    Instability on Monday giving rise to widespread convective showers , some of hail perhaps and thunderstorms a possibility.

    Upper trough with very cold uppers, cool enough day probably only getting up around 10 or 12C, showery troughs passing over the country, sunny spells also aiding convection.

    Unstable airmass following the front overnight into tomorrow producing heavy convective and at times squally showers with some of hail and parameters there for a spread of isolated thunderstorms. Quite a fresh day with quick moving showers. Sunny spells but on the cool side especially away from southern and eastern coasts, quite a cold feeling day along the Atlantic seaboard counties. Thunderstorm activity might peak in the Eastern half of the country tomorrow afternoon but anywhere could get a storm I think.

    Convection growing and moving across the country , a few strikes earlier North of Tipperary.

    Heavy showers here in Kerry overnight and a few early this morning, good bright spells now and breezy. 10.6C

    Mammatus clouds over Delvin, Co Westmeath

    Couple of distant rumbles lucan

    Rumbles of thunder here in Kildare after Heavy Hail



  • Registered Users Posts: 3,409 ✭✭✭Trebor176


    Had four or five rumbles of thunder a few moments ago in Clondalkin followed by heavy rain/hail.

    It is brightening up again now.

    Finally some decent April showers, pics from Old Military Road in the Dublin Mountains and Tallaght.




  • Registered Users Posts: 9,922 ✭✭✭spookwoman


    No major Mammatus clouds here in Waterford. Two big thunderheads went over and dumped hail at Dunmore East

    Might be some lightning about. Meteologix registered in clare and Blitzortung has 2 in kerry east of Waterville and north west of sneem. both registered on Metwologix now



  • Moderators, Science, Health & Environment Moderators Posts: 11,868 Mod ✭✭✭✭Meteorite58


    Most of the lightning bypassed Ireland today.






  • Moderators, Science, Health & Environment Moderators Posts: 11,868 Mod ✭✭✭✭Meteorite58


    To me it would seem that there is subtle instability tomorrow from an upper rotating trough and cold upper pool moving in over the S and E of Ireland producing a level of vorticity along with light low level convergence zones and subtle differences in land and sea temperatures all giving rise to the chance of heavy convective showers' and the chance, if somewhat small, of isolated thunderstorms . Mountainous or hilly areas might aid lift and around Wicklow/ Dublin might be one such area but chances are on the Low side. Bit of interest nonetheless. Sometimes these slow moving systems can let big convection grow unheeded as in that they are given time to mature slowly without being knocked over by strong winds. No supercells but could get some nice tall convection.

    Met Eireann mentioning 'A fair amount of cloud tomorrow with the best of any sunny spells in the south of the country during the morning. Scattered outbreaks of showery rain over the northern half of the country will become widespread through the morning, turning heavy at times with the possibility of isolated thunderstorms leading to localised surface flooding'

    Plenty of areas of convergence being seen in several parts of the country today. I see on the met.ie site that there have been recent lightning strikes in the Irish Sea, SE of Dublin. Looking at the radar, there looks to be an area of fairly convective activity in south Dublin/North Wicklow despite some very low surface temperatures of about 6/7°

    Big black clouds building here in waterford. Glorious sun where it's clear.

    Certainly looks very like a tornado, would be great to know the location and time, might be a waterspout if there is a lake , sea or reservoir behind the hill??


    Edit: I see on Cork Beo it was taken from the outskirts of Ballincollig .



  • Registered Users Posts: 9,922 ✭✭✭spookwoman


    That's Templehill. It's looking north from near MP Crowley on the south side of Ballincollig. Carrigrohan road would be at the back of that hill.

    Well done , good investigative skills there spookwoman!

    Lad on facebook posted a picture under Carlow weathers video and he says he took it at 1.10

    Between this and the March 13th event on Barrack Street, Cork is Ireland's tornado alley it seems.



  • Registered Users Posts: 1,999 ✭✭✭mcburns07


    We had this one a few years back as well, interestingly all 3 happened very close to each other.





  • Registered Users Posts: 1,812 ✭✭✭.Donegal.


    That’s look very impressive for an Irish tornado. To me anyway.



  • Moderators, Science, Health & Environment Moderators Posts: 11,868 Mod ✭✭✭✭Meteorite58


    Early indications of convective conditions on Sunday as an upper negatively tilted trough with associated cold upper pool moves across the country coinciding with peak diurnal heating up around 17 or 18C, looks like a convergence zone along the Eastern coasts could help peak the chance of thunderstorms there as trough lines pass over but storms look like they could occur anywhere. Good sunny spells also helping convection. Some big heavy showers , possibly of hail too, heaviest probably in the Eastern half of the country in the afternoon. One to watch.




  • Moderators, Science, Health & Environment Moderators Posts: 11,868 Mod ✭✭✭✭Meteorite58


    Plenty of convection today too, heavy showers in places, a good test for tomorrow where the parameters are better. Decent CAPE, any sunny breaks would help greatly producing a few thunderstorms ⛈️

    Convection building, showing up well on Satellite.




  • Moderators, Home & Garden Moderators, Science, Health & Environment Moderators Posts: 17,773 Mod ✭✭✭✭DOCARCH


    Hefty looking showers around me in Greystones. Feeling very humid.



  • Moderators, Home & Garden Moderators, Science, Health & Environment Moderators Posts: 17,773 Mod ✭✭✭✭DOCARCH


    Hearing thunder in Greystones....I think.



  • Registered Users Posts: 9,922 ✭✭✭spookwoman


    Lightning registering at Enniskerry in Co Wicklow

    In the vicinity all right. some good temperatures and Dp's getting over 12C giving a better chance for surface based storms to form.
