    so we’re locked in to this pattern and I think it’s safe to say there’s no way out for the next few weeks, the St Swithin legend looks like getting it right this summer as it does I’d say 9 summers out of 10, it has nothing to do with that 40 rainy days nonsense, it’s generally about the pattern that prevails in mid July will continue into August.
    It really is a very interesting old weather lore that consistently gets it right.

    Is it just me or has the ECM performed terribly this summer? Along with most of the models. It predicted a ‘storm’ type system for today (Wednesday) at the weekend, never materialised. It predicted 16c and cloudy Monday when I was on Achill the day prior, it was closer to 22c and sunny. While we might be locked into a jet stream pattern, many of the GFS runs don’t seem as pessimistic. To me, the latest GFS run has some days next week looking decent while the ECM just has pure muck.

    Summer has been relatively dry for the most part up to this point, drizzle most days combined with wind and chilly temperatures but not much in actual rainfall amounts. Temperatures have warmed up back close to average but the weather is about to become more unsettled than what we've been used to this summer with much more in the way of rainfall totals. Next week may see another chilly spell as well, the third one of summer 2024 but this upcoming chilly spell is unlikely to be as prolonged as the last two were.

    GFS Ensemble graph shows things becoming wet from this weekend and this wet pattern continues right to the end with what looks like a very wet end to July and start to August. Temperatures sliding away again next week with chilly winds and possibly dartboard lows sliding across Ireland from the northwest. There is a warming trend as we begin August but that is quite far away and therefore is unreliable.

    Southern areas in particular look fairly wet on this particular GFS run with close to 100mm of rainfall possible over the next 2 weeks. This rainfall amount is likely to change from run to run.

    However it's worth noting that several times we have seen very wet ensemble graphs not verify with big rainfall totals and ended up with much dryer but still drizzely conditions so that could happen here yet again.

    Yes Wet Eireann has a washout Saturday but not much significant rain on other days here in Sligo bar the usual bits of mist n drizzle.



  • Registered Users, Registered Users 2 Posts: 3,422 ✭✭✭Dazler97


    Even if August is warm I'll be happy with that but I'm almost ready to give up on this summer ☀️ just imagine if we where the hotter side of the jet we'd be in 7 weeks of mid 20s

    A lot of heat building over Spain in the next week, I can see us getting an early August Heatwave with severe thunderstorms



  • Registered Users, Registered Users 2 Posts: 5,177 ✭✭✭Comhrá


    A few big thunderstorms, while not everyone's cup of tea, would at least give us weather enthusiasts something to look forward to in what must be one of the most boring summers in recent memory.



  • Registered Users, Registered Users 2 Posts: 198 ✭✭Hairypoppins


    No dart board lows/ chilly weather to arrive next week as far as I can see dis morning, Tuesday/ Wednesday/ Thursday actually looking quite nice coming in at around 21/22 degrees in sunshine



  • Moderators, Science, Health & Environment Moderators Posts: 17,429 Mod ✭✭✭✭Gonzo


    I think this is the 3th time this summer that the models showed alot of heavy precipitation with dart board lows across Ireland and it all fall apart in terms of rainfall (thankfully). The coming week will have some rainfall but nothing as wet as what was showing up just a few days ago. Warmer weather from the south could head our direction in about a weeks time will have to see about that.

    The latest EC46 extended forecast looks promising for August but as we know that model can be very unreliable more than a week out and changes it's output wildly from one run to another.



  • Registered Users, Registered Users 2 Posts: 662 ✭✭✭Robwindstorm


    I agree Gonzo. The models have been very poor all winter as well with huge swings every run. The inconsistency leaves the general forecasts from met eireann etc as unreliable, especially anything after 3 days. Anyway I suppose at least this topic is F1

    As said in the posts above low confidence in the models these days. A lot of movement in the weather patterns with the wavy Jet so hard to know if the charts below will verify, would get a couple of very warm days perhaps if they did. GFS not as good though ,neither is the GEM .

    The ECM still seems keen to bring in an area of high pressure towards the end of next week.

    The uppers aren't spectacular. But at this time of year any decent bit of sun will still see temps climb nicely into the low 20s at least.

    We could end up with a half-decent August after all.

    was hearing alot about warm settled weather the last 24 hours from next weekend onwards, that seemed to align with Mt craniums forecast this morning, but then i assumed that this would be in a southwest pig flow airstream, with drizzle, patchy rain and dampness along western coastal extremities of ireland with a permanent temperature of 15 degrees, with the warm hot weather for england and wales and a diluted version for ireland the further east you are. Im imaging if i were to look at the charts there would be a skinny elongated finger of the azores high tilted at a 45 degree angle creeping its way into southern england and then the pig flow on its northwestern flank smothering western ireland with the 10/15 degree 850 isotherm before its all pushed away in a few days and were back into the green slosh.So thats the S**t SHOW THAT WAS SUMMER 24 WRAPPED UP.

