    Yep UKM cancels the low even though it develops reasonably at T36. Would appear game up for that

    Much better agreement from the gas eps of no storm

    Deirdre Lowe on the radio there said that on Thursday there is the risk of stormy weather, but there is a chance that this storm may miss us. So even the pros are having problems with this thing.

    Generally rain, sleet, graupel, thundery hail showers. Localised moderate snow showers on hills.

    B: Northern half of Ulster:

    Generally rain, sleet, graupel, thundery hail showers. Localised moderate snow showers on mountains.

    Good news for those who like snow as this scenario (low tracking further south) would bring widespread wintry showers on Thursday night into Friday morning.

    That is the exact same forecast except that the snow line is seemingly forecast higher in the very north....and there is only one Mountain, Errigal, in the entire target area. :D

    What about the Sperrins and Mournes? It also applies to Scotland too. Anyway, it's an aviation forecast, so not just for people on the ground!

    One mountain?
    Donegal has loads of mountains, the hills here have snow on them now.

    I might be mistaken but I understood that UKMO and Met Eireann share their aviation forecasts (and TAF's)? i.e. jointly do forecasts for NI

    Thought a TAF was 'per airport' or is that a NOTAM??

    Met Éireann's chart shows Ireland, UK and northern France. There are no international boundaries. It's the same with the UKMO's Aviation charts too.

    Here's the Icelandic Met's one, which is not copyrighted.

    The TAFs are done by the respective countries however, so the airports in the North are done by the UK.

    Yep, you're right Bob.What I mean is they share the information provided in the TAF's and they jointly provide the aviation forecasts (METARS?) for Northern Ireland airports like Aldergrove and City of Derry.

    Both are per airport, but a NOTAM can also be issued for a certain FIR ("airspace"). These are done by the respective countries, although a NOTAM may not be weather-related at all so it's the aviation authority that issues them. SIGMETS are done per country too.

    Wicklow gets by far the highest snowfall in Ireland..apart from Kerry the mountains are the highest in Ireland.However it is a much colder region than the south-west for obvious reasons. It is common to have metres of the stuff higher up in a cold winter like the last three.:D:D

    No, the UKMO do the TAFs for those. The METARs are just the weather reports.

    I think you'll find you are wrong.The sperrings or the donegal mountains get more snow than the wicklow mountains,certain mountains in donegal have been white for weeks.also the wicklow mountains gets a lot less precipitation than here and we are in a colder region.glad i could help

    You are deluding yourself...the 'hills of donegal' rather than mountains. Ring MET Eireann and they will put you straight. I was in Letterkenny last week and there was not a patch of snow in the 'hills' when I was there. The east is generally a colder region away from the milder Atlantic with more extremes when easterly or north-easterly winds arrive. Donegal or other ranges of elevation just do not get the same savage snowfall as the Wicklow uplands...youtube it and you will see for yourself. Th coldest temperatures are also in Wicklow, midlands and occasionally Cavan/Monaghan.
