Convective/Thunderstorm Discussion Spring /Summer 2025

Some very high cloud tops have stayed south for the last 2 hours. This picture not the most impressive. Hopefully a move north east coming soon

Likely understating it if anything. There was new claps of thunder literally every 2 to 3 seconds as it passed close by here earlier.

Wow… I wondered was it really as bad (as good?!) as all that. thanks!

Development in the Celtic Sea - that probably has Waterford City as a target.

Amazing convection to my west, towards Lanesborough. Photos taken 90 seconds apart.

Yeah I have my beady eyes on those for Wexford later, although I'm not expecting much action this far east. We'll see.

Almost overhead, but moving away, near Ardagh in Longford.

The thunderstorm warning has been extended to 6am tomorrow morning for Connaught.

Hopefully there is some night time activity, there was no lightning visible at all earlier as the storm was elevated.

somebody probably checked the radar in glasnevin and saw the purple white pixels over north Mayo, and asked in a really low energy tone “ what about upgrading Mayo to orange ?? Yeah suppose, whatever…

Creepy looking sky

The way it seems to be done here in Germany by the Deutsche Wetterdienst (DWD) is that they issue a thunderstorm watch, and then issue the warnings as the thunderstorms occur.

They're notoriously difficult to forecast, and if you start issuing orange warnings and getting events cancelled in large areas, there's going to be war when 90% of that area doesn't get a thunderstorm.

Absolutely I couldn't agree more 💯 , very difficult to forecast, I think we may have to cover warnings by area instead of counties and also as you said Germany do issuing thunderstorm watches as well 😀

a classic postcast!

Mayo was the spot to be in today.
