How much is a ridiculous amount?

Here's hoping for a very wet weekend before high pressure builds again next week as this memorable summer goes on.
The long range forecast on BBC News 24 at 2155 showed high pressure centred just to the NW of Ireland (similar to what we saw in June) so temperatures back into the high 20s in western areas again I would think.

I hope this high disappears for next week. Rain s needed v badly. We’re on verge of losing our livelihood with this drought as winter feed s next to nothing due to feeding it out. I so sick of 2018 wish it was over.

Oh dear, just when we are going on a well earned short staycation around the Barrow.

I hope it will not be a washout from Tuesday to Sat next week. Sad emoji....

But I do realise that rain is so needed. But NOT while I'm away please!

The organisers of the Bray Air Show must be in tears. To get that coming at you in a summer like this one.:(

The extent of rainfall has greatly reduced on the 0z run.

Good tweet here which highlights just how little impact the recent rainfalls have had on the drought:

It also reminds you that it's not about the reservoir levels being low, but the fact that their source rivers are drying up. That's what will cause our water supplies such long-range problems:

I wonder will the Shannon still flood this year if we get a spell of heavy rain.

Some nice prolonged rain in south Sligo. We have been pretty lucky with rain, amazing growth over the last few days.

Well for any fields that already had a bit of cover, bare ground will need a long time.

SleetAndSnow · 26-07-2018 4:09pm

Very heavy shower in cork city right now! Badly needed! First heavy rain since May 12th! Badly needed. The ground looks like autumn with all the leaves.

JJayoo · 26-07-2018 4:14pm

Raining very heavy for the last 30minutes in south Sligo, overflowing gutters on the shed

The_Outsider · 26-07-2018 4:47pm

That band of rain topped us off @ 44.2mm.
Bloody delighted to see it to be honest!
Happy plants now and hopefully a bit of pressure off the farmers here on the west coast.

Carry · 26-07-2018 4:49pm

I never thought that I would ever say that in Ireland, but I'm insanely happy that it is bucketing down here in East Clare.

:):)

270WIN · 26-07-2018 4:54pm

about an hour of light rain here in mid limerick,,gone now..land seriously parched..not enough rain at all

What about the thunderstorms on the night of 27th May?

JCX BXC · 26-07-2018 5:15pm

An immense amount of rain today from what I only expected to be 5mm at most, we got 21.8mm! West Clare.

Still raining at University of Limerick.

pauldry · 26-07-2018 9:54pm

Around 15mm of rain in Sligo

50mm by Sunday id say for North.

Hope theres a deep low Monday as they shove all the jet up North and more warmth results.

mickger844posts · 26-07-2018 10:28pm

Looks like thats it for us with just 4.3mm falling in Waterford City. Temp still a mild 17.8c but that will fall overnight.

uck51js9zml2yt · 26-07-2018 10:29pm

I'm in Donegal next week with the family on holidays. I want sunshine.

Last time we were there it rained so heavy for 3 days we couldn't get out of the car!
Don't mind if it rains until then..:)

JCX BXC · 26-07-2018 10:33pm

Further rain brought us to 25mm in West Clare. 5x what I was expecting.

Donegal Storm · 26-07-2018 11:02pm

Still dry in Maynooth, the front looks like its all but disintegrated at this stage so looks like we'll escape until tomorrow night

Gonzo · 26-07-2018 11:25pm

nothing here but a few spits of drizzle, not even wetting the ground properly.

KingdomRushed · 26-07-2018 11:40pm

Plenty more rain to come. Significant rain for some. Definite relief in store for agriculture anyway. Very heavy rain from a slow moving system Saturday night until Sunday lunch country wide

An hour of heavy drizzle in Wexford and that seems to be it. Still 18c outside and very muggy.

27-07-2018 7:53am

A heavy shower during the night in south Drogheda, that’s it , so dry out , hope we get more today .

Mobhi1 · 27-07-2018 8:05am

No rain here in Glasnevin overnight; a slight bit of drizzle this morning but the ground's not even damp. It's 18.2C and cloudy. There was even a little bit of sunshine peering through the clouds this morning.

27-07-2018 8:52am

We got a brief heavy shower in Kilkenny last night, - it was over before we knew it. That brings our entire rainfall for the month of July so far to 8.2mm. It's like Arizona here. Hoping for a good drenching this weekend because it is so badly needed.

km79 · 27-07-2018 9:46am

When yesterday's total is added in Athenry is only about 40 mm shy of the mean for July . Will probably end up around the mean after weekend

Carlow, Kilkenny, south Kildare, Wexford and east Waterford have really borne the brunt of this- absolutely scorched for weeks on end.

Donegal Storm · 27-07-2018 10:09am

Plenty more to come over the weekend for the south, July will be ending up wetter than average in places at this rate

South Sligo, got almost 2 inches in a few hours yesterday. Usually leave out a basin overnight just to see what the rain was like have never seen it fill so quickly.

pauldry · 27-07-2018 10:50am

Meanwhile the UK is set to hit 38c today

Does anyone have any links for live UK temperatures

UK Met Office used to have one but now all I find is a map

Like Met Eireann their old website was better in many ways

Just a quick calculation of how far below averages a small selection of stations around the country are (all figures for rainfall in mm, Data from Met Eireann):

Station | 30 Year Average | July so far | Differential | Driest July on Record
Cork Airport | 78.8 | 13.2 | -65.6 | 12.0
Shannon Airport | 65.9 | 22.5 | -43.4 | 12.6
Belmullet | 79.0 | 25.5 | -53.5 | 24.7
Malin Head | 76.8 | 44.3 | -32.5 | 16.5
Dublin Airport | 56.2 | 15.8 | -40.4 | 9.2
Casement | 54.2 | 9.0 | -45.2 | 8.6
Johnstown Castle (comparing with Rosslare for average) | 49.9 | 9.2 | -40.7 | 6.6
Valencia | 99.0 | 38.5 | -60.5 | 9.1
Mullingar | 61.8 | 18.2 | -43.6 | 14.8

If syranbruen has the driest July figures for these stations, I'd love to put them in the table too.

pauldry · 27-07-2018 10:54am

Huge Variation in Sligos rain yesterday

As mentioned above South Sligo had nearly 50mm in some areas
Markree only 6.5mm
Sligo town 20mm

You would need 100 weather stations in Co Sligo to get any consistency with our many micro climates!

Graces7 · 27-07-2018 11:35am

Loud heavy rain suddenly. A positive downpour!
Just beat it home as I was at the shore with the dog when a few drops started..

Lovely familiar drumming on the roof... ! Glorious!

West Mayo; offshore island

Mullingar|14.8|1983

I did Rosslare instead of Johnstown Castle.

Data comes from Met Éireann.

Oneiric 3 · 27-07-2018 11:51am

Here is a chart showing the 28 day running mean rainfall total for the nation as a whole (2018 data up to yesterday) I have included data from 1976 also to compare our current dry spell against:

What I found interesting about the infamous drought back in '76 is that it didn't really get going until late July into August, and by all accounts, proved to be quite severe, possibly more so than the current/recent spell.

What is also very interesting for me is how the exceptional dry spell back in late Summer '76 was followed by an extraordinarily wet one during the following Autumn.

Data and stuff from Met Éireann.

Netweather's current top 20 isn't a bad source. A 38c looks out of the question today.
