The latest report from Dublin Airport says that Cumulonimbus clouds have been observed which ain't a bad thing

Just saw this great live lightning website. you can enable audio so that there is a click every time a strike occurs......lots of clicks at the moment!!! A good few other very good features too:

That clump heading out from the north of Spain could have our name on it and might develop?

Very heavy rain here in North Tipp over the last hour. Had a flash of lightning and rumble of thunder circa 19.10.

Not really no as the warm temps and dew points around the channel are good enough to keep it going , and usually , once an MCS forms , it sustains itself for a few hours.

Possible that the remnants of the MCS will survive to produce at least some thunderstorm activity around 0600h to 0800h in south Leinster and Dublin. Will keep an eye on this overnight as for me it is late afternoon, and update around 0300h with an alert if required at that time. The heavy rainfall situation is already covered in our boards forecast although I was going to wait for the morning to issue an alert as it probably won't become too intense until mid-day and afternoon in the west.

the huge train of thunderstorms over Wales and the Irish Sea is the perfect dividing line between the UK Heatwave and the cold atlantic muck over Ireland, eastern Northern Ireland coastal locations should be on the fringe edge of much excitement through the night.

My comment just reminded me that this dividing line of fun was further west and much enhanced back in 1985 when we in eastern Ireland had a night to remember with an almost constant 24 hour thunderstorm! these things are very rare indeed. I was only 12 back then and we all moved to sleep in the Garage as we were afraid of our large BBC aerial being stuck my lightning and crashing through the roof, luckily that didn't happen, but instead we had hailstones are size of small oranges. wish I was older back then and not scared sh!tless!

Yesterday looked impressive on radar though the storms were quite fast moving and spread over a wide area so on reality most people probably only experienced half an hour of moderate thunder and lightning, certainly not something I'd turn down but probably not as dramatic as the radar suggested.

A couple of years ago there was a major outbreak in England producing something like 65000 strikes, that's what a proper plume can produce! Yesterday was only around 3000-4000 I think so nothing remotely close to what the 1985 storms would have been like

Short range model has heavy showers breaking out in the southeast around noon, spreading west as the afternoon goes on with some very heavy stuff in Munster.

looking at what that HI Res forecast for this morning in the east wouldn't fill one with confidence for later predictions!

Yeah. I might even get the grass cut. South west looks good for all the fun

Yeah i was 8 at the time, i remember it was very hot and sunny during the day so we hit the beach, when we got there we couldnt see anything due to fog, it was crazy, so we left and before we got home the thunder had started, it was terrific, myself and the auld boy spent most of the night standing at the back door watching it all happen, it really was a great night.

Good sunshine here at the moment... 16.3c with dewpoints a slutry 14.1c. Perfect fuel for the fire later!

Yep. Cells just off the coast from Pembroke heading northwest too.
