Looks like the cover of a Led Zeppelin LP. (Though you're way to young to know that)

btw - 2.4mm of rain in a series of pathetic dribble-showers throughout the day here.

As usual

Here's a better pic of the mammatus I saw yesterday, taken from Donegal Weather Channel's facebook page. They were far more extensive than the pic shows but its a lot clearer than my own anyway

Looking at yesterday's rainfall totals

http://www.met.ie/latest/yesterday.asp

I am a little surprised to see that Casement only recorded 1.9mm for the entire day, especially given intensity of the showers in the region. Really shows how fickle and localised showers can be despite there apparent numeracy on radar returns. In the wider local area close to Casement 4.2mm was recorded at Phoenix Park, 8.2mm at Dub Airport and 12.1mm at Dunsany.

I am just 8 km from Casement as the crow flys and recorded 10.4 mm yesterday, 4.9 mm of which fell in 20 minutes with that "supercell" in the evening. I noticed all day that most of the showers passed just to my northwest, so I'm not surprised that Casement received less.

Also, Dun Laoghaire Harbour received 16.6 mm, so there again is proof of the localised nature.

Here's a map

How close in your expert opinions would yesterdays "supercell" have been to producing a tornado? What ingredients if any were missing?

A little sea convection and a little more heat to get the ball rolling earlier.

Indeed.

And I am located about 5km due west of Dun Laoghaire and we got virtually nothing today (2.4mm accumulated in spits and spots through the day).

I was in Glencree today (in the hills) and could see massive showers along the coast but the mountains were dry.

Edit: All depends on actual track (and timing) of low center passage, and even then, risk will always be very small for a few heavy showers to develop under the slack low on Thursday:


Assuming that prognosis, a good chance that the influence of the frontal occlusion will be to strong to allow anything worthy to develop and the GFS not showing much instability either with positive LIs' all round whilst the UKMO fax keeps the low center off shore. So after all that, and the fact that I have probably jinxed it there is about 10% chance of a thundery shower on Thursday developing somewhere. A non-existent risk, but a risk nonetheless:o

Large hail was reported , potential funnel cloud.. and rotation .... each in its own along with lightning can be classed then as a Severe thunderstorm. I like the idea of the Met Office with them saying " Supercell " over with the Oxfordshire cell so ye... our one is called the "Supercell " too k?!

Must have just missed it, they're on their way to the cell to the SW now. It looks impressive on Charles Edwards stream, definite hook forming on the latest doppler image

Can't be long until your tour now is it?

Tower FLYING up over the Dublin Mountains... Couldnt get a good shot of it though, not being lit up right for a good shot.

highdef

Very heavy hail shower passing over Inchicore. A lot of scud at the forward edge with a bit of rotation evident.

Rougies

Crazy hailstones, lightning and a clap of thunder here now.

EDIT: Another rumble of thunder further away, hail has stopped.
EDIT2: And another in the distance as it clears off. That's a very small but potent cell!

Elmer Blooker

A rumble to the south, over the city centre perhaps?

Twas looking nice. I was in Greenhills area, went to grab my phone to take a shot, left my phone in work.
The speed it built up at was scary.

Plenty of hail and a flash of lightining and then some of ye old thunder

Su Campu

ESTOFEX do have a 15% lightning chance over much of Ireland today

meemeep

small rumble over Sandyford just now. It's got very dark - bring it on!
