Thunder and lightning in Galway

Short but sweet display of lightning over the city - lovely stuff

And in the middle of the lightning the Coastguard helicopter from Sligo Rescue 118 was landing at Galway Hospital, great guys

Big blast of thunder here in Donegal followed by heavy hail shower

Large thunder and lightening storm (mostly sheet lightening lighting the whole sky) going on the past 30 minutes or so here, I watched it going up Lough Swilly from my bedroom window. Ended with an almighty hail shower just now.

Some very strong winds associated with a convective shower in the far north of the country in the past hour.

A gusty to 78mph was reported at Magilligan (Derry) and 67mph at Malin Head!!

Seen the flash from that, I think, circa 6.15pm? I saw the west sky light up from hilly ground in south Laois!

Yep was about then. Musta been it.

Pretty bad thunder directly overhead in Achill now. Hope we don't get a repeat of Christmas Eve 2013 when a lightening strike left the entire island without power.

And now we have torrential hail eek.

Rumbles of Thunder and Hailstones in Galway City at the moment

Nice convection going on today. Big showers of hail and sleet and good sunny spells, no thunder observed here in Ardfert.

Impressive hail shower in Oranmore at that time, nice mammatus off the back of it. No pics this time...

thunder, lightning and hail there a while ago in donegal

Meteorite58 · 24-12-2015 8:02pm

A lot of spherics in Donegal this evening and power out there in a few places.

redsteveireland · 25-12-2015 12:29am

There was a bad accident near J17 on the motorway as a result of that hail shower earlier today. The motorway was closed westbound for a while.

The low west of Ireland is the second focus, when its occlusion touches the west coast of Ireland between 19-23Z (GFS-12Z timing) and moves off to the north. 35 m/s deep layer shear and over 12 m/s 0-1 km would pass over western Ireland with steep mid level lapse rates overlapping the surface occlusion wrapped around the low. A band of high SREH is aligned with the occlusion. A field of 25 m/s mean low level winds surrounds the low. There is some chance of a tornado or convective severe wind gust.

What does that mean in lay mans terms?

Iancar29 · 27-12-2015 10:53pm

Chances of funnel clouds/ weak tornadoes and also strong gusts filtering down from higher levels.

Hal1 · 27-12-2015 10:55pm

It means there's a chance of a convective spell in that circled area. If you live in that approx area you should pack an umbrella tomorrow.

Oscar Bravo · 27-12-2015 10:56pm

Met eireann also going along them lines. "Strong and gusty southeast winds will moderate with the clearance, and become mainly southwest, but there is a risk of very strong and gusty westerly winds later in the afternoon on west coasts"

I do! Will an umbrella be enough?
