    Thought it might be an idea to put up a dedicated thread for what could become a very wet day especially across central counties.

    Possible that we might see thunderstorms also with very heavy local showers.

    No warnings in place as yet but the charts are showing some very high totals possibly leading to spot flooding especially after the heavy rain of the last couple of days.


    As the LP system moves off to the NW tomorrow we get an active frontal passage over the country which could produce a lot of rain, possible warning levels.

    Very little DLS but has LLS with a pronounced convergence zone especially across the center of the country, this could producing forcing along the front with thunderstorms a possibility.

    Cooler fresher air mass to follow the passage of the front.

    What the other models are predicting for Rainfall accumulations. Fairly common theme with highest totals across the center of the country.

    ICON which was off a bit the last dew days also looking similar to the other models .

    Latest AROME 18Z Showing some of the highest totals up until late tomorrow night ( will probably rain on after that too for a time ).

    MUCAPE would appear to peak there in the afternoon as well possibly bringing some thunderstorm activity. will see.

    Convective weather showing a slight risk for Northern Leinster into central counties.

    Day 2 Convective Outlook
    VALID 06:00 UTC Sat 10 Aug 2019 - 05:59 UTC Sun 11 Aug 2019

    ISSUED 20:01 UTC Fri 09 Aug 2019

    ISSUED BY: Dan

    A vertically-stacked low will drift slowly northeastwards across Scotland during Saturday, the associated cold pool creating an environment with marginally steep mid-level lapse rates, and 600-900 J/kg CAPE in response to diurnal heating. Assuming sufficient cloud breaks occur, scattered heavy showers and a few isolated thunderstorms may develop by the afternoon and early evening hours.

    Weak shear will result in "pulse type" convection, with slow storm motion bringing the risk of localised surface water flooding from prolonged downpours. This combined with fairly saturated profiles suggests the lightning potential is quite limited, and many areas within the SLGT will likely remain void of any lightning. A couple of funnel clouds will be possible as low-level vorticity gets stretched upwards by passing updrafts.

    Cloud cover is likely to be fairly extensive across Ireland courtesy of several occluded fronts - however, 500-700 J/kg CAPE could develop by the afternoon hours. Low-level convergence along and to the north of the frontal boundary could allow some heavy bursts of showery rain to develop, with some sporadic lightning - although given saturated profiles and weak shear, the coverage of lightning is rather uncertain.

    Something building off the galway coast on the satellite, alas no radar

    Torrential downpours last night. The noise was such it even woke me up . Looks like approx 39mm of rain fell in the 24 hours with the bulk of it over just three hours from midnight onwards.

    Interesting
    That is in line with the UKMO predictive sequence and met Éireann which has athenry in a relatively clear zone either side of very heavy shower trains

    Yr.no has us down for non stop deluge

    I know who I hope is correct

    Wind and rain in North Kerry this morning.

    Meteorite..how much rain have we had in the last few days?

    Wind and rain in North Kerry this morning.

    Meteorite..how much rain have we had in the last few days?

    Quite modest here compared to other parts, 21.4mm for the last 3 days and 28mm for the week and it looks like we are out of the main area of heavier rains today probably getting about 10 to 15mm.

    Windy with heavy mist and drizzle here near Tralee .

    4.6mm since midnight


  • Registered Users Posts: 1,685 Mobhi1


    There was only 0.6mm recorded here in Glasnevin overnight.

    Some of the model's rainfall accumulation predictions for today.

    Interesting that ECM has shifted it's heaviest rain more to an area around E Galway, Offaly , Weastmeath.

    Wasn't expecting much here today but these showers pushing through here now are very intense. Looks and feels Amazonian.

    Active thunderstorm at the moment in north county Dublin. Maybe in with a chance for us slightly further south nearer the city later.


  • Registered Users Posts: 25,241 ✭✭✭✭ HeidiHeidi


    Radar only now showing some rain moving into N Donegal, but it's been absolutely hammering down since about 10am (and probably before!)


  • Registered Users Posts: 6,030 ✭✭✭ Oneiric 3

    Heaviest of the rain only lasted just over an hour with just pointless dribbles since. Still, managed to grab 20mm + within that small timeframe.

    Nowhere near the scale of what Galway & Athenry experienced the other morning, but still, not bad.

    I don't have totals but there has been torrential rain in Cavan town since midday completely overwhelming the storm drains. No sign of it letting up either


  • Registered Users Posts: 6,675 ✭✭✭ ronnie3585


    Bucketing down in Galway city for the past hour or so, after a morning of heavy showers. There'll no doubt be flooding if this continues.


  • Registered Users Posts: 5,454 ✭✭✭ Storm 10


    Absoulatey torrential rain in Galway now floods all over the place was sure we would have sparks with this, roads in some parts pretty bad especially at the rear of UHG


  • Registered Users Posts: 15,692 ✭✭✭✭ zell12


    Seriously chucking down in Galway now

    Poor folk running the Streets Of Galway 8km later. There is 7mm of rain forecast between 7pm-9pm :(

    Edit: SNAP @ Storm10 & ronnie3585


  • Registered Users Posts: 2,816 ✭✭✭ redsteveireland


    No yellow warning for Galway... How?


  • Registered Users Posts: 37 ✭✭✭ CeeCeeBloom


    Absolutely manky day in Tallaght. Wind is fairly strong no heavy showers just persistent drizzly muck!

    Or Roscommon - current epicentre of that big orange radar blob.....
    No guage but I can confirm the Amazonian-ness as Oneiric says 😉
