Convective/Thunderstorm Discussion 2013/14

This caused some problems with Sky's main uplink centre near Southampton and several services were lost for a few minutes so it must have been seriously intense!

I'd say that left a mark .

Yeah the Met have gone all



What are we looking at later so? Much lightshow potential?

Iancar29

Not really , only lightning potential is gonna be along the south coast , will die out over land , but heavy rain moving NE yes.

Didn't realise the southwest was under a level 1.

Yep , Cork City is in the firing line ! , main concern would be potential flooding with the recent rainy days.

But Satellite still showing some activity so keep an eye out!

Rain,

Very heavy rain here at the moment, and a few strikes recorded recorded along the Cork/Waterford coast in the last hour.

sunbabe08

GRRR that system passed over cork, and nothing, just extremely heavy rain.

Heavy showers here in wicklow but some very dark clouds rolling in now

About to reach the South Dublin coast here, I can only see northwards where its clear light blue skies but its gone very dark from the south!

ninebeanrows

Interesting feature, didn't expect to see it on the radar with the beautiful morning!

redsteveireland

Looks like it has lost it's spark before reaching Dublin.

Iancar29

Just listening in on Dublin Airport ATC.... Pilots doing the usual asking for course changes due weather ...one saying " We would like to request a left turn , radar showing weather ahead , whats it like on the runway ? " ... ATC : " Eh yes , there looks to be a big black cloud out the window " ...

hahahhahaaha

No doubt they're a bit skittish after the United 757 got the cement mixer treatment on approach last weekend, Pilots talk!

Yeah, if you didnt hear it check this out http://abcnews.go.com/GMA/video/severe-turbulence-injures-united-airline-passengers-dublin-bound-20631549

Great to get the feed replayed on ABC news.

Level one for Ireland and the UK , for strong convective gusts and possible tornado.




... British Isles and surroundings ...

The frontal system of the next pronounced low-pressure system crosses the British Isles. A strongly sheared and helical flow is forecast to develop in a narrow belt ahead of the cold front due to a concentrated Southwesterly low-level jet (25-30 m/s at 850 hPa). With marginally unstable profiles and strong forcing, a shallow convective line is expected to cross Ireland around noon and most of the UK by midnight. Severe wind gusts are possible, and a few tornadoes are not ruled out in the case that more discrete convection can crystallize along segments of the line.
After a few hours of postfrontal subsidence, a new round of deeper and more vigorous convection will move onshore overnight with the next vorticity lobes. Deep-layer shear will then decrease due to a more equalized flow through the depth of the troposphere, but with a few hundred J/kg of CAPE over the relatively warm sea and a further tightening gradient at low levels, even ill-organized storms will be capable of producing severe wind gusts. Limited area models agree on the development of a comma over the Celtic Sea overnight, though the solutions are highly diverging with respect to its timing, intensity and path. Hence it was decided to stay with a high-end level 1, though there is a possibility of widespread severe wind gusts in Ireland, Wales and Cornwall very late in the forecast period, when the 850 hPa flow starts to exceed 30 m/s!


And heres the 2 culprits !

ninebeanrows

From my reading of the above, they were contemplating level 2 for our region!

pad199207

Will be interesting to see if the "vigourous convection" develops and moves onshore, probably be an Atlantic Coastal affair

Iancar29

Interesting back edge bands to it..

redsteveireland

Some big gusts here now, rain has more or less stopped, waiting for those back edge bands to arrive.
