    Should be some sparks along Atlantic coastal counties later tonight as heavy showers move in ,spreading to other areas tomorrow as a cold unstable and strengthening westerly airflow with gales developes overnight and into Wednesday. Active troughs will follow also.

    As mentioned above some of the airports forecasting thunderstorms tomorrow ,Knock being one example

    Looks like a good convective set up all right, should be plenty of hail showers ,maybe a few sparks.

    GR is hail, GS is Grauple.

    Also, I don't see any deterioration imminent, are you referring to the TEMPO 4000? Nothing about wind or precip.


  • Moderators, Science, Health & Environment Moderators Posts: 11,766 Mod ✭✭✭✭Meteorite58


    Getting lively again

    Surely most winter time hail is GS? I'd say it always reported as GS over here just like when have you ever seen SNRA in a taf? Always RASN

    I know GS is normally graupel or "soft hail", but I note that Met Éireann always seem to use it for hail instead of GR. I don't think I've ever seen them use GR, at any time of the year.

    Yes, I was referring to the reducing visibility and cloudbase.

    More lightning in Limerick southside without about 7 secs between it and thunder


  • Registered Users Posts: 3,116 ✭✭✭dashoonage


    Yup two more rattles just outside limerick.

    The dog growled...then decided it was too much effort.
