegal did significantly better that I did today considering the forecast last night! Absolutely nothing here in London, a nice active front passed north this morning though the cold front was too progressive so no chance of heating in between for some proper storms. Donegal in contrast seems to have had a decent show

Amazing storm in Belgium this evening as well, most likely a supercell. When I checked the live view on lightning maps there was about 5 strikes every second and I've read reports of downbursts and baseball sized hail

That reminds me of the Ukraine v France match in Donetsk during Euro 2012

England match in Maimi suspended because of a thunderstorm!

None. CAPE values too low for a low risk situation until morning again.

You should have seen the radar of an approaching belt with lightning to the left of us lightning to the right of us [not much but lightning] and the well organised stream breaks in two and gives us almost clear skies, earlier on.

AND we had guaranteed high CAPE values that would have taken full advantage of even the tiniest bit of opposing volts values, but it split in two distinct clusters which gave parts of Kerry a short but good display and parts of Waterford had a strike or two and we had a gap.

Someone has the Cork shield on overdrive and if I find him, we'll both go down and put his generator out. :pac::D:mad:

bah, why is met eireann teasing us so with lightening right over cork for tonight?:(:(

seriously omg the entire north west got hit hard today and is still getting hit, it's not fair. i will help down the cork shield and smash it to pieces :mad:

lolie · 07-06-2014 11:35pm

Only had one storm here today but died off as it went overhead.

Plenty of rumbles but only a few very faint flashes that werent visible on video.
Looking at Flightradar earlier 2 US bound planes took a detour around the cell of the mayo coast.

My latest has a low risk from 02:00 through to 15:00. CAPE values plus 500J/kg by 09:00. {Sunday}.

Only a slight risk overnight along southern coastal areas.

By tomorrow afternoon then, widespread moderate risk with midlands and northern areas looking best.

Great shots, the third one is like a Paul Henry picture.

No lightening here in Kerry but had one large shower late afternoon where the temperature dropped 7C from 19.3C to 12.1C, no doubt the rain which fell started out as hailstone and melted on its long journey to the ground through relatively warm air.

Started to kick off.

RuthieRose · 08-06-2014 12:15pm

Nice rumble in the distance there. Cavan Town

highdef · 08-06-2014 12:18pm

monsoon like downpour here. Just getting the edge of the big shower in question. OH is on a jog round the block and no more than a few spits of rain where he is and there appears to be no threat of anything there. He's no more than about 1.5km away in an easterly direction, as the crow flies.

yesterdays thunderstorm activity in the West.

El_Dangeroso · 08-06-2014 4:07pm

Lightening right over Galway city right now.

Less than a second difference between lightening and thunder.

mountainy man · 08-06-2014 4:07pm

Nice thunder here and some heavy rain with a few hailstones thrown in.

Everything missed me yesterday, at least I'm getting some action today!

08-06-2014 4:58pm

There is some flash flooding on the N17 in Claregalway.

Hooter23 · 08-06-2014 5:42pm

Yet more storms passing west of Galway...

Storm 10 · 08-06-2014 5:48pm

Yes more thunder in Galway the thunder capitol of the West this weekend

R0C · 08-06-2014 5:52pm

Dark skies and torrential showers in Galway City. Feels very warm and sticky. Probable thunder but can't hear.

pad199207 · 08-06-2014 9:12pm

Hail from the isolated supercell over the Paris area this evening

Yeah I'm not surprised. CAPE and LI figures are similar to what you'd see in severe setups in the US let alone Europe.

... France towards BENELUX and NW Germany ...

Very dangerous setup will develop over the region by the late afternoon hours. With pronounced overlap of low-level moisture and steep mid-tropospheric lapse rates, models agree on the development of high to extreme CAPE values, with Central France towards BENELUX and NW Germany having the highest odds of seeing 3000 J/kg of MLCAPE by the late evening. As 500 hPa winds between 15 to 25 m/s overlap with backed low-level flow thanks to the presence of the surface trough, strong DLS (20-25 m/s) is forecast. By the late evening, with the enhancement of the low-level wind field with deepening trough, SREH values will increase especially over NW France / BENELUX (with values over 300 m2/s2 possible). Such setup will be very conducive for intense supercells / bow-echoes, capable of very large hail and damaging wind gusts. Towards the evening (beyond 18 UTC), as LLS strengthens, tornadoes will become a threat as well, especially if isolated supercells manage to persist into this time frame.

Latest model showing LI of up to -15 which is insane (-9 is considered extremely unstable) and a wide area of off the charts CAPE <4200 J/kg. I'm surprised Iancar isn't going over!

V_Moth · 09-06-2014 7:58am

Cells over northern France, Germany and north-eastern Poland with quite a few sparks. Also one out to sea off NW Donegal:

maquiladora · 09-06-2014 9:17am

LI of -16. I'm pretty sure thats up there with the lowest LI ever recorded in the United States, let alone Europe. Of course it's still just a model prediction, not recorded yet. Pretty cool to see from a weather nerd point of view :P Could be really severe storms there later, hopefully nothing too dangerous.

Strangegravy · 09-06-2014 10:34am

Fantastic cloud structures over east Limerick at the moment, heading northward. If they develop more could see some major sparks up the country in a while

Harps · 09-06-2014 10:36am

Already some big storms in France and Belgium this morning, spoiling the day for me so far as the high cloud is spilling across the Channel to leave us with a very hazy sky. 19C and very muggy when I left the house at 6am but with no sun the temp has only made it to 21C so far

R0C · 09-06-2014 12:21pm

Skies look promising at the moment in South Mayo again.

Several internet routers/phone lines hit in Kilmaine and Shrule yesterday evening during very intense lightning.

lolie · 09-06-2014 12:40pm

Looks like the west is the place to be again today.

dexter647 · 09-06-2014 1:04pm

Looking a little better tomorrow for us in the midlands:)

OldRio · 09-06-2014 1:10pm

Thunder, lightening and hail in South Leitrim at the moment.
