    Mod Note

    This thread is for posting / discussing /analyzing charts up to T120 ( in the more reliable time frame) for Summer 2022.

    If your post does not specifically relate to the charts then it doesn't belong here off topic posts will be moved or deleted- please use the Spring Discussion thread for general chat.



    Spring has ended on an unsettled and chilly note after a mostly dry and warm Spring. How is the first week of Summer 2022 shaping up?

    The coming week will be unsettled at times but not overly wet. High pressure will try to ridge in over the weekend but flabby and slow moving areas of low pressure are spinning slowly from southern Greenland into the north Atlantic and heading towards Ireland at times. It is uncertain how much rain will fall over the coming week but currently it looks about 10 to 20mm. These low pressures will spoil any chance of decent ridging over us and keep us generally cloudy and showery at times, but some spells of sunshine also likely.

    Temperatures up to Friday will generally between 11 and 16C, cooler than average. Temperatures will warm up slightly over the weekend to more average values for the time of year, generally 14 to 18C.

    Saturday and Sunday may be the driest days of the week with only a few light showers across the south and south-west.

    The early part of next week a ridge will try to get going but a big area of low pressure looks to have Ireland's name on it and will roll in from off the Atlantic as we enter midweek.

    Temperatures on Monday and Tuesday around average generally 14 to 18C.

    Rainfall generally 10 to 20mm and possibly drier towards the south and south-west.

    Not a great start to summer but at least it should be a bit milder than the past week has been.

    Been a real head scratcher trying to keep up with the models changing from run to run over the last week. Very hard to get any consistent idea of how warm it is going to be but trend is decent enough for many over the weekend. With a slow pivoting shallow low with occluded fronts and short wave troughs like what is moving across and close to Ireland over the coming days and nearby Hp on the fringes very hard to pinpoint temps and rainfall. Cloud looks to be a feature with sunny spells, Temperatures should be decent enough for many especially if we get some decent breaks in the cloud. Maybe a squeeze in the isobars at times giving some stronger winds locally especially the E. The frontal rain never materialized for Monday, bit of a difference in the models for temperatures, all depends on cloud cover but could get from the mid to high teens and currently looks staying mostly dry with some scattered showers perhaps.

  • Moderators, Science, Health & Environment Moderators Posts: 16,785 Mod ✭✭✭✭Gonzo

    Little change in the forcast for the week ahead, it will remain largely unsettled.

    The cool weather over the past week will continue for most of us for another few days with this weekend being chilly in eastern and southern half of the country where temperatures will struggle to reach the low teens. it will be mildest in the far west and north-west of the country.

    Saturday will be very cool across the south with temperatures ranging 10 to 14C with temperatures 14 to 17C across the rest of the country. A few places like Shannon might make it to 18 or 19C.

    It will be mainly dry in the northern 2/3rds of the country with southern areas prone to scattered showers keeping things very cool there.

    Sunday will be a cooler day generally with temperatures 11 to 14C in many places and some heavy bursts of rain across the south, east and some midland areas.

    It will be warmer in the far west and north-west but could be cool at times there too if it remains cloudy with showers still possible in those areas.

    Monday and Tuesday should see a brief respite from the unsettled conditions as a ridge will settle things down until Tuesday evening and it may turn a little warmer with winds going into the south-west.

    Temperatures on Monday generally 16 to 19C, possibly 20C in the north-west.

    Tuesday could be the warmest day of the year so far with temperatures 19 to 20 or 21C across most of the country.

    Turning much more unsettled from Wednesday with a big area of low pressure just off our west coast will move slowly eastwards and bring cooler temperatures and plenty of rain into the second half of next week and possibly beyond.

    It is unclear how wet it could become next week with current estimates between 30 and 85mm of rainfall throughout next week. This may change as the models are struggling a bit with so many little and large areas of low pressure into the mix.

    Misery :(

  • Registered Users Posts: 1,240 ✭✭✭Sammy2012

    Any idea of the rain arrival time in the east of the country on Wednesday?

  • Moderators, Science, Health & Environment Moderators Posts: 16,785 Mod ✭✭✭✭Gonzo

    too far away to be in any way accurate, we will have a better idea by Monday/Tuesday.

    right now Monday and Tuesday are looking like the best days for dry weather in the east, but of course that could still change between now and then.

