    Could you produce a sounding for my location again please. (Just not on the immediate coast)

    Try 55.05N and -6.92W

    Closest I can get, 130 m amsl.

    Even though it looks to be small amounts - there's been 10 page threads running here for far less!

    Me too

    Thank you. Is there anywhere nearby that is sea level when the front arrives?

    You don’t want a polar low. It just warms the air and produces a lot of wind.

    Maybe not if you are near the coast, but over the years we've done well from Polar Lows. Although we tended to get proper Northerlies back then with a feed straight from the arctic.

    we've waited all winter for some decent upper cold to come in, well it's coming on Friday with -11c uppers over Dublin according to the GFS...... but it's looking dry for that particular timeframe in the east. Friday morning is actually looking interesting for falling snow at least, I'm surprised by the relative lack of talk about it here, there's some snow showers along the north and west coasts with a band of more organised snow sliding down the east coast.

    the ECM unfortunately disagrees with the GFS in terms of precipitation, the showers in the north and west are more like wintry showers rather than snow and the band of snow along the east stays offshore. the AROME doesn't quite run out far enough for the north/west but it shows the band of snow grazing the east coast so better than the ECM. the ARPEGE keeps the north and west dry apart from the odd shower but it looks good for those in the east. the ICON just about keeps the Irish Sea snow offshore and looks dry for the north and west.

    that's insane and totally plausible in my opinion considering how low temperatures got so early on last night, and now some places have the advantage of a small snow cover if that hangs around.

    Temp In Dublin seems to have only reached a high of 1-2 degrees this afternoon, Baltic out there

    Will see how much wintry precipitation clips the E and mostly the SE tomorrow.

    Looks like an extremely cold night Friday into Saturday.

    Plenty of rain in the Northern half of the country especially the W and NW over the next few days.

    Breezier then of late, bit windy on the coasts.

    Mild air spreading in from the SW /W. NE remaining cold.

    More than likely will see a status yellow rainfall warning issued for Tuesday for Northwestern counties.

    The Met Office says hill snow in Northern Ireland tonight, but soundings not looking too productive.


  • Registered Users Posts: 23,299 ✭✭✭✭Kermit.de.frog


    This system will have to be watched for Tuesday/Wednesday. It's being shifted ever further south and has snow potential on the northern flank

    Some evolution to come here I suspect.


  • Registered Users Posts: 8,219 ✭✭✭Gaoth Laidir


    Nah, for me no. It's a sloppy returning airmass that we'll have at that stage. No direct cold source. Lower levels should be too modified to produce anything of note imo.


  • Moderators, Science, Health & Environment Moderators Posts: 11,738 Mod ✭✭✭✭Meteorite58


    ECM stalling and pivoting the front with following cold airmass on Weds on the latest run. UKMO has the front clearing to the S quicker. GFS does not develop the stalling front like the ECM and has it well cleared later Tues into early Weds which is the outlier here would reckon. UKMO showing very cold night Tues into Weds but this would be under clear skies for that to take place. Would have to lead with the ECM. Finely balanced atm, a few days out a long time yet to know with any certainty.

    A lot of precipitation to fall between Mon and Thurs AM

    Fair play Meteorite, at least you are in the right thread!
    There's a lot of talk about this in the plus 120hr thread for some reason;)

    The trend seems to be bringing this system further south as we get closer to the time, so if that keeps up it might only graze the Waterford and Wexford coasts

    Ah its because it always seems so far away :pac:, this one is creeping up and intriguing but will it look anything like being shown on the current ECM run which is by far the biggest producer of snow. What will be the position of the front, will it stall as currently shown ??


  • Registered Users Posts: 16,507 ✭✭✭✭nacho libre


    I have a feeling the GFS scenario will be the correct one.


  • Moderators, Science, Health & Environment Moderators Posts: 11,738 Mod ✭✭✭✭Meteorite58

    Well the ECM is looking a lot more like the GFS this morning nacho libre, GFS wasn't such an outlier after all it would seem. Big adjustment showing just a bit of wintry precipitation, less precipitation also although still quite wet over Mon and Tues and now clearing away quicker to the SE on Weds. Will see how it plays out.

    All Wednesday's snow has disappeared on the ECM 00Z. Basically no snow for anyone out to 10 day.

    The 12z ECM has shifted It back north again. With the South East most likely to see some snow, even if it looks transient on this run. Clearly a lot of uncertainty still. Worth keeping any eye over the next few runs at least.

    That would indicate high ground only, and I would agree.


  • Moderators, Science, Health & Environment Moderators Posts: 11,738 Mod ✭✭✭✭Meteorite58


    Yeah ECM now much slower to clear the SE than the other models, not huge cold following but pressure is low . Other models showing wintry mix now also. Looks like wet snow if it falls at this stage, mostly wet sleety mix would reckon but will see as we get closer what are the chances of some proper snow accumulations.

    Precipitation accumulations up again, warnings look likely.

    Rough idea of rainfall accumulations.

    Area of LP deepens over us and merges into other areas of LP and goes on to deepen down to about 958 hPa in the North Sea on Thurs and become very windy there for a time.

    GFS starting to make a little more of the prospects through Leinster and Munster for some snow late afternoon/evening Wednesday.

    Be an interesting one to watch.
