    Just in relation to the cold front.

    GFS suggests potential accumulations of upto 10cm in parts by 9am.

    Leinster and the Midlands seem to be most at risk from this front.

    This seems totally at odds with what the latest Met Eirean warning is. They are saying 2-5cm in Ulster & Connacht with "much less" than that elsewhere?

    Weather Warning

    Issued at 04 January 2010 - 15:49
    Weather Warning

    Many parts of the country will have further falls of snow tonight and early on Tuesday. North and west Ulster, as well as north Connacht will have accumulations of 2 to 5 cm below 250m while other areas will have much less. However with frozen ground persisting generally, ice will remain a problem in most areas.
    A really typical warning.

    Mentioning the bankers like North Connacht etc etc.

    Even though this cold front moving south is more likely to bring snow to the midlands and leinster than those locations.

    As the cold front moves through snow showers will then become widespread and affect those areas and then transfer to the east through Tuesday.

    All this not including our potential Polar Low type feature.

    Temprature has just dropped again to below 0 again in West Dublin from a high of + 0.5. Still a whiteout here and not one footpath or side road gritted hence the thick ice and snow since New Year's eve. A joke. By the way lots of horse racing on. No snow in Cheltenham or Wolverhampton or the South Coast of England...make a fortune on betting in this arctic weather.;)

    Trust me my friend, ventilation is the answer as any older person who grew up in Ireland with only a turf fueled range and persistant damp and rain will tell you. The houses here need an exchange of air daily.:)

    BTW, any sign of snow yet in Galway???

    As my first words said, ventilation IS essential :)
    Heating is just as essential, that was the rest of my reply about :)
    But that only makes sense with proper insulation.

    No flakes here yet, I only expect some snow around 10ish... :(

    GFS is steadily backtracking with regard to the Easterly flow, almost there at T+102 and monumental changes compared with the last two runs.

    Meanwhile, GME/DWD is absolutely solid out to T+132 again today, with a very strong Easterly flow developing for the weekend::

    Didn't risk going to work this morning. Went down the path at the front of my house first thing this morning(in my wheelchair), and couldn't control it, so I didn't even bother getting into my car.

    Rang a taxi also, and it was involved in an accident on its way to pick me up!!!!


    Oh, and it's f***in' FREEZIN' here!!!!!!

    According to Ms Anne Doyle's forecast on the radio - obvioulsy updated by Met E - 'only north and north-western counties are likely to have snow accumultations'. :confused:

    The rest of that run seems at odds with the UKMO's last run that I saw though with that cheeky high pressure.
    Just goes to show that sub 24hrs is fi at the moment.
    It doesn't say a whole lot for technology and science.

    Was horrible this morning, its not slippy in Kildare but just outside the City Centre on my way to work it was pure ice on all the footpaths, lethal

    Cloudy here, but still not totally overcast :(
    It looks nicer to the North though! Maybe, just maybe...
    Frost was permanent the whole day where sun didn't reach. Maybe it's truly better *not* to expect anything at all :D it worked before....

    That's the big fuppin problem - the trough will be bringing a north westerly in front of it and lots of atlantic air.

    It's even falling as rain in Avimore in the heart of the Scotish highlands (at 0c).

    THe NAE 12Z has a potent little low pressure for just north of Ireland in the morning....I wonder is that my polar low??? :D The GFS doesn't pick it up.

    Also, as a guide for what's required for snow, the 850hPa wet bulb potential temperature is a good indicator (below). At sea level, the 0°C line means a 95% probability that precipitation will be snow.

    Unless the air modifies in some way (traveliing across Ireland), wind driection changes. Polar low would be good!

    Is that 0c, Air Temp or DP at sea level ?

    UKMO 12Z out to T+120, also holding firm on a renewed Easterly flow, which even develops at T+96:

    http://www.meteociel.fr/modeles/ukmo2.php?nh=&ech=120&carte=1021

    In addition, it is once again suggesting various occasions on which snowfall could be widespread, for example tomorrow morning in the East & Southeast:

    http://www.meteociel.fr/modeles/ukmo2.php?nh=&ech=18&carte=1594

    Later tomorrow night & into Wednesday, again the East and Southeast as well as parts of the Northwest:

    http://www.meteociel.fr/modeles/ukmo2.php?nh=&ech=18&carte=1594

    In addition, the latest UKMO NAE Model has snowfall into Eastern and Southeastern areas into Wednesday also.
