Thunderstorms

Ahh not a sausage in Galway. Dark clouds to the east and south most of the day but nothing coming over the city thanks to the south westerly.
Ohh well some other time perhaps.

Earlier Snowbie was saying it was quiet in the south. Indeed it has been all day and still is. Blue skies with a scattering of cumulus. Not a sign of rain all day. Still the same and not a rumble all day.

Absolutely p*****g down here in west Kildare with thunder every 5 minutes or so. No breeze to speak of to move it on could be around for a while.

Got that and we did have lightning and thunder but only one ferocious clatter.

Only when it passed did i here a faint rumble but that was obviously over you then.Good downpour though.

Could see the anvil on that from here and mighty impressive sight.

Storm just started here in Westmeath (Rochfortbridge). Very black sky and some nice thunder. Have no noticed any lightning yet. Looks like is coming from the Offaly direction.

Just reporting back on the earlier thunder "storm" (if you could even call it that! :rolleyes: ) in Portlaoise.

Just before 8 there was an almighty clap of thunder here, as I reported, and it had started to lash rain but it was still sunny to the north of the house here. It was only after I logged off and looked out the windows to the south and west that I saw the big, black sky that was producing the rain and thunder. We got another 4 or 5 big claps of thunder but that was about it, though it contined to lash rain for almost an hour or so. Not exactly what you'd call a "thunderstorm", as I said above.

I saw 3 flashes of intercloud/intracloud (I think it's called. Feel free to correct me! ) fork lightning almost directly overhead at one point so it was pretty close to here, maybe within half a mile perhaps. It was a weird thing to see, though, to have lightning flashing overhead, thunder crashing, rain pouring down....... and yet it was still sunny on the opposite side of the house! Come to think of it, I think I only ever saw something like that once before, about 17 or 18 years ago, where it was still sunny while there was a thunderstorm going. That one went on for a good few hours, though, as I remember compared to the few claps we got this evening.

Still a horrible looking sky to the north and west here right now, but I think that's just what we had earlier clearing away. The skies are clear to the south and east and that's roughly where the weather is coming towards us here so I think that's all the action were going to see in Portlaoise for the rest of the evening, unless something unusual springs up.

What we had earlier must have knocked out the Chorus somewhere along the way, though, 'cos I'm missing 'Prison Break'....... dammit! :mad:

aidan_dunne

Saruman, I wouldn't be surprised if what you're getting now is some of what we had about 2 hours ago. What we had earlier moved off to the north so it could well be that or maybe some other cells are springing up from that same clump of weather now, perhaps.

Pity Snowbie doesn't have his new detector yet so we could track all this stuff more accurately. Any more news for us regarding it yet, Snowbie?

Snowbie

It was shipped today.Prob wedensday/thursday ill get it.

Snowbie

Looks like Tristrame is experiencing a heavy shower already down there or close to him on radar

rc28

Raining heavily enough here even though there's nothing on the radar., lots of small grey cumulus around- no convection yet as they have no definition.

It's just west of me.
Blue skies here but just 2 miles inland from here the shower stretches from Gorey right up to avoca.It's very black and you can see the rain pouring out of it.It's heading due north so it's unlikely to even spill a drop here.
No thunder heard.

The areas under it will get a good drenching though as they have to wait for a 20 mile long shower to pass through.

Convection blaring already here with big puffy cumulus towering high.

Today is going to be a thundery day in east and watch out for tornadic activity;)

Looks to be showers starting to bubble up now anyway. Looking better than yesterday I think so far. Can't see a bit here. Based in an office with a tiny window in Clondalkin today.

Where are you based Weathercheck?

Unlike yesterday the Mt Leinster to wicklow mts area seems to be spawning showers.
That could indeed get interesting as the wind here has already swung south east so we are likely to have a convergence zone there.
I'll see them but with a strong sea breeze like there is now, they'd have to be massive to get any further to the coast and nearer to me than the one that just passed.

Sferics are highly likely by early afternoon going on this excelent chart

I've always had time for the short range (12-18hrs) GFS

Note how most of the cape and lift avoids wexford though.

I am in Portmarnock.

For 11am the clouds are really getting very high, today could be the best day for a proper TS for a long time, not often you see charts like that posted by Tristrame here in Dublin

Snowbie

Convection being going all morning since about 6am.Towers springing up and covering about 5 octas of the sky here.

Maybe in the more intense showers you might get the odd funnel forming from downdrafts but there is no shear or strong low level winds for anything else.

ninebeanrows

Some showers building, one just to my north and another to my southwest.

A few drops of rain too.

Washout

Clouds are EXTREMLY dark over leopardstown

aidan_dunne

Yep, the CBs are already starting to build over Laois. I reckon the midlands, east and south are quite possibly going to see some thundery action this afternoon and evening.

Tornadic (is "tornadic" even a proper word? ) activity, though? Surely that would be a bit of a stretch, wouldn't it?

Indeed some sea breezes may be beneficial

Snowbie

Nah,only aid in convection.Give some wind convergence or sea breeze convergence only.Need strong low level shear and strong upper winds and theres no upper stuff.Sea breeze might aid in a funnel but ill doubt it.

IANAL (hullaballoo's test a/c)

Thunder in Dublin atm.

Mobhi1

Heavy showers here in D8 for the last hour or so. Just now had a few rumbles of thunder.

squonk

Was just looking at the useful links at the top of this thread. Is there a major difference between nowCast and this site; http://www.meteorologica.info/freedata_lightning.htm.
I've used the meteorologica.info page for a while and found it good.

Snowbie

Well if sea breeze is doing anything to day its producing good convection over wicklow mtns.Some beefy showers going on there atm jut south of Dublin

squonk

Think I'm hearing a fumble here in Clondalkin. Very hard to hear though as lots of noise around and the rumbles seem faint. Dark cloud to my south.

Snowbie

Thunder getting going here,2 loud rumbles in quick succession.Havin heard thunder this early in a long time.

Edit:cape in the mid 800s by middle of the afternoon

squonk

Definitely a few rumbles out here now. Looks cloudy to the south and quite dark. Blue just beyond us heading towards Lucan.

Heard quite a bit of thunder here too from the shower train just west.
Yup tis is going to be very interesting for some of you.
I think I'll have to storm chase and it's ripe for that.
The sea breeze here is adding fuel to the storms just west and they're only a 10 minute drive away
