Absolutely lashing out of the heavens here in cork , haven't seen it this heavy in ages and hitting the north of the house which rarely happens. Could hear thunder off in the distance too! Windy aswell. Interesting night!

_Whimsical_

It's absolutely freezing in galway city, I've never heard thunder before when it's this cold.

Getting a bit of a light show here in South West Cork, a few flashes. Every 5-10 mins at the moment

Nice number of strikes off the south coast. Any chance they'll come north?

Was an active enough night in bantry, West cork. Currently have no electricity.

Meteorite58

Thunder storms tomorrow perhaps in the post frontal airmass as colder uppers are re introduced producing unstable conditions.

Meteorite58

Passage of troughs over the Southern half of the country tomorrow morning.

Day 2 Convective Outlook
VALID 06:00 UTC Sun 31 Dec 2017 - 05:59 UTC Mon 01 Jan 2018

ISSUED 22:05 UTC Sat 30 Dec 2017

ISSUED BY: Dan

Sharp upper trough will migrate eastwards across the British Isles on Sunday, with cold mid-levels atop SSTs generating deep instability in the post-frontal environment. The cold front first thing in the morning over England and Wales may exhibit some elements of line convection given strong flow parallel to the front in a strongly sheared environment. While this may be capable of a brief spell of gusty winds and heavy rain, in general convection will tend to be too shallow for much in the way of lightning.


Behind the cold front, several shortwaves will approach from the west, providing the focus for scattered showers that may occasionally form more organised lines as they track eastwards across Ireland, Wales and England. Lightning activity will tend to be most frequent over the Celtic Sea and English Channel, and adjacent coastal counties - a bit marginal for an upgrade to SLGT at present. Such deep convection will be capable of strong, gusty winds, small hail and perhaps a tornado.

Meteorite58

Looks like some squally showers ( some hail perhaps ) tomorrow and might be an impressive squall line heading across towards the UK in the afternoon, most of it perhaps offshore.

RoisinD

Flashes and thunder NW Clare.

Likewise in Galway city. Long low rumbles of thunder and a couple of lightning flashes out over the bay

Meteorite58

Plenty of big squally showers today here near Tralee nearly all with a mix of rain and hail. Impressive cloudscapes.

Plenty of activity over water but not much over land. Nice storm that moved into Galway / North Clare this morning.

A few recent sferics near the SW coast. Strike in Clare in the last 10 mins.

Further potential for thunderstorms / hail showers overnight and into tomorrow.

Seeing plenty of flashes here off the west cork coast! Only hearing a small bit of thunder though because I think the ocean is drowning out the sound. Beautiful though!