    The models have stuggled throughout summer so far, very unreliable more than 3 days out. The models have struggled with the cool north-westerly pattern becoming disrupted from either high pressure or a push of warmer air up from the south or south-east. The models have also struggled greatly with rainfall and low pressures. In reality we have had this strange dryish and cool summer that has been unsettled with light rain and drizzle most days.

    It's difficult to see where we go over the next 2 weeks but it does appear the warmer air will gradually make it's way towards us but it's a very slow process as the green churn of low pressures from the north are not giving up without a fight and the warmer, more settled conditions from the south is having great difficulty getting this far north. Overall I feel August will end up the warmest month of the summer which wouldn't be difficult based on how most of June and July has played out.

    On another note I feel we are in for a very warm September this year which could easily outclass June and July.



  • Registered Users, Registered Users 2 Posts: 1,707 ✭✭✭Billcarson


    I often think August and September can be opposites of each other. Many recent yrs we have seen poor August's followed by warm summerlike Septembers. August 2022 was among the better August's recently and was followed by a washout September. This yr I will not be surprised if August is the best month of this summer, which I know isn't saying much but could be one of the more better August's compared to many recently. Which if turns out to be the case might mean a more Autumnal type of September. Not very scientific but just my thoughts.



  • Registered Users, Registered Users 2 Posts: 781 ✭✭✭Timistry


    Its no good though in September. The days are much shorter and it can be chilly in the evenings. There have been very few evenings where you could sit out at 10 or 11 pm without feeling abit cold.



  • Registered Users, Registered Users 2 Posts: 3,186 ✭✭✭wazzzledazzle


    I've have known some January's Gonzo to outclass this June & July. Very low bar

    Looking at the ECM it does seem like temps are going to improve somewhat come the weekend although Saturday looks showery with Sunday being quite a nice day. Early signs for next week seem somewhat encouraging also.



  • Moderators, Science, Health & Environment Moderators Posts: 17,429 Mod ✭✭✭✭Gonzo


    Looks unsettled now right into August. Yesterday the models were looking hopeful for a warm and settled change into the final week of July but of course the rug has been pulled yet again by the models and the cool north-westerly regime we've been under since the final third of May is set to continue.

    yeah right now the models are about as reliable as a Bus Eireann timetable.



  • Registered Users, Registered Users 2 Posts: 3,422 ✭✭✭Dazler97


    What's current models looking like ? Surely there are signs of change and get us out of this stubborn pattern



  • Registered Users, Registered Users 2 Posts: 1,543 ✭✭✭esposito


    GFS 18z not bad actually. HP doing its best to get up over us. LP’s to our NW are stubborn af though.

  • Registered Users, Registered Users 2 Posts: 7,467 ✭✭✭pauldry


    Tonight and Wednesday morning were promised dry on Monday. Where did all this rain come from? Up to 82mm now. Currently the wettest month since April.



  • Registered Users, Registered Users 2 Posts: 3,422 ✭✭✭Dazler97


    Thats a start anyway , I'll take it with a pinch of salt but as long as it keeps going trend is looking positive anyway fingers and toes crossed



  • Registered Users, Registered Users 2 Posts: 6,054 ✭✭✭Storm 10


    According to ME "Becoming unsettled after Sunday as an Atlantic regime takes over" hopefully not



  • Registered Users, Registered Users 2 Posts: 7,467 ✭✭✭pauldry


    Yes ME who told us earlier in the week it would be settled from Sunday onwards Joanna Donnelly you know who I'm talking about.

    They should just say unsettled until December with an odd dry day and one or 2 storms and close ME until then. What is the point of ME when the weather has been in a rinse repeat for the past year.



  • Registered Users, Registered Users 2 Posts: 333 ✭✭ascophyllum


    Yikes, GFS is a horror show, a few days of ridging, then non stop low pressure out to the 9th August, its the same pattern since the 1st of June or so. Temps probably up a bit, but plenty of wind and rain likely.

    It feels like the same pattern since last September really, no sustained break in based on my anecdotal memory of the year (stats may prove me wrong on that).



  • Registered Users, Registered Users 2 Posts: 2,850 ✭✭✭.Donegal.


    GFS There’s not much rain at all for the next 10 days. 25mm(highest) for west Donegal and a couple of mm along the south coast.

    18Z rolling out now, not much rain over the next week or so, temperatures may rise a bit and then another flimsy attempt at high pressure towards the end which could be an outlier.
