    mostly dry day here so far, the rain somehow has avoided us for most of the day, going all around us!

    Dublin A, Casement and Phoenix Park all 17c at the moment, quite remarkable considering many days in August struggled to reach that in the afternoon!


  • Closed Accounts Posts: 1,635 ✭✭✭loubian


    So was there a storm last night?


  • Registered Users Posts: 635 ✭✭✭Video


    Any sign of a prolonged high pressure? i'm getting sick of rain now


  • Closed Accounts Posts: 3,047 ✭✭✭Clonmel1000


    Spent the weekend in Co. Mayo. First ever visit. Rained practically the whole time, was in Achill yesterday the wind was ferocious


  • Registered Users Posts: 6,027 ✭✭✭Elmer Blooker


    Forget the "snow this winter" thread - it's still summer!
    A 20c in the Dublin area on Bank Holiday Monday? It depends on good sunshine of course. ME predicting 17c but in Fohn conditions you could add a few degrees maybe?

    Quite! BBQ weather (apart from the wind and rain)


  • Registered Users Posts: 6,027 ✭✭✭Elmer Blooker


    The northwest and west will have yet more rain and drizzle during Bank Holiday Monday but the rest of the country will be mainly dry. Winds will back southerly, moderate to fresh and cloud will tend to break in eastern areas as the day goes on. Very mild, highest temperatures 13 to 17 degrees.
    winds backing southerly and cloud breaking in eastern areas tomorrow- 16c at the moment, surely a 20c in fohn conditions tomorrow cannot be ruled out!
    I love it! Heating still OFF and saving the € !

    Hey now, what's this at 72 hours on the ECM?

  • Registered Users Posts: 12,778 ✭✭✭✭ninebeanrows


    @ MAQ, noticed a little kink in the flow on the GFS but didn't investigate further

    Certainly chance of some very strong winds for the east coast even without look at this at higher res.

    That could bring some 90km winds onto the east coast , problems in dublin could occur with high tide at 4pm!

    Heres the NAE's take on it..

    Actually puts a small patch 50-60 knot mean winds in the Irish Sea!

    Yes, looks to be about 30 m/s sustained in the Irish Sea on the ECM. A higher res model with more intervals would probably yield even stronger winds. Or maybe the ECM is overdoing it a bit. Needs careful watching though, that could be very nasty indeed.


  • Registered Users Posts: 11,134 ✭✭✭✭maquiladora


    Had a look at the ECM postage stamps. It's such a small and fast moving feature it's hard to get a proper impression from the lower res panels but it seems about half the members go for something at least similar to the operational at 72 hours.

    Definitely keeping a close eye on this.


  • Registered Users Posts: 12,778 ✭✭✭✭ninebeanrows


    Certainly something signalled on the lower res GFS with some very strong winds for eastern counties

    Yes, both old and new GFS show that secondary low. Not as severe on those models but I think the ECM handles these small intense lows better than the GFS. Will be interesting once it gets into HIRLAM/EURO4 range tomorrow.


  • Registered Users Posts: 5,068 ✭✭✭Iancar29


    00z Nae 12km res showing up to 60kt gusts in the Irish sea , probably not as bad as the ECM showed being closer to high tide , we still need to see the higher res runs later .

    Flooding could be an issue with the amount of rain already yesterday and more today before this band forecast on thursday. Warranting its own thread perhaps?

  • Registered Users Posts: 11,134 ✭✭✭✭maquiladora


    0Z ECM looks to be a bit weaker and further east. Really need the higher-res models with this feature since its so small and fast moving.


  • Registered Users Posts: 11,134 ✭✭✭✭maquiladora


    Here it is on the 06Z EURO4 at 48 hours, strengthening down around the Bay Of Biscay. Very small area of storm force winds at that point. Could prove a surprise for somewhere, maybe Wales, maybe the east coast here, depends on the track. Will have a better idea after the 12Z runs are out.

    Do the current weather conditions on the East coast warrant a thread? The UK met and met eireann have lots of live flood and rain warnings.


  • Registered Users Posts: 7,796 ✭✭✭Calibos


    Ah jaysus. What looks like a squall line in the radar rather than running across us in Bray and thus be short lived is actually tracking NW up the country like an arrow aimed through the beating heart of Bray :D

    12Z HIRLAM shows the secondary low sliding up the Irish Sea with the strongest winds reaching the UK coastal fringes rather than the East Coast here.

    12Z GFS has a very similar track, with the small windfield being felt on the UK coast rather than here. It then spins up another secondary low which crosses the south of the country later than night.

    Will have to see what the ECM and EURO4 do later. A complex wet and windy spell coming up...
