    Nice area of convergence along the South on Thurs where it should get into the low 20's but again weak shear and looks to be a strong cap in place, will see tomorrows charts .

    Mid level convection becoming more evidence here in a longford. Temperature is 25° so warmer than expected. Could things go boom later, perhaps? Arome is indicating heavy showers in many Midland areas, especially the northern half.

    A lot of cloud building now around Tralee, some convective in nature, don't know if it will spark though.

    I had an geography teacher years ago told me if I saw summery thundery clouds building, they had until about 3pm to do their thing otherwise no dice. In a non frontal situation, it's usually a correct assumption and I'd be surprised if we got sparks this evening. No disappointment though, lovely day and plenty of time in the seasons to come.

    Plenty of big bubbly clouds around but kind of hope they don’t pop. Such a lovely evening, don’t need a big shower unless it’s 🌩️

    Very dark large cloud forming in Galway Bay has a look of thunder about it

    I've over 200 pots and containers that are looking for water so I'm hoping there's a heavy shower in the coming hours as everything is currently watered via a big tank and a couple of watering cans.

    Someone’s getting a downpour

    Parameter's although marginal and a way less shear than would need normally could still produce thunderstorms tomorrow afternoon especially along the convergence line running along the inland south of the country. Places like the Galtees, Comeraghs, Knockmealdown, Blackstairs and Wicklow Mountain Ranges could aid lift and be an area of interest . The afternoon heat south of the Cold Front and subtle instability from converging winds and subtle movement aloft in the upper trough could give rise to some heavy convective showers and possibly thunderstorms.

    Skew T for Clonmel tomorrow afternoon,

    In excess of 100 strikes already in Cork



  • Registered Users, Registered Users 2 Posts: 2,905 ✭✭✭pureza


    is that storm not in Co Cork between Bantry and Drimoleague?

    posted this on the spring thread but I can see the convergence zone convection in south Leinster from here in Arklow

    Storm looks quite nasty alright anyone there that can report it for us

    How long did it last for ,it looked like over an hour on radar



  • Registered Users, Registered Users 2 Posts: 716 ✭✭✭StormForce13


    It would have taken over an hour to pass. Very slow moving, very local, not much rain, but quite a lot of thunder. Even in the middle of it, one could still see the sun shining on the nearby hills.

    Nice cell with good height around Bantry but the only one that formed and very little rain along the South in the end. Hard to get storms without decent shear in Ireland. Fair bit of activity over in the UK today.
