Some isolated thundery downpours possible over the next couple of days giving some heavy localized rainfall.
IMO Weds at this stage looks like an active more widespread day for thunderstorms and more so over the Northern half of the country. As an upper low transits the country with associated troughs and quite a cold pool aloft with temps as low as -25C , quite low for this time of the year giving plenty of instability even though surface air temps are modest from the mid to high teens, highest in the S and E, NE . At this stage charts showing good lapse rates, LLS and DLS decent. Direction of flow from W to NE so would presume cells will be maturing whilst crossing the country giving some heavy downpours with risk of hail ( could be a decent size ). Could also have a chance of funnels and wouldn't rule out a report of a tornado or waterspout on the ground /over water, again more so in the Northern half of the country where Vorticity levels are at it's greatest, I think this is where the trough is more negatively tilted . Strong Jet over much of Ireland.
Could see CAPE values in the high hundreds of J/kg of even over 1000 j/kg, at it's highest in the afternoon.

Was just too dangerous to go outside the car with the constant thunder and flashes of lightning. Hail slightly melted but gives an idea of how big they were. On the far side of Carna the roads had about 1/2 a foot of water running over them like a river.
