    After two weeks of very unsettled charts from both the ECM and GEM, they are now building that Azores high over us after next weekend (this is what the GFS was showing up to last night).

    With the ECM and GEM both performing very well it does give a bit of encouragement of things warming up and settling down again. The GFS is now showing a very unsettled scene from next weekend with the Atlantic back in control so you have to wonder who could be right with this.

    The dissagreement between models continues.

    Yeah looks like frontal rain sometime around Fri and Saturday, will see. Looks like dragging in fairly warm humid air. Windy along Atlantic coastal counties for a time.

    We in north Offaly have got very little rain. We on our knees looking for it. We are considering selling half our herd off if no rain comes soon as we are already eating into our winter fodder supply and that is small enough

    What has any of this got to do with the weather forum. It seems like you think people on here can summon rain whenever they want. Maybe go over to an actual farming forum and look for solutions to the problem. It's funny looking at your previous posts- most are from the 2018 dry spell and you could have learned a few lessons from then and be more prepared for this type of weather now.

    There's very little you can do in preparation for a drought on a farm. You just couldn't store the quantities of water needed to in any way impact drought.

    Or if you had it the hours that would be needed to spread it on land.

    It's a problem related to weather and the gent in question is just looking for hope for his livelihood. On a forum where a pic of a lightning strike will get you 100 likes why does this draw such ire?

    I think a lot of urban people just don't understand it. A drought on farmland, with problems hydrating animals and crop growth, is, with all due respect, much more impactful on livelihood than someone's back garden in an estate turning brown.

    Tonights GEM is certainly looking interesting for warmth, some very warm possibilities.

    ens_image.php?geoid=64969&var=201&run=12&date=2020-06-14&model=gem&member=ENS&bw=1

    GEM isn't a model I normally rely on but over the past few weeks it has been fairly accurate, but not sure i'm buying the models very warm outlook just yet. Most runs stay around +6 to +8 but some runs go up to +16C.

    With the GEM max temperatures over the next 2 weeks are generally in the 18 to 23C range with temperatures up to 25 or 26C at times.

    gemeuw-9-240.png?12

    ECM also going for some very warm weather in about 10 days time with +13 uppers crossing the country.

    ECMOPEU12_240_2.png

    This would be enough to get us to the mid 20's, possibly high twenties in a few places.

    ECU100-240.GIF?14-0

    Health warnings definitely with these charts, we would need a consistent run from all models over the next week before I start believing in this build up of the Azores high after next weekend.

    Low pressure is just to out south now and the winds are very slack. My question is.. Why are the winds so slack with the LP just beneath us. Is it because we are close to its centre or something.

    Basically as you know the flow of the jet is west to east. During the autumn the polar vortex over north pole regions powers up which locks in deep cold high up over the polar regions. This big temperature difference between the polar regions and mid latitudes is what drives the jet stream during our winter and is one of the main reasons why our winters usually end in failure from a cold and snowy perspective. Our winter just gone had record breaking strong polar vortex along with record breaking positive AO and NAO, so we had relentless westerlies all through the winter resulting in a very wet autumn and winter. Northern blocking didn't stand a chance all winter because of this strength, but once the polar vortex began to weaken considerably in March (it usually starts decaying from March), we stood a better chance of northern blocking forming.

    Since March the jetstream weakened considerably, we've had plenty of northern blocking when we don't really want it. We've had mostly easterlys and northerly's since March which is why we have been very dry for the most part. When northern blocking happens, the jetstream still moves east to west, but the flow of the jet can get shifted away from us, it can dive south through the Atlantic and then flow west to east across southern Spain or Morocco. This places us on the cold side of the jet, the westerlies are cut off and we either get high pressure with winds in from the east, a northerly or low pressures moving north-east to south-west over us. We can also end up in no mans land with neither high pressure or low pressure and just fairly static conditions.

    We haven't really had the westerlies here since early March so high pressures have stuck around for ages. We have since had several northerly attacks and more recently a series of very slow moving low pressures moving north to south, these have become stuck over us in a very slack flow and this is why we've had a rather unfair distribution of showers or rain over the past few weeks with the east seeing most of any rain that's been going.

    Once we resume the westerlies we should go back to our typical pattern of bands of rain every few days on a constant conveyer belt. At the moment there is a bit of a battle between the Atlantic, the blocking over Scandinavia and the Azores high in the mid Atlantic. The low pressures over us are going nowhere fast because there is nothing to force them out of the way fairly quickly.

    It remains to be seen if the Atlantic will barge through over the next week. I think the Azores high will come back but we may have to wait till the end of June or sometime in July for that to happen.

    If we do get the westerlies back on steroids over the next few weeks then that could be a very worrying outcome for those of us who want a few weeks of warm and settled conditions during this summer. At the moment all we can do is wait and see what happens over the next few weeks. This battle is one of the reasons why the models have really struggled recently, the GFS in particular wants to bring the Azores high back to us every week but it has failed 2 or 3 times already with it's predictions.

