    ARPEGE looks quite strong on Friday across the country, some much needed rainfall will be welcome.

    we are now into a much cooler setup for today and tomorrow with gusty winds and some showers at times. By Sunday we will see ridging from the Azores High extend back up over the country and a return to warmer and more settled conditions.

    Sunday see's a boost in temperatures again, reaching high teens in many areas and possible 20 or 21C in a few eastern and southern areas, particularly in spells of sunshine. Sunday will overall be far more pleasant than today or tomorrow with very little rain anywhere.

    Monday may be a touch cooler with mid to high teens across many areas, 20C still possible in Dublin if we get lucky with the sunshine.

    arpegeuk-41-85-0.png?22-06

    The rest of the week may be slightly cooler, mid teens generally, maybe high teens at times during decent spells of sunshine. Mostly dry but there could be showers at times along western and northern coasts. It may become more unsettled overall from next Thursday as the Atlantic tries to have another go at breaking things down.

    next few days look mostly lovely and warm.

    Tomorrow sees mid to high teens across most parts, cooler along the west with cloud or rain at times. A generally more cloudy day than today everywhere, best chance of sunshine in the far east of the country with temperatures nudging 20C.

    arpegeuk-41-32-0.png?24-12

    Tuesday:
    A cloudy start for many places, cloud may persist all day in the north. Becoming sunnier especially in southern and eastern areas. A big improvement in the west with less in the way of cloud and rain compared to Monday. Temperatures high teens to low 20's.

    arpegeuk-41-57-0.png?24-13

    Wednesday:
    Mostly sunny and warm. Winds may start to develop more of an easterly source direction to them so that will cool things down along eastern coasts. Temperatures generally high teens to low 20's, chance of 24 or 25C in a few midland or western areas.

    arpegeuk-41-87-0.png?24-06

    Thursday:
    more of the same, mostly warm and sunny. Cool along southern coasts and along eastern coastal fringes. Temperatures generally 18 to 23C.

    Friday:
    cooler day on Friday with a chance of some showery conditions and less in the way of sunshine. Temperatures generally 16 to 20C.

    126-582UK.GIF?24-6

    Turns warmer again for Saturday and Sunday with low to mid 20's possible inland areas.

    Slow moving weak and dissipating fronts tomorrow coming in from the W

    Rainfall amounts small away from W coasts, cloudy day spreading E

    Some grand warm days coming up as Gonzo said, ECM 12Z just rolling out and confirming Weds and Thurs as the warmest with 25C possible on Thurs, warm nights too so might be a good time to change to the summer quilt !

    ECM showing +12C uppers possibly across Leinster on Friday with temperatures possibly 8 to 10C above normal in some parts of Leinster. Doubt this will happen but if it did we could get to 26 or even 27C on Friday in places if we have a light south-westerly coupled with bags of sunshine across Leinster.

    ECM possibly overdoing Friday's warmth


  • Moderators, Science, Health & Environment Moderators Posts: 11,735 Mod ✭✭✭✭Meteorite58


    ICON showing +10C 850 hPa temps, GFS not as warm and UKMO showing +10 to +12C , warmest over the S. Very promising for warmth .

    Thursday has the potential to be the warmest day of the year, temperatures 24 to 25C widely across the country including Dublin, could Phoenix Park and Oak Park get a 26C on Thursday....

    arpegeuk-41-86-0.png?25-06

    I think most of us missed out on temperatures above 24C throughout last summer, it was a very poor summer for high temperatures.

    ECM dial's back on the uppers for Friday as expected, stlll impressively warm with +11C uppers crossing the country.

    ECM has been showing LP nudge up to the W Coast now for a few runs on Fri, it has been showing a front moving slowly in from the W, current run shows its passage during peak diurnal heating with DP from about 12 to 15C. This could produce hefty thunderstorms if it came to pass but all depends as it is up against a blocking high which could keep it out altogether. Interesting set up, with all that heat around those few days if it did move in during the day time could produce big thunderstorms. Could even produce storms overnight also Thurs into Fri if that was the timing, there being so much heat and moisture in the atmosphere. One to watch.

    Aah Dont say that. I have hay down 1 hour ago. Are those thunderstorms likely in the west only or countrywide.

    The front might be very weak, it might come inland a bit along the Western side of the country, it could even stall just offshore or along the coasts. Uncertain atm, charts not consistent at this stage, ECM showing just moving inland from around late afternoon, GFS more staying off or along the coasts later Fri night early Sat morning.




    Met Eireann : Friday: Many areas dry, with bright spells, but rain will develop in Connacht and west Munster later, with the possibility of some heavy, thundery bursts. Warm, with maximum temperatures of 17 to 23 Celsius, coolest in southern and eastern coastal areas. Breezy, in moderate south to southeast winds, fresh to strong on Atlantic and eastern coasts.

    just taking a look at the GEM over the next week and looks to be staying warm till about the 2nd or 3rd of June. This charts are for midday each day so add on a degree or two to each of these.

