    A moisture laden secondary LP will move across Ireland during this evening
    and continue to push north early Sunday.

    The tight temperature gradient will enhance rainfall amounts and currently the GFS is predicting some big falls of rain countrywide, especially in the south west.

    Light rain will push into all areas during today and become progressively heavier towards morning with significant rainfall rates possible in some locations.

    Upto 80mm of rain is possible in Cork and Kerry and 50/60mm possible widely across the country.

    Raining lightly here for last half hour or so. Temp is a humid 19.2c
    Radar doesn't show much heavy rain at all.


  • Registered Users, Registered Users 2 Posts: 15,512 ✭✭✭✭Supercell


    16.3°C and 86% humidity here, loads of moisture in this air stream.
    Could be some big totals in places I think.
    Feels like a proper summer evening at last, shame it wasnt a month or two ago to enjoy the long evenings - Its an April sun, which is the last time it was nice!

    You got sun there this evening?
    Got wet here from about 6pm.

    Concur on the fear of the rain.
    Colder air coliding with the warm air mass should explode the rainfall :(

    Is the rain forecast to intensify because at the moment it's really nothing special, just light to moderate?

    Is it just me or has the 18z upped the rainfall intensity than what was shown on the 12z? There seems to be more purple over southern half of ireland?

    Quite wet here too but just persistant light stuff so far,the heavy stuff is still west of the East.
    Just restarted the main pc here,so live weather is back hopefully.

    The BBC 24 graphics now mirrors the 18z GFS in terms of the overnight rain and tomorrow - heaviest in munster-50mm's or more is highly likely.

    I'm a fan of the GFS within an 18 or 12hr frame,it's usually very accurate for then so I'm expecting a lot of rain... arrgh!

    The same describtion of what they are talking about on two is mentioned here on YT, a report from may of a sighting in bangor. There are no metor events forecasted for tonite, what make you think thats what it is?. Just heard this from radio5

    I have no idea what it is- I couldn't think of anything else but it has now been confirmed that it is not astronomical, ruling out meteors etc.That video you posted is very similar to what's being seen across England tonight, except there are more of them:

    Already have an impressive 20.1mm rain since midnight here. Looking at the radar looks like plenty more to come, going to break my daily record for sure.

    I wonder what totals are being recorded in the west and south west - been constantly under yellow and pink on the met éireann radar since yesterday afternoon.

    Thanks Mothman, must be a lot of flooding around the country given the sodden ground before this even started.
    The uk met office fax charts seem to be trying to develop a high late next week. Given the propensity of patterns locking in of late, here's hoping it pans out and gives us a late summer.

    Only 13.2mm here so far-consistent with that bit of East wexford and sout wicklow thats avoided most of the heavier rain
    Totally tipping it down now though

    currently 14mm/hr

    Tipping down since sometimes during the night

    Just persistent lightish stuff here.
    14.7mm


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    totals 4/5th to 10z

    Until the 1pm update from weatheronline, these figures are getting approximate. eg, Mullingar missed an hour earlier so I put in a guessimate for that hour.

    Rain is getting lighter after a few heavy bursts earlier on. It feels much cooler at 13.6c
    Ground is waterlogged again.


  • Closed Accounts Posts: 11,909 ✭✭✭✭Wertz


    Well dunno about the rest of you but the NE has seen persistant heavy rain for the last 15 hours or so...I don't have a weather station but I did leave a pot with brushes in it outside yesterday to soak....the pot has only been getting raindrops (nothing being channeled into it) and the water level is at least 1.5-2" higher than it was yesterday...maybe more.


  • Posts: 0 [Deleted User]


    21.1mm here so approaching an inch and we've been avoiding the heaviest of this.
    It was quite heavy between about 930 am and 11am.
    Presently it's wet but raining lightly and only just recordable Davis wise.


  • Registered Users, Registered Users 2 Posts: 15,512 ✭✭✭✭Supercell


    Still raining here, over 30mm today.

    Meanwhile London is at 27c and set to reach 30c, its also very sunny!


  • Registered Users, Registered Users 2 Posts: 9,235 ✭✭✭lucernarian


    I'd be about the same as Snowbie, just light (moderate once or twice) persistent rain. It looks much heavier 10 miles west of me though.

