    @Danno - I'm curious as to why you use mph for wind speed.

    I grew up with using miles and continue with them as I'm familiar with them from the get go. Interestingly, I'd use metres in place of yards but would use feet also!

    It's complicated! :D

    Met Eireann's meteogram has gone a bit mad lately, showing thunderstorms for hours and hours, even for here:

    Not the first time they have showed this in recent days. Must be something to do with a change in an algorithm or something, but one that is highly misleading.

    I generally use knots for windspeed, though I am cool with MPH. Cannot comprehend Km/h to be honest, it makes little sense to me but that is something I am cool with as well.

    Just for interest, the Met Éireann aviation chart for 18Z shows the following details for the eastern half of Ireland covered by a slow-moving occlusion:

    Widespread 6 km, moderate rain/light rain & drizzle,
    Occasional 3 km, heavy rain/moderate rain drizzle/moderate thunderstorms
    Isolated fog/mist

    Tipping down rain in south Laois. Notably misty with the moderate rain. 2.4mm according to the AWS.

    Their app seems to be stuck on thunderstorms today for my part of the East but not a peep

    ME rainfall radar makes tomorrow and saturday look like winter storm levels of rain. How miserable.

    I'm guessing there's little to no chance of lightening or else the thread would be full of technical discussion and all those various maps people get from idk where.

    There won't be the hint of a spark anywhere.

    They now have pretty much the exact same thing in their 00Z chart too, except the area now covers everywhere except Kerry and West Cork. Seems like a bust forecase on both accounts.

    There must have been a spark somewhere as power gone in Mountmellick since 6pm. I heard a transformer pop and fizz. I was sure it was a firework being let off!

    Anyway, open fire, camping kettle, and a bit of patience and now I can hardly stay awake. Ate like a King, campfire coffee and now the steady drone of summer rain. Bliss!

    No power returning in Mountmellick now until 530am.
    Between Covid and this, the whole town is gone to bed since 1030 (observer excepted).

    More of a darkening today, very dull out there. Looking at the radar where I am in North Kildare, there could be persistent moderate rain for a few hours. When it eventually clears there will hopefully be some lightening. No chance of lightning though.

    I'm glad to see that since the recent thunderstorm activity and the resultant traffic on this thread, the incidence of lightening has declined quite a bit, and we're seeing much more lightning. The message is getting through. Now....if there was some way to get people to start spelling the word 'lose' without the extra o, it would be a wonderful thing! ;)

    Some people are too loose with their use of their primary language.

    Getting this back on track. No lightning yesterday but I have a friend who lives on the Black Sea coast and yesterday he contacted me for a weather forecast, they were under a level 1 from estofex. They had a lot of storms first half of the day yesterday.

    NOTE: This thread has gone waaay off topic. Please stop pulling people up on their spelling, it's not helpful to this type of forum.

    Thank You.

    In the post frontal air mass Sunday signs of potential for sporadic quick moving thunderstorms and heavy localized rainfall .

    Passage of a trough ( looks negatively tilted ) coinciding with peak diurnal heating. Good low level shear, Deep layer shear present but not as strong as later in the day on the current charts , decent lapse rates. Cold upper pool of air, DP's 12 or 13C.

    Looks like most activity in the Northern half of the country especially towards Northern counties.

    ECM Skew T near Dunshaughlin , for Gonzo !

    Very hit and miss I would think very hard to pinpoint.
