    MT mentioning the plume around the 26 /27th and potential storm producer for Ireland and sryanbruen discussing the heat potential into the UK. ECM also showing around Mon 24th for potential frontal rains / Thunderstorms as LP comes up against the warmer airmass, as does the GFS .

    Looks warm and sticky some of the time , possibly quite wet in places at times, but plenty of dry spells also. ECM going more N'ly at the end of the run , shows it warm for the first few days and cooler towards the end of the week. . An interesting week coming for weather watching and potential thunderstorms.

    Still a long way off and less than clear .

    It's looking like we wont have a few dry days together so. I have a question for Sryan. Physically speaking why was May so dry with the completely negative NAO. In comparison why was June so wet with the same negative NAO. I'm curious. Like to know.

    looks more like Ireland will miss out any real warmth or settled conditions, staying more unsettled with the Atlantic influence over us. Hopefully we may see temperatures north of 19C for once this June!


  • Registered Users Posts: 39 HelloMrSnowman


    Look at us all fiending for the possibility of a day or two of reasonably okay weather, when this time last year we were getting sick of looking at runs like the one attached. Nearly a year ago to the day.

    Supposedly there's some gremlins in the new GFS model. Do you think that's affecting the perception of the forecast while its being worked out?

    ECMWF this morning showing widespread big thunderstorms and heavy rains at times next week. Currently showing it beginning Sun night into Mon. Very early days but one to watch , looking at the charts the last couple of days makes me think next week currently has the look of possibly becoming a memorable collection of weather events .

    Yup looking at those runs it shows Ireland right in the firing line for some Severe Thunderstorms moving up from Biscay

    ECMWF also hanging on to the warmer airs to the end of the week. Proper cut off low enveloped in warm air. Also showing it much warmer than earlier runs, low 20's possibly nudging onto the mid 20's.

    Will have to see if the runs continue this trend.

    I was thinking something on a par with 1985 , were definitely over due.
    Charts will probably back track though...

    that's certainly true, Ireland rarely ever gets decent thunderstorms, the last ones here in Meath we're indeed back in 1985, since then we've had the odd thunderstorm, but only baby ones, nothing too major and certainly nothing like the wonderful fireworks that England enjoys at least once most summers.

    BBC's outlook for next week does look rather thundery for Dublin (which is very unusual), but temperatures expected to peak at 19C, compared to 28C over England. Hopefully it will be a bit warmer than 19C, we seem to be stuck on that temperature max since April!


  • Moderators, Science, Health & Environment Moderators Posts: 16,702 Mod ✭✭✭✭Gonzo


    ensembles for Dublin showing a significant rise in temperatures for the Dublin area and loads of precipitation next week.

    ens_image.php?geoid=64981&var=201&run=6&date=2019-06-19&model=gfs&member=ENS&bw=

    Temperatures ramping up from a cool 0C @850hpa to possibly +20C @850hpa on some of the outlying members.
    These certainly seem a bit extreme for Dublin, if there was sunny spells this would result in temperatures north of 25C on the ground in about a weeks time. Overall the last week of June does look significantly warmer than the first 3 weeks of June where temperatures should comfortably reach 20C or more.

    I remember during January and February, it was always over delivering on snow potential for us with the operational run much more conservative and accurate. If this holds could be troublesum for us this winter!

    Indeed. The GFS operational run has continued to churn out these ludicrously warm charts yesterday evening and today again, generally not QUITE GFS 06z levels from yesterday thankfully but still ridiculous enough.

    Until something is done with this GFS, don't think I'll be looking at it or using it as a guide for forecasts rather something to have a laugh at. It's like the NAVGEM's long lost brother.

    Despite the anomalous -NAO in May, there was lots of ridging from Iberia (and some ridges from the Greenland High too) which influenced our weather. The Atlantic was blocked off from pushing through for the most part. May could have been an even colder and wetter month if we didn't have that ridging as central Europe had quite a cold May. There was one part of the month which was indicative of the June pattern we've had though and that was around the 8th/9th. The first chart was typical of May 2019 with high pressure ridging through us but its centre was to the northwest so was not warm whilst troughing was over Scandinavia and central Europe. The second chart from 8 May 2019 was more indicative of June.

    ECMWF there with the warm temperatures on the 12Z run again for next week , into the 20's and perhaps touching the mid 20's in places around Tues/ Weds, probably less warm Thurs and Fri but still in the high teens.

    With the cut off low positioned where it is we will have to see what type of moisture it brings up over us from the S, SE and E directions and what potential there is for thunderstorm development .

    in all my time looking at the thunderstorm risk charts on the GFS iv never seen such a high chance of activity over Ireland. So rare to see the bright red/orange/yellow shadings over Ireland. Is nobody remotely excited? Met Eireann also highlighting the risk of some thunderstorms as early as sunday night. 25 degrees at midnight in Ireland !? i think the gfs has gone mad.

    The 25°c is the maximum temperature between 9pm and midnight iirc.

    Still, interesting weather afoot. I will be watching developments with interest.


  • Closed Accounts Posts: 1,539 ✭✭✭The Specialist


    I’ll take the temperatures no problem but anything other than dry sunny days with those can **** right off, enough of it this summer.


  • Registered Users Posts: 584 ✭✭✭aisling86


    Trying not to get too excited I reckon it will end up being quite localised rather than widespread but hopefully I'll see some of it!


  • Registered Users Posts: 6,872 ✭✭✭pauldry


    Itl be 22c in Malin Head at midnight I predict

    But Sligo prob 17c by day and 21c by night

    This Summer is just a sick joke.

    12c now n its midsummers day tomorrow


  • Registered Users Posts: 13,498 ✭✭✭✭sryanbruen


    Looks like the ECM has joined the GFS in really turning up the furnace, somehow even warmer than the GFS OP this evening. Very sticky, humid air!

    All the main models now aligned for intense heat in southern uk, the heat also transfers more westwards on the latest ECM which would bring an increase in temperatures here.


  • Moderators, Science, Health & Environment Moderators Posts: 11,804 Mod ✭✭✭✭Meteorite58


    The ECM has certainly being bringing up the temperatures over the last few runs , going by the 12Z run we could be seeing temps getting up around :

    Tues... 24C
    Weds... 25C
    Thurs... 26C
    Fri... 26C
    Sat... 24C

    Could be seeing some dense fog at times next week and sea fog.

    Dew Points getting up around 18C next weds to 20C Thu

    Will see nearer the time precipitation forecasts and potential for thunderstorms.

    A fancy way of saying high humidity really.

    You will have the same people complaining it's too hot,that have been complaining it's been so cold...

    ECM 12Z rolling out .What a chart !

    Twice as warm 850hPa temps as the GFS.

    high 20's or over 30C if this came off.

    ECU0-144_vqv3.GIF

    Next one :eek:

    Maybe an outlier maybe not.

    A record breaker perhaps if it happened like this.

    Long way off and no doubt twists and turns to come.