    God damnit! I'm heading to Noel Gallagher in St. Anne's Park on Sunday evening. I have 6 weather apps on my phone and they all show nothing but rain and pure misery for most of Sunday evening. Best get the poncho and wellies ready :-(

  • Moderators, Science, Health & Environment Moderators Posts: 11,915 Mod ✭✭✭✭Meteorite58

    The week becomes increasingly unsettled as we get near to the weekend, areas of LP getting mobile, Frontal rain later in the week and thundery looking with the charts currently showing LP's with cool upper air over us aiding instability. Models showing temps mid to high teens first half of the week and from Thurs getting a bit lower, some areas under the rain and cloud struggling to get up to the mid teens. Hard to know where will get the better temps, all depends on the track of the LP's.

    Models currently showing a wet and windy day on Thurs, remains to be seen how windy. Plenty of weather to follow over the weekend it would seem at this stage.

  • Moderators, Science, Health & Environment Moderators Posts: 11,915 Mod ✭✭✭✭Meteorite58

    Looking fairly wet on Tues, becoming windy late Tues into Weds morning and and a breezy / windy day on Weds with showers or longer spells of rain. Temps look decent for many on Tues and falling back a bit on Weds. Some CAPE available on Weds so a few big showers about ,will see if there is any chance of a bit of lightning.

  • Moderators, Science, Health & Environment Moderators Posts: 11,915 Mod ✭✭✭✭Meteorite58

    That time of the year again , the remnants of Tropical Storm Alex making for a track between Iceland and Scotland and then filling and slowing down . Currently and probably will stay well off the coast bringing some blustery and gusty winds in over Ireland Fri and Sat. Showery with some longer spells of rain in the W but totals at this stage don't look too much for now. Seeing temps into the high teens and even touching 20C or so in the Eastern half of the country away from windward coastal counties. Breezy and perhaps blustery on Atlantic coasts later Thursday

  • Moderators, Science, Health & Environment Moderators Posts: 11,915 Mod ✭✭✭✭Meteorite58

    Remnants of Alex out in the Atlantic, big wind field with showers streaming in on a fresh wind tomorrow and homegrown convection possibly producing some heavy localized showers and could have thunderstorms, wouldn't be surprised to hear of some hail showers. High teens to low 20's in the Eastern half of the country over the next couple of days, temps down a bit in windward coastal counties, again looks like plenty of sunny spells, Sunday showing little rainfall.

    Still a wide range of scenarios for Fridays heat potential. Arpege 12z looks good with mid 20s widely across the country away from north-western coasts and possibly high 20s across the south and south. This looks great but I feel this is an absolute best case scenario and probably won't verify.

    The GFS is downgrading the heat potential for Friday with cooler air taking over most parts by Friday afternoon with only traces of warmth left in the far east and south. Nowhere nearly as warm as the Arpege with temperatures generally 14 to 20C, maybe a shade higher in the south and south-east.

    Icon is similar to the Arpege with mid twenties away from the north-west.

    UKV very similar to Icon and Arpege

    edit: ECM similar to the above and GEM a bit more widespread with the warmth.

    A truly glorious day today across the entire country it seems with reports of blue skies and strong sunshine in what has been the first nationwide day of summer warmth and sunshine.

    A bit of a blip tomorrow with plenty of cloud cover and a few spots of drizzle but this should break up as the afternoon goes on, however sunshine amounts will be very limited compared to today. Temperatures generally 15 to 18C, perhaps a degree or so higher if there are any decent sunny spells towards evening.

    Wednesday should be a decent day with plenty of sunny spells and temperatures warming up to similar values to Monday. Temperatures generally 20 to 23C but cooler along coastal regions.

    Thursday again very similar but perhaps a touch warmer, up to 24C possible in places if there is decent amount of sunshine on offer. Make the most of the fine weather on Thursday because it won't last into the weekend.

    Friday will see a big change to much fresher and more unsettled conditions. A band of rain will cross the country early on Friday morning followed by blustery winds and showers. Temperatures 9 to 13C in eastern areas under that rain band and 12 to 16C elsewhere with clear spells and blusterly showers.

    So no outdoor activities for the stag I’m going to in Kerry! A few days for the high stool!