    Azores back is the form horse, so I'd put much more faith in those charts than the ones showing Atlantic LPs coming back recently

    The building of the Azores high next week is once again beginning to look very much in doubt. It is on an absolute knifeedge with the low pressure brushing up against us just too close for comfort.

    The ECM has us warm on Sunday for a time on Monday before cooler air takes over.

    ECMOPEU12_144_1.png

    ECMOPEU12_240_1.png

    looks good for England but for us this is just too close for comfort.

    The GFS is even more unsettled with the low rolling in right over us bringing cool and wet weather.

    GFSOPEU12_156_1.png

    The low continues to rotate around us for days afterwards as well leading to an unsettled week next week.

    UKMO brushes the low very close to us as well so staying relatively cool and possibly unsettled with it too.

    UKMOPEU12_144_1.png

    GEM is similar with Ireland and Scotland on the cool and unsettled side.

    GEMOPEU12_168_1.png

    With the models changing every day I think we need another 2 or 3 days of model watching before we are sure where the low will go and how much of an affect will it have on our temperatures and the possibility of rain.

    Im so sorry. I know here in Kinsale, farmers are praying for rain too.
    We have been lucky and caught the odd shower, but a week of unsettled weather would relieve a lot of anxiety down here too.

    Honestly, this weather reminds me of the eighties when dad (and all the farmers locally) had to draw water from the creamery to keep the cows alive when the wells dried up.

    Don't mind anyone having a go at you, they have no idea. They forget, if we can't grow the food/feed the livestock, they don't eat.

    Hopefully the drought eases soon for you.


  • Registered Users Posts: 16,637 ✭✭✭✭nacho libre


    It look like we will stay on the cool and unsettled side in the early days of next week, as a low pressure hangs around near by preventing the Azores from ridging in. For the south east of England it looks to be a different story, some nice warm and sunny weather there.

    Unfortunately that looks like the likely scenario at this stage. Could get to the low 30s in parts of England and Wales next week, Ireland mid to high teens. There is still the possibility of some parts of Leinster tapping into some warm air temporarily if there are some sunny breaks.


  • Moderators, Science, Health & Environment Moderators Posts: 16,707 Mod ✭✭✭✭Gonzo


    How is the rest of June shaping up? It's beginning to look a bit clearer as June into early July will be fairly mixed. The low pressure currently sitting off our west coast looks like it's going to go nowhere fast over the next 1 to 2 weeks. It stays just off our western coast over the 5 to 6 days and then begins to move in again over us possibly next weekend and hangs around into the following week.

    This low will spend a considerable amount of time moving between Iceland and Ireland with unsettled conditions never too far away. The azores high will spend much of it's time just south and east of Ireland as the low is preventing it from having any proper affect on our weather.

    This almost looks like a rerun of July 2019 with the UK and most of Europe with very warm and possibly hot heatwave style conditions from that Azores while Ireland remains under the clutches of the Atlantic, however there will be a few days here and there where the Azores tries to extend in over the whole country but it doesn't look it will successfully do so at any stage this June.

    Ireland finds its self in no man's land for much of the time with eastern and southern parts dryer and slightly warmer and if sunny spells develop there could be some warm days with temperatures getting into the low twenties or even mid twenties at times. South-eastern areas most at risk from sunshine and higher temperatures.

    The west and north are closer to the areas of low pressure and may see bands of rain stall over the western coastal counties at times or showers. Even here there should be a few dry days most notably next Wednesday to Friday.

    To those looking for a prolonged dry and warm spell, you won't find it in this outlook, we may have to wait till July before we see sign's of this developing.

    Latest GFS run finds ourselves in a drying and warming trend for this week. Rain or showers is possible on Monday but it does turn dryer from Tuesday and upper temperatures at least start lifting up followed by a potential cool spell next weekend.

    show_diagrams.php?model=gfs&lid=ENS&var=201&bw=1&geoid=64981

    Wednesday continues with an area of low pressure south of Iceland that extends down past our western seaboard. The Azores is very close to us but not close enough. Some fairly warm uppers are over the country and we see signs that the country will dry out for a few days.

    GFSOPEU06_81_1.png

    GFSOPUK06_78_5.png

    Despite the warm uppers temperatures look fairly average high teens to low twenties, but there should be nice spells of sunshine.

    By next Friday it will remain dry across the country, mostly warm and sunny with low to mid twenties possible, particulary in south-eastern areas.

    GFSOPEU06_129_1.png

    GFSOPUK06_129_5.png

    Next Sunday see's cooler and more unsettled conditions once again take over the country from the west. This is basically the same area of low pressure that's over us currently.

    GFSOPEU06_177_1.png

    GFSOPUK06_174_5.png

    Temperatures low to mid teens at best, not helped by the band of rain from west to east.

    by Friday the 3rd of July this low pressure is still in our vacinity affecting the northern half of the country with bands of rain or showers.

    GFSOPEU06_288_1.png

    We finish on July 7th with a fairly typical zonal pattern for the summer, the Azores stays just to our south and we are in a flat westerly pattern with rain or showers at times mixed with the odd dryer and warmer day.