    The wind is increasingly coming from the north.

    By the looks of random containers and pots, there's been about 1 inch of rain or mabye a bit more since this rain started.

    Yes - 29.46mm here today so far. As usual, we are getting more than our colleagues at the coast...

  • Registered Users, Registered Users 2 Posts: 2,310 ✭✭✭Trogdor


    23.4mm so far here today, 25.7mm, just over an inch, since it started last night


  • Registered Users, Registered Users 2 Posts: 9,235 ✭✭✭lucernarian


    From the radar, it seems that it will get worse before it gets better, and if the rain holds its course, it will be another couple of hours before it stops here.

    yeah thats so annoying and always seems to happen! The rain which has fallen nationwide over past 15 hours has barely made much progress beyond the irish sea coastline and instead is being pushed ne into scotland, hard to believe that just 80 miles to our east is warm sunny conditions with hot weather further east again.


  • Closed Accounts Posts: 88,972 ✭✭✭✭mike65


    Sun is out here now - some of the time.

    Mike.


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    What is interesting today is the boundary of warmer,cooler air along with south/north wind

    This boundary has been moving back and forth across me. It got cooler about 7am, then warm at 8am for 30 minutes, then cool until 0930 and I'm still on the warm side.

    Trisitame 15 miles south has not seen the cool side at all. Longfield, 10 miles west cooled down at 7am as with me and warmed up at 0930 as with me, but didn't see the change at 8am. And I've just seen he's now on cool side.

    Trogdor, 15 miles north got the cool air at about 0530 and hasn't seen the warmer air since.

    EDIT, in the 5 minutes or so it took me to do this message, I see that I'm now on the cool side. The wind has swung 180deg and temp has dropped 1.5C

    Still south west down here-no sign of the northerly yet.

  • Registered Users, Registered Users 2 Posts: 4,347 ✭✭✭arctictree


    Yes, I now have a NW wind and temp down to 12.5.

    Earlier I had a temp of 15.2. Absolutely bucketing down now.

  • Registered Users, Registered Users 2 Posts: 9,235 ✭✭✭lucernarian


    I currently don't have a thermometer, but I do notice how the house is cooler now than when I got up at 9 am. I think the wind changed direction at about 10 or 10.30, I'm not sure really.

    http://www.nra.ie/RoadWeatherInfo/Map/data/htm/WeatherTable.htm

    I notice how Wexford is recording a southerly as at 1 pm. As is the Met station at Rosslare. And Arklow has southerly recorded, as indepently confirmed by Tristrame


  • Posts: 0 [Deleted User]


    Flat calm here now.
    Last known wind direction was West at 1mph as the dial tries to move from south west to North west presumably.

    Still very much in the "warm sector" here at 15.8c ( I refuse to call 15.8c warm)

    Complete turnaround in the weather here in last 20mins. A huge blue sky appeared out of the grey drizzle and now fills the entire western sky and the sun shining now with steam already rising from the rooftops and footpaths! Still grey to the east though. Fields have minor flooding and are muddy again.


  • Registered Users, Registered Users 2 Posts: 9,235 ✭✭✭lucernarian


    That was a bit trippy. As soon as I read rc8's post, the sky became much brighter here and there was bits of hazy blue to be seen. Though there's still drizzly rain here, the same for the last couple of hours. It still looks heavy out to the west, but the south looks quite dry.


  • Registered Users, Registered Users 2 Posts: 2,246 ✭✭✭rc28


    Completely cloudy again!:mad: :rolleyes:


  • Closed Accounts Posts: 6,498 ✭✭✭Mothman


    Arklow NW ;)

    Add the 3mm in the hour to 2pm to Casement's total.
    Dublin AP 1.4mm

    North west now but the temperature has gone up to 16.4c :confused:


  • Posts: 0 [Deleted User]


    It's dropped .3c since as you can see.

    I think most of the 1.5c rise happened under the calm conditions


  • Registered Users, Registered Users 2 Posts: 9,235 ✭✭✭lucernarian


    Stopped raining just after 2.30. Finally!
