I've done several of them and believe me, you'd never bother looking at another thunderstorm here in Ireland again after having a few Mid-West USA supercell experiences!0 -

That could be miles away, you don't stop operations everytime there's a thunderstorm in the vicinity.0 -

Interesting read here Wanderer78, according to this report air traffic was temporarily suspended although looking at flight tracker it would seem not for long. Large hail did enormous damage to crops in the area.

Bit of interest Tuesday for Thunderstorms, early days yet but worth keeping an eye on developments. Looking like a very warm day across large parts of the country.

Tuesday will start out dry with sunshine, however, the winds will become southeasterly in direction and the change in wind direction will bring a risk in the east of heavy showers in the afternoon and early evening. The fairer weather will continue in the west of the country where it will be warm once again.

Negatively-tilted Atlantic trough will slowly approach from the west on Tuesday - on its forward side, advection of a high WBPT airmass will occur from Biscay/France into southern Britain. This, combined with falling heights aloft, will aid destabilisation of the mid-levels through isentropic lift.
Given the lead time, there will undoubtedly be some uncertainty as to the exact forecast evolution (even on the day of the event, let alone some 4 days in advance!), but a broadbrush approach has been adopted for now to highlight some reasonable consistency amongst various NWP guidance. Upgrades to SLGT and perhaps MDT are likely as confidence improves nearer the time.
Current thinking is elevated thunderstorms will begin to develop on Tuesday afternoon over northern France / Channel Islands / English Channel, and then drift northwards in some fashion to S/SW Britain, continuing N or NE through the evening and overnight across portions of England and Wales, and perhaps the Republic of Ireland also. The exact track, coverage and timing rather uncertain at present, as one would expect - though several solutions keep the far SE largely storm-free, but very much subject to change depending on the phasing of the upper trough with the plume. Given the magnitude of CAPE and steep mid-level lapse rates, lightning will likely be frequent where thunderstorms occur.
Charts bound to change a bit but an idea f the potential.
At his stage rainfall expected in the afternoon / early evening.0 -

We can live in hope pad but I wouldn't dismiss them as too elevated yet or the fact they might stay in the Irish Sea
The last lot that took this route but stayed at sea,we could hear the distant booms in Arklow despite the lightning being mid sea
But yeah as weather nuts we'll take what we can get 0 -
