Today's rain

squonk

'Rain, heavy and possibly thundery in places, with fog on hills and coasts. The rain will become largely confined to eastern areas during the day, with a clearance to sunny spells and scattered showers elsewhere. Breezy, with highest temperatures of 17 C to 22 C.'.

Are ME talking about thunder showers here? the bulk of the rain has passed off now and looking at Sat24 it looks bright out to our west. Is there someting else going on I'm missing? I'd expect a sunny day with a few scattered showers now and a breeze.

It's to do with a developing wave Sqounk, which can back track a front quite dramatically. While Hirlam is downgrading the risk slightly today for this evening in the east, it still looks pretty potant, with the possibility of some persistant thundery bursts late into the night:






The balance between the high to the east and the low to the west is very very fine, and even a slight increase in pressure over the continental lowlands could be enough to push the heavier stuff much further inland; while a slight decline would keep it more to the east. One to watch I think.

Cheers DE! I thought we'd done with that front! makes sense!

According to Gerry on the radio, we can expect '25 to 30mm rain overnight with significantly higher figures to high ground near the east coast'.

With a respite in the morning, more rain to follow tomorrow afternoon.

Watch out guys! I suppose if we can't have thunderstorms, I do like torrential rain

Looks like a real deluge for the East overnight. Not expecting thunder but you never know. I think some localised flooding may occur.

Met er reckon there wil be thundery bursts in this overnite especially near the east coast. We wait and see!

nacho libre

It will be interesting to see the recorded rainfall out of this in the east.

mike65

Its pelting down here, could be some flooding I reckon.

Just raining away nicely here. Not as heavy as it was this morning so far. The wind has died down a bit too. Still, with the evenings getting shorter, it's like the first sign of winter really

17mm already? - Your not far off an inch of rain then. Below moderate but persistent rainfall here. Heavier pulses south of you according to radar. Might get the odd rumble of thunder.

nacho libre

Are you in Wexford?
It will take some doing to equal the 52mm that was recorded in Rosslare over one weekend in June!

darkman2

Starting to pick up in intensity here but still below moderate I would say. Persistent though.

Snowbie

7.6mm with RR at 2.5mm/hr. Not too heavy yet.

Danno

Steady but light rain here since 9.30pm. Stopped a few minutes ago. Could see clear blue sky to my west as the sun set until a short while ago.

patneve

really picked up in the last 5 mins in dalkey V. heavy now

19.8mm now

Been absolutely pissing it down here in Portlaoise for about the last hour, hour and a half. Has really started coming down in the last 20 minutes or so. Surprised there wasn't any flashes or bangs from it yet, it's got that real thundery feel to it.

Speaking of which, Danno, is there something up with your detector at the moment? It's currently showing a line of storms stretching northeast / southwest from the Irish Sea down into Tipp / Limerick roughly, which when you run the sequence all starts very quickly and pops up out of the blue. Snowbie's detector isn't showing anything of major significance like that so I'm guessing there's interference or you're playing around in the attic again with it or something like that, would I be right?

Danno

Interference there Aidan. I repositioned the reciever in the attic the other day and me thinks its too close to the motorised vent in the bathroom ceiling.

aidan_dunne

Fair enough, Danno, I suspected something was amiss alright. If we had a line of storms like that for real, you could be certain that this forum would be absolutely hopping with activity and reports!

Danno

The ones west of here were in fact correct strikes but in the wrong location. There is a storm out over the Atlantic, west of Kerry that is being picked up. However, signals are weak, there are alot of mountains between here and Kerry and that is why they are plotted in over Limerick-Tipp, if the storm was stronger it would plot more correctly. Funnily enough, sometimes storms that are closer can actually plot far away too! It's a lottery when there is weak lightning.

The mountains of Wales truely throw these two detectors off altogether! :P

squonk

Gone all quiet here now. Was absolutely bucking it down though a few minute ago. A proper thunder shower. From the radar we seem to be in a light patch but the heavy stuff will resume after a bit I think.

Danno

http://www.sat24.com/frame.php?html=view&country=gb <<< I tell you, the detectors are picking up on a mighty active storm some 180 miles off the Kerry coast! Look at the power showers out there! That's impressive detection - over 300 miles from me and 375 from Snowbie!

Snowbie

Had a 25mm/hr rain rate from that heavy one but rain just light now.
Heavier stuff in the south midlands.

Snowbie

Off topic also notice the N Italy storm bubbling up also.

Rain has gotten heavier again now.

Danno

Got a belt of that there for nearly an hour dumping nearly 10mm of rain. It appears to be clearing NEwards at the moment.

OT: Look at the clump WNW of Donegal and how the upper level shear is cutting the top off it!

A bit more complicated than that Dan. In laymans terms, the atmosphere is divided into layers A through to F. When the Sun sets the D layer is lost and what you get is ionospheric reflection bringing the strike that bit closer. Mtns do have an impact also aswell as the salt water. Future releases will make detection better as i was saying a few days back.:)

12.5mm since the first drop and 1mm since midnight.

Danno

Ah, forgot that part! I do remember reading it in the manual (you see, I do RTFM) when I got the kit, but slipped my mind. AFAIK the NexStorm setting is ticked to allow for night time ranging.

Locking this thread to save the confusion with thread title.