  • Moderators, Science, Health & Environment Moderators Posts: 16,785 Mod ✭✭✭✭Gonzo

    Weekend doens't look good at all and this includes those heading to the UK for the Glastonbury Festival. It will be nice there until Friday and then wet and windy for the weekend.

  • Moderators, Science, Health & Environment Moderators Posts: 16,785 Mod ✭✭✭✭Gonzo

    Tomorrow and Thursday are still on track to be decent with temperatures widely into the low 20s but the temperatures will depend on the sun making a decent appearance. The cloud cover never really broke today so remains to be seen how well we do for sunshine tomorrow. Thursday will probably be the best day for sunshine with mid twenties possible for a short time in the south-east.

    Friday may see that rainband a bit later than what was showing yesterday. Eastern areas may get a fine morning but the rain will get there during the afternoon and temperatures should be ok in the first half of Friday. Still doesn't really change the outlook for the weekend which is poor everywhere across Ireland and the UK.

  • Moderators, Science, Health & Environment Moderators Posts: 11,915 Mod ✭✭✭✭Meteorite58

    Yeah the weekend looking particularly unsettled for much of the country. LP forming and deepening over us leading to a lot of rainfall, charts below from the ECM showing the rainfall to Fri and then to Sun at 16.00, ECM leading the way in rainfall it must be said, going by those amounts and looking at the 24 hr hour predictions could easily lead to Yellow warnings in parts especially on top of the hard ground but the other models are showing somewhat less at this stage so it might moderate a bit yet. Variable winds, possibly fairly fresh along the coasts, might get a bit blustery in the eastern half of the country also depending on the track of the Low, some areas near the center will be relatively calm.

    Temps look about avg on Fri - mid to high teens in the East , cool Sat and currently looking like only getting up around the mid teens on Sun.

    Watching with interest the possibility of thunderstorms over the weekend especially Sunday, could lead to slow moving heavy convective showers , will see if the thunderstorm risk materializes.

  • Registered Users Posts: 2,022 ✭✭✭mcburns07

    Well needed now unfortunately. 2-3 days of proper rain followed by a return to settled conditions would be great!

  • Moderators, Science, Health & Environment Moderators Posts: 11,915 Mod ✭✭✭✭Meteorite58

    Without a doubt, the land and reservoirs need it. I dont mind once we get a few sparks 😀

    Yes - agreed, the only acceptable summer rain is thunderstorm rain.

  • Registered Users Posts: 2,275 ✭✭✭Cork2021

    When was the last time we had proper proper thunderstorms around the country? The last time I remember decent thunderstorm activity was in the late July 2017 in North Cork!

  • Registered Users Posts: 673 ✭✭✭US3

    I'm in North Cork too we had a decent thunderstorm in June 2020 and a very good one May 2018

  • Registered Users Posts: 2,022 ✭✭✭mcburns07

    We had a fantastic night of lightning in May 2018 that ended a dry spell, only to be followed by an even drier and warmer spell 😁 took a screenshot of the Met E radar that night as a reminder.

    Oct 2017 - July 2018 will be very difficult to beat for interesting / enjoyable weather in my neck of the woods East Cork.

  • Moderators, Science, Health & Environment Moderators Posts: 16,785 Mod ✭✭✭✭Gonzo

    Honesty for me here in Meath it was Summer of 1985. Nothing of note ever since other than some thundery showers and even those are rare as hens teeth.

    Cork and Waterford/Wexford coastal areas probably stand a better chance than anywhere else in the country to get a French or Welsh import, I know they've had a few opportunites over the past few years.

  • Registered Users Posts: 1,716 ✭✭✭mr.stonewall

    Last summer after the warm spell at the end of July . Serious blast of thunder at 4 in the day through a band in in the middle of the country. Nenagh to kilkenny

    2020 in mid may. Again during the day.

    2019 in July at night.

    I also remember July 2017 serious rain with that thunderstorm.

    We always get some, but it's heat, humidity and instability in the atmosphere that we need.

  • Registered Users Posts: 2,275 ✭✭✭Cork2021

    i missed the 2018 one was in lahinch on my own stag party!! Yes I remember June 2020! The rain with that thunderstorm was lethal!

    Great reading back over the few days and then the big one on the 23rd, an impressive event, hard to come by in Ireland.
