Thursday/Friday: Lightning Storms, Flash Flooding Event Thread

Little snowy old me

Met Eireann now calling it for Ulster and Connaught. I'm going to get on with my day. It's a non event for Dublin and the east coast. This is not doom and gloom, this is based on their forecast.

Exacly, thats my thinking on thunderstorms.
Expect nothing and anything is a bonus, he/she has started that crap in this thread already.

Here is the upper forcing (divergence, shown by the +) that will hopefully help cool upper levels and increase CAPE values later this afternoon and evening. There is a corresponding boost in vertical motion at 500 hPa (pink area in the Irish Sea), probably also aided by the Welsh terrain, but not so much over Ireland. Hopefully we'll see some action but I'd prefer to be seeing a lot more activity happening over Biscay now. The next few hours are key.

Some models, in fact most now delay storms with heavy rainfall to the early hours of the morning in the east but storms with little or no rainfall prior. This is not actually that unusual with a plume like this - you can have lightning flashing all round and literally no rain reaching the surface. The lightning would be particularly high in elevation but still packs a visual punch.

It's disconcerting at first but it's quite a show all the same.

The last example I can think of was some time in the late 90's but I can't remember the year because I was too young - maybe 97 something like this occurred in Dublin.

If anyone remembers let us know. It was spectacular and very memorable.

I remember it happening in 2000.

Maybe i'm way out on the year. The lightning was relentless - never seen anything like it before prior but very little rainfall.

Definitely something you'd remember.

I remember something like this in Shannon when I was younger, my Dad brought me up along the river, loads of lightening flashing above us in the clouds, but no rain or thunder. Would have been maybe late 80's or early 90's.

Was surreal at the time.

That's another thing I forgot to mention - no audible thunder - despite lightning every few seconds.

I’ve seen that in Florida countless times, but never here! Might it have something to do with strong winds aloft and being upwind from the cell??

I am getting a sicking headache with this mugginess I am working at home in the southern part of the house.

Yep seen it in Florida - known as an electrical storm if I’m not mistaken

I think the models at this stage are better dumped in favor of now casting on observations but Hirlam has most storms hugging the east coast and effecting Wicklow, Dublin, Meath, Louth, Wexford...as well as storms through the north midlands to the northwest.



The reality is this could develop a multitude of ways.

Banana Republic.

The storm recently in Waterford was something I never experienced before with hardly any thunder and the heft of the rain when it came was crazy plus added the Gardaí were running around our street in the heavier weather looking for someone following as n attempted break in, flashing lights and flashing skies Some kinda awesome

Well, just go and lie down for a while over in the west wing then.

This is unusual, you usually are very optimistic. In these situations thunderstorms can occur in places that they aren't necessarily forecasted to. Also with the east forecast to be sunny, with quite warm and humid conditions into this evening, this heating may well storm development later on. It maybe the case that you miss out on seeing lightning in your area, but i'd be confident you'll at least see some in the distance night sky.

Very warm and sticky in Galway with no wind, real headache weather

Warm and windy in North Co Dublin.

Wexford - home to thunderstorms and tornadoes.

And strawberries.

Dublin airport METAR reporting 20 degrees with a DP of 15 and 73% humidity - how people manage to live in warm/hot countries I don't know! :pac:

Anyone remember 2003 I think in October? Lightning/thunder started from morning and lasted well into the night.

Thanks nacho, that gives me a bit of hope for later so. Its certainly 'muggy' enough for activity later so we will see how things go.
