    I have never seen hail like this in Galway on local radio they said the hail was ripping the leaves off trees on Lough Atalia, I drove under a bridge as I thought the car would be damaged by the hail along with other cars

    Nice big clap of thunder here just now.

    Edit: Thunder quite frequent now but core is off to SE.

    Same sky here, except it is to my SE. Thunder seems to have eased up.

    Looking at radar I'd say it missed us by a km or so

    Some big Congestus producing a couple of localized showers and could see a few CB's in the distance but no sparks here in Tralee. Great cloudscapes nonetheless. Good few sferics detected around Galway, from accounts I would think there was more lightning then what is shown on the chart.

    That storm went almost directly overhead here, about a dozen big flashes before it moved on.
    Missed the first few but a friend said one was the biggest flash he every saw overhead.
    No hail here just very heavy rain.
    Looking at the radar it's part of the same cell that passed over galway earlier.

    It kicked of just after 7o'clock here. Notice the bright echo over Oldcastle on the radar at 7.15.
    Lovely loud cracks overhead, almost impossible to not get wet trying to record it though.

    Just curious if anyone witnessed a fairly intense but short lightning storm (mostly sheet lightning) around 9.30 tonight around west cork. Four of us watched it for nearly 5 mins. We could hear very distant thunder but the sky was on fire with flashes 2 or 3a second. We didn't see any distinct lightning but the sky lighting up. Would be probably be west of Clonakilty. Nothing showing up on storm radar or blitzordnung.

    No lightning showing up on any of the radars as you pointed out. Rain just skirting by the coast, very little overland but some big showers off the coast all right especially around 21.00 but the set up is not very conducive for lightning tonight. Fireworks from a festival or party perhaps ?

    You can, but most of the risk tomorrow is over the Irish sea:

    Thunderstorm rain in the Shannon and Cork Airport forecasts from morning to early afternoon. Albeit at a 30% prob.


  • Moderators, Science, Health & Environment Moderators Posts: 11,851 Mod ✭✭✭✭Meteorite58


    Thinking there could be some sporadic thunderstorms sweeping down over the country Late Fri Night ,Early Sat Morning / Sat as the storm drags in cold air aloft over relatively warm SST's. Convergence , decent CAPE and Lapse Rates and good amounts of LLS DLS could assist in the formation of convective clouds possibly producing some thunderstorms.
