Heavy rain in Midlands and East this evening, risk of lightning

darkman2 · 10-07-2010 11:42am #1

Hi all,

Looks like some maybe very heavy rain for a time in some parts this evening with a risk of thunderstorms developing. Could lead to some spot flooding.

The Midlands and East look most at risk but most places will see heavy rain at times later today and overnight. The lot pushing North over night.

owenc · 10-07-2010 12:02pm

Yes the bbc show big massive green spots coming over me so maybe some thunder storms tonight, but that rain on the radar dosen't look too heavy. Lets hope so it would get rid of the boring weather.

Tom Cruises Left Nut · 10-07-2010 12:24pm

Any idea what time this is expected to clear ??

I don't wanna get saturated at Oxegen !

IrishHomer · 10-07-2010 12:40pm

It srianing very heavy here in Offaly for the past hour.

WOnder is this it that was due this evening? No sign of it easing looks like today is going to be a day for the bed here

maquiladora · 10-07-2010 1:00pm

Heavest rain will over the eastern half of the country this evening, roughly between 3 and 9 ish. Fairly good chance there will be some thunder mixed in there too. Horrible conditions for July.

Possible Thunder?!:):):):):):):):)

Met Eireann's 18Z aviation Significant Weather chart has some isolated embedded thunderstorms in an area covering all of the country. The only mention of thunderstorms for any of the TAFs for the 13 airports on the island is for Galway, from 15Z.

nacho libre · 10-07-2010 1:38pm

Bucketing down here now. If today's heavy rain isn't enough for you.
The good news is that next Tuesday and into Wednesday we should have an area of Low Pressure moving in right over us.

Strange its bone dry here and the radar shows again its missing us. seems really to be moving NE up from Cork/Kerry!

owenc · 10-07-2010 1:55pm

Its ment to be thundery around about 9pm here, i hope i get it like the time the electricity was cut out and it lasted 3 hours into the morning, it was worst ever thunderstorm in northern ireland i think.

Takeshi_Kovacs · 10-07-2010 2:17pm

We had some very heavy rain from around 11.30 to 13.30 today, but has since died off. No thundery storms either

CJWRC94 · 10-07-2010 2:23pm

Next Thursday looks to be the best day for convective activity this summer , we better just wait and hope GFS doesn't decide to change it's mind.:rolleyes:

Gonzo · 10-07-2010 2:23pm

in fairness i think the west of Ireland has seen only a fraction of the rain that the east has seen over the past 3 days, water levels must be back to normal here now.

Apparently the east has had the most rain but i haven't had much rain infact its dry again and last night was just drizzle again! I really want a thunderstorm!

Cherrycola · 10-07-2010 2:27pm

Been raining here in the Midlands since early afternoon, after a long day of rain yesterday too.

And i think i heard a rumble of thunder just now, but it could have been a truck passing!.

You mustn't have been around in 1985 then.

owenc · 10-07-2010 2:32pm

Not near you but there is some lightening strikes poping up on the south west coast of the island, lets hope that they cover the whole island by tonight!

Well maybe , lightning detectors have picked up a few strikes , but they all seem to well of the west coast , a good sign all the same , it will be later this evening the real thunder risk arrives and it will mainly the east/northeast aswell.

A kite with a key on the end, recreate an old experiment.

rain has started here, hope there is a storm tonight!

Well for you I'd advise this one: http://sproule.co.uk/weather/svlightning.html

Im going to mainly use this one: http://www.corklightning.com/

Might be good to see stuff coming from the south.

EDIT: Anybody in Clare seen anything , first strike onland according to that cork detector

Weather Warning

Issued at 10 July 2010 - 14:30
Updated Weather Alert for heavy rain.
The humid conditions will persist until late tonight and will give further heavy and thundery downpours in many areas.
Totals of 25 to 40 mm are expected.

snowstreams · 10-07-2010 4:42pm

I heard a rumble of thunder here in galway city there a while ago. It must have been that strike that was detected in Clare.

darkman2 · 10-07-2010 4:48pm

The frontal boundary is approaching the East coast now hitting that humid air on this side of the country. I suspect the radar will be igniting shortly...keep an eye out here.

http://www.metoffice.gov.uk/weather/uk/radar/

When you see the yellows, light pinks, and reds indicating heavy rain from now on chances are there will be thunder and lightning aswell. Also keep an eye off the South coast too. Some beefy echos in the last two hours.

