CAPE doesn't show much potential today.

Redsunset

tuesday afternoon looks juicy for the west if this chart holds up till then.

Redsunset

met eireann outlook seems promising for thundery downpours.there tuesday forecast seems to correspond with the cape and li chart above.



Clear/sunny spells and scattered showers for most places on Monday night and Tuesday, with the risk of some heavy or thundery showers (mainly daytime Tuesday) - however, the cloudy rainy weather may linger in parts of Ulster. Wednesday will bring showers or longer outbreaks of rain to most areas. Further heavy falls of rain on Thursday, mainly over the southern half of the country, with brighter showery conditions further north. Moderate to fresh southeast winds will gradually back northeast. Highest daytime temperatures will generally range 10 C to 14 C.

Mr Benevolent

Finally! At least there's even a risk of something interesting happening!

Mr Benevolent

Hmmm, scratch yesterday. Estofex has issued a Level 2 warning for today. The east coast has a risk of thunderstorms.

Theres a big slodge of stuff now heading into a line from North wexford up through wicklow and into Dublin.
The rain is persistant here now but mainly light so far.
It's getting heavier though.

Looks like 2 potentially thundery trains have developed maybe 50 miles wide.
One of them is stretching from the Brest peninsula through the channel islands/SW England and feeding northwestwards towards the south coast.

That will feed the same areas that got it last night from the same source and still have it today ie from waterford westwards across much of cork,parts of kerry and Limerick.
Theres actually a big collection of storms over the English channel that will follow that trajectory and eventually affect those counties.

The other Train is coming out of North Wales and the firing line from that lot is East Ulster down south into Louth and possibly north Dublin.
At the moment, the storms moving out of Wales seem the most active so the likelyhood of thunder from louth northwards is high.

Those under both trains,though there will be lulls at times are going to see an awfull lot of rain in the next 12 to 18 hours.

I wonder will they have the legs...the English Channel storms look like heading west and certainly won't affect here but may clip the south east. Maybe some development coming out of Wales in the next few hours.

Looking at Stormvue, there seems to be serious action in the Irish Sea tracking NW.

Looks like there's a big one just off the Wexford/Wicklow coast, according to StormVue:

I could see it in the distance. Never seen anything like that before,

squonk

got woken by a seriously loud bang of thunder at 6AM this morning. Nothing more though. I was going to get up if I thought there'd be lightening to spot. Here's hoping for some more!

The Black Oil

Must have been the same clatter that woke me up, squonk. I don't think I've heard it that loud before...

squonk

Yeah, it sounded more like an explosion than a clatter of thunder. I live near the Belfast train line so my immediate thought was one of the trains got derailed or something! Mad!

The Black Oil

Aye, I thought the gang from Lost had crashed again.

shamwari

I heard nothing and I'm very disappointed! I did think that the sky had a very thundery look about it when I got up this morning.

squonk

I'm surprised you missed it Shamwari! It was pretty loud. Having said that, it was just one rumble and I probably heard it because I was half awake anyway, it just finished the job

Redsunset

serious convection over ireland central africa:(

Redsunset
