    Wind warnings in place for Sunday into Monday and again a fair spread in wind strengths, the GFS looks about in the middle

    The front crossing the country on Sunday afternoon looks very wet and windy followed by increasing wind strength along Atlantic coastal counties as the day goes on. Blustery over the country and gales along the coasts with strong onshore winds, looks like winds will increase towards night

    Some models showing it very windy overnight Sunday into Monday morning especially in the W and Ulster, models have been increasing these wind speeds over the last few runs. Wouldn't be surprised to see some Orange warnings perhaps in the W and NW.


    Met Eireann

    Status Yellow - Wind warning for Clare, Cork, Kerry, Limerick, Donegal, Connacht

    Met Éireann Weather Warning

    Very strong westerly winds are expected on Sunday and Monday. Coastal flooding is possible in places.

    The daily forecast here mentions winds 60-90kmph for Sunday, must be a mistake? GFS showing mean winds of 80-90 on the coast and inland a bit and gusts 110-120 quite a bit inland, looks a lot more severe than Eunice for all of Connacht and Donegal.

    ICON show gusts of 130 for my location but I presume Icon always overcooks this a bit?



  • Moderators, Science, Health & Environment Moderators Posts: 12,137 Mod ✭✭✭✭Meteorite58


    The GFS really surprising, a huge upgrade on previous runs, widespread Orange warnings, and high end in the NW at least, wouldn't take much to put it into a higher warning, rarely do you see the GFS the strongest of the models at this close to an event, usually the other way round, ARPEGE also looks strong, GFS looks as strong as the UKMO HD!

    Could be a named storm. This is the kind of scenario where people could be caught on the hop, deserves a thread.






  • Registered Users, Registered Users 2 Posts: 7,217 ✭✭✭pauldry


    I'd say Donegal 120 to 130

    Sligo 100 to 120

    Widespread 100kph elsewhere

    I have said it before and I'll say it again. Often the worst winds are a result of sneaky systems that while flagged can be worse for some compared to the ones with the name and all the media hype.



  • Registered Users, Registered Users 2 Posts: 10,222 ✭✭✭✭Oscar Bravo


    Make sure you take your mammys bloomers in off the line. Dont want them blowing into the neighbours lawn again .

    Donegal upgraded to ORANGE ALERT STATUS.


    Status Orange - Wind warning for Donegal

    Met Éireann Weather Warning

    Severe west to northwest winds with some damaging gusts are possible on Sunday night, please see yellow wind warning for Donegal where there is further details and associated risks.

    Thought it worth starting a thread for tomorrow into Monday, a lot of inclement weather going on ------> https://www.boards.ie/discussion/2058233823/strong-winds-wintry-and-potentially-stormy-later-sunday-20th-into-monday-21st-feb-2022#latest

    GFS 18z upgrading the cold slightly for next Thursday. We get very close to a direct northerly. If this verifies Thursday could be the coldest day of the winter so far.

    -9C uppers on Thursday.


    A near miss of a bitterly cold north-westerly from North-eastern Greenland.

    Without any mid Atlantic ridging or northern blocking, unfortunately this will just roll past us.

    So what are the thoughts on this 24 hour potential snow event? Uppers looking good and only 3 days out, will it be a downgrade closer to the time or will most of us get to see the white stuff??



  • Registered Users, Registered Users 2 Posts: 6,339 ✭✭✭highdef


    GFS seems to be only model supporting some lying snow on the past few runs and even at that, it's neither very much nor does it look like much, if anything, would be lying on lower ground below 100/150m except perhaps in the north. As it stands, I don't even think there's much there to downgrade in the first place.



  • Registered Users, Registered Users 2 Posts: 286 ✭✭almostthere12


    You're probably right but at least something to watch even if it is a few flakes like we got on Friday (Dublin 13)..........actually GEM is going for a bit more snow cover than it did for Eunice.

    I'll await Kermit's optimistic input!



  • Registered Users, Registered Users 2 Posts: 7,217 ✭✭✭pauldry


    It goes a bit too far North for widespread snow. Maybe the North and Northwest. Let's see what other runs bring. I think yesterday's storm may have cleared the direct jet a bit and maybe stormageddan is coming to an end bar Saturdays close call.



  • Moderators, Science, Health & Environment Moderators Posts: 12,137 Mod ✭✭✭✭Meteorite58



    To me looking like a cold wintry shower flow after the front clears on Weds, blustery day. After a lull away from the coasts Weds night giving widespread frosts inland into Thurs morning and then becoming quite blustery across the country and becoming very windy along the coast .Numerous wintry showers of rain, hail, sleet and snow showers moving well inland later Weds into Thurs, possible embedded troughs and thunderstorms quite possible. Cold day Thurs with added Windchill. Currently would think accumulations on hills and mountains it being so cold and maybe some lower down in places also but perhaps localized.

    Approaching milder air on Fri, looks a mainly day, some coastal showers, less clod Fri night /Sat morning. Lighter winds on Fri also.


    The W and NW coastal areas could see gusts up around 90 -100 km/h on Thurs, 70 - 80 km/h overland. Not as much precipitation as the last week but quite showery along Atlantic coastal counties Weds and Thurs.












  • Moderators, Science, Health & Environment Moderators Posts: 12,137 Mod ✭✭✭✭Meteorite58



    Cold airflow coming out of Canada and forming plenty of clouds on the way and reaching us as Weds goes on , 850 hPa winds.

    Bit of interest, real hit and miss stuff unless we get a trough going and who knows an area might get a few cm's.


    Thurs looks very cold getting up to no more that 6 or 7C in blustery conditions so a bite in the wind.








  • Registered Users, Registered Users 2 Posts: 3,025 ✭✭✭JanuarySnowstor


    Wednesday night is shaping up to see some widespread sleet and snow showers. Very cold uppers between midnight and 9am Thursday.

    It's a blink and miss it affair again but after this joke of a Winter it's notable!



  • Registered Users, Registered Users 2 Posts: 3,169 ✭✭✭Rebelbrowser


    Yeah, GFS still saying all the right things...




  • Registered Users, Registered Users 2 Posts: 3,169 ✭✭✭Rebelbrowser


    A bit of support from GEM too...

    This storm system has been edging further east on the latest GFS runs. Could impact the west next Sunday.

    Winter is more or less over now and it's time to move onto the Spring short range models.
