From a West Clare perspective, all I see is pure disappointment.

Next week still looking excellent
Yes it's marginal but heavy snow is surely a given for high ground

Sunday/monday is looking quite wintry now particularly across eastern and northern areas with a possibility of a dusting or possibly something slightly heavier is quite a few areas.



Bitterly cold on Sunday evening with a possibility of widespread snow across Leinster and Ulster. Blizzard conditions are possible on high ground locations such as the Wicklow mountains. Temperatures below freezing east of the Shannon.



Bitterly cold on Monday too with temperatures barely above freezing



Infact next week some eastern areas may struggle to get much above 2 or 3C at any point next week with temperatures below 0C for much of the time. The Western third of the country will be milder with temperatures closer to 6 or 7C for much of the week.

I think we will need more runs like this tomorrow to be more comfortable about Sunday and into Monday. Wouldn't take much of an adjustment to bring the milder air further east or even the colder conditions further west.

But as of now it looks like rain tomorrow night turning to sleet and possibly snow later in the night. This will clear by Sunday morning and then another band of rain moving in from the north-west on Sunday evening into Sunday night, this one could turn to snow quicker and stay mainly as snow across the east and Ulster. Sunday night could be fairly snowy and if tonights chart verifies many eastern areas could wake up to a small to moderate covering on Monday morning.

I'm not totally sold on this yet, tomorrows runs will be important.

Looks dryer after Monday but the cold pool seems to be intensifying across Leinster into the first week of January.

Certainly nice-looking charts down the midlands and east overnight Sunday/Monday, but the sounding shows just how a degree either way could tip the balance. Really relying on cooling Sunday evening before the system arrives.

Chart for midnight, with the Celbridge forecast sounding. Surface temp/dewpoint 0.5/0.0 °C, with a moist isothermal layer around 0 °C up to around 900 hPa.

this mornings run the snow for Leinster looks more marginal than it did last night, temperatures don't look as cold either, temperatures more like 0C or 1C tomorrow night instead of -2C (which was showing last night).

The snow depth chart for tommorrow also looks mostly clear of lying snow potential. Looks like we are more back to the wintry mix of mostly sleet and wet snow with lying snow more guaranteed for high ground.

That's the GFS you are quoting I take it Gonzo, on the other hand the ECM is cold enough for snow potential but the track has been shifting about the last few runs. Good chance of snowfall I reckon at this stage, how wet and long it lasts is another thing, does look like the Eastern half and more so Ulster, Leinster with the best chance of some lying snow.

latest gfs still on for some minor snow accumulations across the north-eastern half of Leinster. Parts of Northern Ireland and high ground locations such as the Wicklow mountains could get a fairly moderate covering if precipitation lasts for a few hours.



Could be quite alot of precipitation around between now and Monday morning, mostly rain in the west and south but more wintry in the north and east.



Once we get to Tuesday many places will see drier weather till the 3th or 4th of January.

In the above model it shows the snow for the Wicklow mountains, Blackstairs Mountains, the Slieve Blooms and the Castlecomer Plateau which are probably very realistic.

Weds looks interesting, models differ, most notably with track but worth keeping an eye on, some good cold 850 hPa temperatures available.

Watching that precip turn back to rain just as it hits Dublin stings. Hopefully more easterly days ahead for the capital before January's done.