    Wednesday see's the warm air arriving. Might be cool enough in the northern half of the country to begin with but the heat marching northwards as the day goes' on. A high of 23 or 24C in places, particularly in the southern half of the country.

    GEMOPUK12_48_5.png

    Thursday appears to be the warmest day of this week. Temperatures widely 22 to 25C, it's possible we may squeeze a 26C in places like Shannon, Tralee, Oak Park, Phoenix Park (If the sea breezes behalf) and possible Mt Dillon.

    GEMOPUK12_72_5.png

    Thursday night could be very uncomfortable for some, particularly in the west where night time values may struggle to get much below 18C.

    Friday may be slightly cooler, but still very warm, temperatures generally 20 to 22C, sea breezes could keep eastern and southern coasts several degree's cooler.

    GEMOPUK12_96_5.png

    Heat begins to build again on Saturday and less of an impact from coastal breezes. Temperatures 21 to 24C widely across the country.

    GEMOPUK12_120_5.png

    Sunday more of the same.

    GEMOPUK12_144_5.png

    Getting towards FI with this one, but the GEM brings the warmest day of the year on Monday, 23 to 26C possible in many areas, maybe a sneaky 27C.

    GEMOPUK12_168_5.png

    From Tuesday the heat drains away from the north but that is into FI territory.

    I think the GEM tends to overdo the heat so it could turn out to be a degree or two cooler than what the charts show (ie. probably closer to 25c than 26/27c), still very good for the time of year though and what will happen remains to be seen!


  • Moderators, Science, Health & Environment Moderators Posts: 16,636 Mod ✭✭✭✭Gonzo


    We are beginning to feel the start of the high pressure and humidity building today. Tomorrow is when the heat really starts to build, particularly over the southern half of the country with 23 and 24C possible in many areas.

    arpegeuk-41-27-0.png?26-17

    Thursday could be the warmest day of Spring, heat really building, 23 to 26C widely across the country, could we see a 27C at Shannon?
    arpegeuk-41-49-0.png?26-18

    Friday there is no let up, the heat goes on. Perhaps slightly cooler, 22 to 25C generally but cooler along southern coasts.

    arpegeuk-41-75-0.png?26-18

    Saturday, more of the same, 22 to 25C widely across the country.
    arpegeuk-41-99-0.png?26-18

    This heat may also bring some slight discomfort to some, particularly at night where temperatures may struggle to get below 17C at any point during Thursday and Friday nights.

    Met Eireann saying coastal drizzle from Friday possible along the West facing coasts let's hope it don't happen

    Interesting to see the front hold off or close to the coast, ECM still showing potential for thunderstorms but these if they happened might all be just off the coast or some straying onto the coast. Looks like a good area of convergence will develop along Atlantic coasts and as the front, albeit weak ,gets into a holding pattern could produce convection and sparks, me thinks anyway.

    Shear levels good off the coast.

    Next few days look continuing very warm and dry.

    Tomorrow may be a touch cooler than today, particularly in eastern and southern areas with more of a keen breeze in off the sea. Temperatures 21 to 23C generally, high teens along southern and eastern coasts.

    arpegeuk-41-33-0.png?30-12

    Monday looks warmer away from the east coast, temperatures 23 to 26C generally. A few western locations may get to 27C, high teens to about 20C along the eastern coast.

    arpegeuk-41-56-0.png?30-13

    Tuesday has the potential to be the hottest day of the year in eastern and southern areas as we lose that easterly, Temperatures of 26 or 27C is possible from Dublin to Cork if we can hold onto the high uppers for most of the afternoon and sunny conditions.

    Much cooler temperatures leaking into the north and west, temperatures may tumble as the cold air filters through, 11 to 15C in these parts with the colder air moving south-eastwards. The extreme south-east of the country may hang onto the warm temperatures right through the day.

    arpegeuk-41-85-0.png?30-06

    Wednesday will be noticeably cooler for all, temperatures generally 11 to 16C across the country.

    102-580UK.GIF?30-6

    Wednesday may also see some rain or showers, this still has to nailed down, it depends on how closeby the azores high ridge is along with the positioning of the northerly plunge. In Scotland it could be cold enough for some snow showers in the Scottish highlands if there is decent shower potential.

    Temperatures may stage a slight recovery on Thursday and Friday and we become dry and settled once again.

    That plunge of cool air mass will be a bit of a shock to the system all right Gonzo. Rain looks to spread down from the NW Tuesday evening hearlding the introduction of fresher weather.

    Thurs looks to struggle to get to the mid teens.

    Rainfall amounts barely enough to keep the dust down for many.

    next week's cold plunge is definitely looking a bit more intense and prolonged, possibly a full week of below average temperatures, could well be back lighting fires by the end of the week.This plunge looks like it's going to be a major feature of the weather over western Europe for the first week into the second week of June. If we can keep things mostly dry, it shouldn't be as miserable as the cold and wet of June last year.
