Thunderstorm/Convective Watch - Spring/Summer 2012

Su Campu · 18-04-2012 6:51pm

I'm just back in Celbridge, some 3 hours after that thunderstorm. There are still piles of hail along the bases of the walls, etc, and I've just measured some surviving hail stones at up to 12 mm in diameter.

Here's the GFS forecast sounding for here at that time, showing decent SBCAPE and MLCAPE, and equilibrium temperature of below -35 °C - a good combination for hail and thunder.

Wild Bill · 18-04-2012 11:10pm

Hail to the north, anvils to east, twisters to the south and downpours to the west.

7mm of rain in a 7 hour snizzle of total meh here last night (under cover of darkness)

Someone here must be spraying the place with weather-repellant. :mad:

Iancar29 · 18-04-2012 11:35pm

VIDEO is 1gb ... gonna take awhile to upload! ha :rolleyes:

So heres my photos form the day . Once again ive been going mad about not having a car to get a great full view shot. But ye... cant wish for everything.

Best Mammatus display ive seen in in ages here..

Do you have a photo of a hailstone?
So I'd know what to look out for?

Some of the old folk here swear they saw one in June 1978......

Short Time lapse i shot Wednesday evening in Waterford City looking East. Plenty of shower activity plus a rainbow on view.

Likewise. It's like the weather's teasing me recently. The Cb today basically gave me the finger as it passed agonisingly around my place in Belfield.

Iancar29 · 19-04-2012 1:33am

My video from earlier. Plane reports being hit by the lightning strike which my camera just about picks up the thunder from 4 mins onwards.

Enjoy

DOCARCH · 19-04-2012 6:33am

Radar showing a band/trough of showers over the Irish Sea atm moving towards the east coast - should/might reach the coast maybe by 8.00 or 8.30.

Iancar29 · 19-04-2012 1:23pm

Some nice bubbling up action around the Atlone area.

lolie · 19-04-2012 1:36pm

Pic or 2 from yesterday.
Some big showers built up but broke up as they went overhead:mad:

Some nice convection in the evening in the distance over north meath.

Iancar29 · 19-04-2012 2:01pm

Sferics just south of Mullingar ... Anyone there?!

DOCARCH · 19-04-2012 2:09pm

Hopefully we don't get a repeat of yesterday with everything slipping south to the west of Dublin! :rolleyes: I am hoping showers building over Fermanagh have 'our' name on them!

Hal1 · 19-04-2012 2:09pm

Netweather picking up those seferics now. Hope there's more to come. http://www.netweather.tv/index.cgi?action=lightning;sess=

dexter647 · 19-04-2012 2:10pm

Some fantastic cloud structures here atm...Looks very promising:)

redsteveireland · 19-04-2012 2:21pm

I can't believe I have to go to work when things are getting interesting :mad:

mickger844posts · 19-04-2012 3:32pm

Great convection around today with Cumulonimbus clouds filling the skies in all directions. Just had a brief Hail shower but no thunder. That little bit of extra heat is helping with convection.

Iancar29 · 19-04-2012 3:41pm

Sferic over Waterford City... radar not picking up any strong echoes in that direction though

vicwatson · 19-04-2012 3:42pm

Mate just texted me one big belt of Thunder over Wexford Town about 10 mins ago, Sun out now !!

ninebeanrows · 19-04-2012 3:56pm

I think tomorrow is the day for storms in the south and east.

Some good CAPE tomorrow, be interested to see what the 12z shows

My initial thoughts would be some storms particularly in the southeast

Iancar29 · 19-04-2012 4:33pm

PLease say someone has a nice shot of that cell that produced numerous sferics over mullingar?!

lolie · 19-04-2012 5:03pm

Heard one big rumble from this shower as it passed an hour ago.

Lookin at how it grew on the radar i'm surprised i didnt hear more.

MiNdGaM3 · 19-04-2012 5:18pm

Still yet to catch any storms here in Cork. A few hail showers and some impressive towering clouds about. Caught a nice snap of a system moving past the east of the city about 2 hours ago.

Iancar29 · 19-04-2012 5:45pm

funny how similar the cells near me look so similar to yesterday ha

Could go thundery in the next half hour for those in the lucan region again

Elmer Blooker · 19-04-2012 5:47pm

wow!! fantastic cumulonimbus southwest, west and northwest of Dublin.
best I've seen so far this year.

we are looking at the same ones so ha

... im in finglas.

ninebeanrows · 19-04-2012 6:11pm

Greater Dublin region would have done well had these moved this far east 2 hours ago, but the heat is dying and the CBs will start decaying very soon.

Iancar29 · 19-04-2012 6:15pm

BOOM!

DOCARCH · 19-04-2012 6:36pm

I nearly gave up! Showers to my north - showers to my south - showers to my west but nothing here. :mad:

Finally showers have arrived! No thunder though (yet).

ninebeanrows · 19-04-2012 6:44pm

One or two cells breeding to my north and northwest.

thomasj · 19-04-2012 6:47pm

Hailstones reported in the Dublin 15 area although no thunder yet

ninebeanrows · 19-04-2012 6:50pm

blackius · 19-04-2012 6:56pm

3 loud thunderclaps here in Ark low in last 5 mins

blackius · 19-04-2012 7:01pm

Very large hail.
Could here it hitting roof of shed 200mtrs away before it hailed here :eek:

DOCARCH · 19-04-2012 7:04pm

Some people have all the luck. :mad:

Shower divided here with heaviest bits passing to the north and south of me!!! :rolleyes:

blackius · 19-04-2012 7:04pm

2 more claps

DOCARCH · 19-04-2012 7:11pm

Can see your little storm on radar - popped up out of nowhere - obviously Wicklow Mtn influence.

A few more showers still seem to be building to the NW of Dublin.

yeah its out to sea now rumbling but there's a trail of precip connected to it over lug following.
Its connected by a dark vein about 10 miles
wide.
More hail now from under the vein

jimmynokia · 19-04-2012 7:29pm

About time can we have some more please...

blackius · 19-04-2012 7:49pm

Cell off arklow is getting bigger and back building inland now...its gone into reverse and is returning lol

Looks similar on Radar grab to what the radar looked like for the waterspout the other morning.

Interesting shower to my north on radar.

Su Campu · 19-04-2012 8:04pm

I took a flight out over Co. Meath this evening and counted 5 separate showers in view at one stage. Airliners on frequency were requesting turns to avoid these showers. It was nice flying around and between them, a bit like walking in a forest with huge towering trees either side. Didn't have my camera with me so missed out on a nice photo opportunity. :mad:

Su Campu · 19-04-2012 8:41pm

A few sferics were picked up in Dublin and east Meath earlier. Glad I landed when I did! Nothing in the Dublin or Casement reports though.

That one to south Dublin is from the shower that escaped to the south of me earlier.

*shakes fist (at sky)*

Iancar29 · 19-04-2012 10:06pm

Where abouts do you take off from Su? ... did any of the anvils have overshooting tops from ur view?

This is what I felt like doing today. Absolutely zilch here apart from a few drops. The most annoying thing is my parents back in Meath have taken a battering over the last few days.

From Weston. I only went to 2,000 ft, around 500 ft below cloud base, so no chance of seeing any overshooting tops from that angle!!

Yes, tomorrow could be the best day of the week, especially in the south.