    GFSOPEU06_384_1.png

    Hopefully over the next week to 10 days we start to see serious signs of this Azores high extending it's influence over Ireland from July, after an unsettled June we are banking on July to quieten down and offer us a spell of summer.


  • Registered Users Posts: 282 ✭✭eon1208


    Met Eireanns latest forecast shows rain spreading across from the west Wednesday. They also give rain Friday and then say lots of dry weather over the weekend. A bit at odds with MTs forecast and the charts above. What do people think. Could this high come in ?? interesting stuff


  • Moderators, Science, Health & Environment Moderators Posts: 11,816 Mod ✭✭✭✭Meteorite58


    Bit of an Irish Summer forecast. Mixed. But if it was like this weekend alternating between rain from fronts passing over followed by bright fresh sunny weather I'll take it plus we dont run short of water. Looking warmer than average for most of the time out to +240hrs.

    Wednesday may see rain in the west, looks like it may get onshore and then nudge northwards through the north-west and then on to western Scotland. This rain doesn't look too heavy, light and patchy as the azores ridge will be through the east of the country. It doesn't look like there will be much if any rain in the south and east and possibly the midlands.

    From Thursday is where the models have disagreed and struggled a bit between the breakdown of the Azores ridge and another attack of the Atlantic through next weekend.

    Latest GFS looks very unsettled from next Friday with regular bouts of rain and showers throughout next weekend with cooler temperatures everywhere.

    Thursday could be quite warm with high uppers in place so there is a chance of a thundery breakdown on Thursday and into Friday.

    102-580UK.GIF?21-12

    The GEM delays the unsettled conditions to Saturday with possibly a very warm Friday in store.

    GEMOPUK12_120_5.png

    GEM brings the rain in from the west on Saturday and a very quick transition from high uppers to average uppers.

    ECM also going for a very warm Friday with high uppers through the country, could feel very muggy.

    ECMOPUK12_120_2.png

    ECM also brings the rain and much cooler air through on Saturday.

    The breakdown to cool Atlantic weather could start as early as Thursday evening or it may stay pushed back into Saturday or even Sunday. A few more days of model watching may be needed before we know for sure how next Friday and the weekend plays out.


  • Moderators, Science, Health & Environment Moderators Posts: 16,707 Mod ✭✭✭✭Gonzo


    tonight's GFS is really going to town with cool, windy and very unsettled weather next weekend and possibly beyond. GFS also has this breaking through the UK into other parts of north-western Europe suggesting that the jetstream may be about to get it's act together and the Atlantic powering up.

    Next Sunday looks very cool and windy with gales throughout the country and plenty of rain.

    GFSOPEU18_171_1.png

    GFSOPUK18_165_1.png

    GFSOPUK18_168_5.png

    Gusts up to 90km/h could be possible off the north-western coast and gusts inland between 50 and 70km/h.

    168-289UK.GIF?22-18

    Large rainfall totals by this time next week, much of this raining falling over next weekend.

    174-777UK.GIF?22-18

    Hopefully this gets downgraded somewhat, if this verifies it would be a very unpleasant and unseasonable spell of weather towards the end of June.

    Well once the UK is getting it aswell it isn’t as painful. Nothing worse with them just over there getting a heatwave while we drown.


  • Registered Users Posts: 282 ✭✭eon1208


    Bit of rain this past week everywhere was welcome for the land but we dont want it creeping into July. Be nice to see this low getting lost for a bit..


  • Registered Users Posts: 471 ✭✭KingdomRushed


    Once the levee breaks in an Irish summer it is very rare for it to reverse into good weather again. It was clear to me from the get go that this current pattern change was no short lived episode. Flabby low pressure systems over Ireland like this can and do hang around for months. The ones that don't are the rarity. By months end many people may see triple figure mm rain totals


  • Moderators, Science, Health & Environment Moderators Posts: 16,707 Mod ✭✭✭✭Gonzo


    It still remains to be seen how prolonged and how unsettled this pattern becomes. At the moment the last week of June and 1st week of July look increasingly unsettled not just across Ireland but also the UK, Scandinavia, the low countries, northern France and northern Germany. Definite signs that the Atlantic may dominate for a few weeks, that Azores high is going to have a tougher battle on it's hands.

    Most of the long term models are still going for a reasonably settled July, but the Beijing Climate Centre has changed their forecast to an unsettled July with westerlies dominating. It does however bring a more settled August.

    After the dry and settled spring I suppose it was always likely that there would be payback with an unsettled summer. It wouldn`t greatly surprise me if the weather stays cool with rain and showers all the way through to September.

    July could take some time to settle down but most long term models are hinting at a settled August and very settled Autumn. Certainly the short term models are becoming increasingly unsettled over the next few weeks. Once we get next weekend out of the way perhaps by then signs of it settling down again might appear in the short range models. The Azores will likely have several more attempts at trying to influence our weather but at the moment the Atlantic does appear to be regaining it's momentum with a clear zonal pattern in development for northern Europe.

    What I would like to see during July is the Scaninavian High rebuilding and the Azores high ridging over us and linking up with the high over the Nordic countries, sending the jetstream well to our north with lows not able to get anwhere near Ireland, a bit like June 2018.