Isn't that a bit presumptuous? There has been barely any sunshine and mostly overcast on the East Coast as well today as well and that was one of the indicators MT mentioned in his forecast last night. There just hasn't been the heating and convection needed for the spark you seem to be predicting. As well, the last GFS run changed where the majority of insatiability would be and it indicates more that the West/North Midlands will pick up the brunt of it into NI for this evening. Plus, it was mentioned that the primary hours for anything building would be 1500 to 1700 and only Galway and the West Midlands seems to have gotten anything like the GFS predicted.

Your forecasts are helpful, but you seem a bit overboard at times wishing for thunder (Not that thats a bad thing).

Hi,

Not presumptuous at all IMO. Embedded thundersorms are just as likely. We don't need sunshine hitting the ground to spark thunderstorms - with respect to MT (great forecaster that he is) that is a myth. All that is needed is humidity, a cold front, negative CAPE values and convenient collison of wind direction - squall lines and there is a very good chance of storms. You are partly right in that the siuation now is more condusive for land based convection which means that the more land traversed the greater the potential but it is not all land convection which has to be taken into account aswell.

The latest GFS run is the same as the previous one 6 hours ago for the next 12hrs. Only minor alterations but nothing significant really.

Also I did'nt say there will be thunderstorms btw - just that there is a good chance in certain areas. That's all anyone can say.

Lumi · 10-07-2010 5:47pm

Actually. you were spot on darkman2. There's been a fairly impressive thunderstorm in Moycullen in the last hour

djhaxman · 10-07-2010 6:08pm

Chucking it down in a big way here in Castleblayney, still no light show though.

M.T. Cranium · 10-07-2010 6:44pm

Would agree there is a slight risk of a severe storm in central to eastern Ireland this evening. Factors are all rather marginal for severe weather but conducive for thunder and lightning (the counties now most likely to see further lightning would be generally east of a line from Lough Neagh to Athlone to Waterford, and if anything marginally severe develops I would say look for that around Laois, Carlow and Kildare.)

If this system had been a little more dynamic and forced clearing (and greater heating) in the warm sector then we might have been seeing a squall line developing, and certainly some factors at play are marginally conducive for that, for example there is a fairly well-defined wind shear aloft, the central low pressure continues to deepen, albeit rather moderately, and the front is now approaching an area with better lift. So anyway, I imagine we will get half a dozen or more reports of thunder out of this from scattered locations as far north as possibly Down or Louth, and there is probably about a ten per cent chance of a marginally severe cell developing in the area outlined or nearby (not sure what Irish criteria for severe storms are, I am used to gusts to 100 km/hr, frequent lightning, hail greater than 2 cm, or rainfall of 25 mm an hour, the latter being possible here even if nothing else develops). As for a tornado which I saw being discussed somewhere, this situation does not look very conducive but you can't rule out a weak rope-style tornado if one of these cells made it to the limits I just outlined.

Anyway, I am keeping an eye on the radar here until about 8 p.m. at least, and the lightning detection sites.

.

Assume you meant positive CAPE?

Newbie here, moved to Dublin about 3 months ago but spent June out of Ireland with work and holiday and therefore missed the good weather !! One thing I've noticed - and today is a prime example - is how much more humid it is here compared to London. Dublin Airport was reporting 18c with a dewpoint of 17c earlier, very humid !

Plenty of localised flooding here in North Tipp, is that the worst of it over?

Im afraid this isnt confined to the midlands and east as the thread title suggests . Very heavy floods here in Donegal, and its very dark.
The BBC radar got it spot on , showing some of the heaviest downpours would be in the northwest.
This is the heaviest rain of the year so far.

Same though its slowing down now, it'll be gone at about 11/ 11.30. Imagine the rivers in the morning, the last time this happened my river (and any other river in this area.) overflowed near me and filled all the fields up to the top (but it was only about four fields). EDIT: guess what! Them ones over in england are getting thunder and lightening after getting that weather, i can't believe that, first they get a heatwave and now they steal our thunderstorms!:mad:

Winds picking up here over the last hour, WNW 30 - 40+km/h.

Heavy rain in Midlands and East this evening, risk of lightning
