Worthy of a thread I think. Looks very wintry the next couple of days.

National Weather Warnings

STATUS YELLOW

Snow-ice Warning for Ireland
Scattered heavy thundery showers about Wednesday into Thursday. Rain will occasionally turn to sleet and possibly snow - accumulations of less than 3cm possible. Northwest areas will be most at risk. Slippery roads and paths too due to frost and ice, especially for sheltered spots.

Issued:Tuesday 12 December 2017 19:00
Valid:Wednesday 13 December 2017 11:00 to Thursday 14 December 2017 20:00

Looking like a very wintry day tomorrow with a bit of everything thrown at us. A post frontal unstable airmass pulling in the cold uppers again and what looks like a stream of various precipitation which would seem to have a better chance falling as snow showers on higher ground in the afternoon and possibly a fair chance of snow showers in the East towards late afternoon / early evening ?. Could be a lot of thundery hail showers too popping up anywhere, all in a fresh W'ly airflow giving a sharp windchill . Don't forget your hats and gloves.

A few models for comparison.

sdanseo · 12-12-2017 10:34pm

Huge comparison between the HIRLAM and most others regarding the amount of precip, be it snow or rain. Only the GFS broadly in line and it pushes it in a little later and further south.

Will be interesting to see what plays out.

We’ve gotten so used to it

Nationwide or for particular counties?

Mint Sauce · 12-12-2017 11:30pm

Don't know much about reading these charts, but that looks like alot of cold cold rain.

(indicative) GFS is lower res but it's same - long and heavy showers.

I'd be more hopeful in this situation for snow in Greater Dublin this time compared to the slider..

We have good land track which could make all the difference. It will be mixed precip but with some intensity we could see temporary covering and perhaps of a few cms. But it won't be around for long, but i do expect to see a few nice snow showers and would place the risk of temporary lying snow at around 50%

And if you're right it'll be at evening rush hour.

Meteorite58 · 13-12-2017 12:31am

Latest 18Z HIRLAM . Not much evidence of Temps dropping below 0C in any of the models.

Donegal Storm · 13-12-2017 12:46am

Meh, even in the unlikely event it does snow it'll just be a horrible slushy mess, I'd far prefer some nice thundery hail showers. Should be an interesting day out wesht in that respect

pad199207 · 13-12-2017 7:59am

Met Eireann going for falls of sleet and snow this evening

Gaoth Laidir · 13-12-2017 8:25am

Woopie, another northwesterly! I can't wait for the hail and sleet!

The most exciting part of these few days may be the lightning in some parts. I'm not too hopeful of snow at my level anyway (65 m), but hopefully I'm wrong. Eastern Ulster has the best (least bad) chance of snow to lowest levels, but further south and west I can't see it. On higher ground, certainly.

cherryghost · 13-12-2017 8:35am

Rain and windchill = Horrible morning

JCX BXC · 13-12-2017 9:24am

Knock airport has a chance of snow showers in its TAF from 2pm.

Larbre34 · 13-12-2017 9:36am

Strong ninja snow potential after dark this evening

Love the ninja snow.. but somehow I think this will just be rain again in Dublin

Akrasia · 13-12-2017 10:28am

Gusty northerly wind and a hail shower just started in Ennis

Temperature reading as 6c atm

pilly · 13-12-2017 10:29am

Freezing cold and lashing rain here on the Limerick/Tipperary/Cork border.

Kamili · 13-12-2017 10:43am

Just started lashing here South Dublin, about 6°

JCX BXC · 13-12-2017 11:29am

2c at Knock, and reported a shower of sleet at 9:30am.

Danno · 13-12-2017 11:51am

Showers driving through, blustery. Sleet at the end of the last shower. Temperatures didn't drop much below 5c all night and as a result all the snow has thawed.

Currently 5.3c/3.5dp.

pilly · 13-12-2017 12:23pm

By the looks of the lack of activity this won't turn out to be much. I'm just here hoping and praying for at least a ninja attack at about 4 so I'll get sent home early.

Temperature has dropped from 6 to 4 and wind is bitterly cold.

I'd be very very surprised if that happens!

DOCARCH · 13-12-2017 12:35pm

A mass of showers just off the NW coast now. https://en.sat24.com/en

pad199207 · 13-12-2017 12:38pm

Sleety hail shower in Naas

highdef · 13-12-2017 12:39pm

Big clump of wintry precipitation arriving into the west and north west now. A few sferics off shore of the Mayo coast.

You beat me to it, DOCARCH

ZX7R · 13-12-2017 12:39pm

Watching the BBC weather forecast there now and there chart was showing a lot of snow showers from about 3pm for the east of Ireland

q85dw7osi4lebg · 13-12-2017 12:40pm

Temps dropping, lots of precip around. This could very well turn into a semi eventful day.

AllForIt · 13-12-2017 12:58pm

Uggh horrible day in Castlebar, not raining at the moment but ground very wet from all the fully melted snow and a horrible bitter wind and very dull. Weather doesn't get more miserable than this.

Danno · 13-12-2017 1:04pm

First gale gust for December recorded: 42mph. Unusual for December to have to wait for so long!

Currently 4.6c/2.1dp.

Kermit.de.frog · 13-12-2017 1:26pm

Euro4 6pm

Sleet and snow showers progged overnight and widespread.

km79 · 13-12-2017 1:28pm

Bitter cold

AirBiscuit · 13-12-2017 1:41pm

Rain shower that just passed Mulranny had a few flakes of snow that quickly melted when they hit the window.

yorlum11 · 13-12-2017 1:56pm

Intense shower of sleet between Westport and Castlebar now. Trying to snow. Temp dropped to 2 degrees in it. Might be an interesting evening ahead.

AirBiscuit · 13-12-2017 2:07pm

Sleet again, much heavier this time

Pete2k · 13-12-2017 2:12pm

Earlier hail showers have now turned to proper snow. Ground too wet to stick tho. West roscommon.
Edit: it's starting to stick to the grass. Ground must still be pretty cold as we still have lying snow in sheltered spots from Saturday night

ltdslipdiff · 13-12-2017 2:17pm

Waterford city bright and sunny - may head to Tramore for Ice-cream !

tom1ie · 13-12-2017 2:20pm

Saggart village on the Kildare/Dublin border, sun is out, feels fresh compared to earlier on which was bitterly cold. Calm before the storm?

konman · 13-12-2017 2:21pm

Snowing in ballindine co. mayo, not lodging yet.

JanuarySnowstor · 13-12-2017 2:21pm

Well the main trough is just hitting the west coast now....The proper cold is behind this so turning much colder as this passes through. Also convection looks very strong so quite likely that this will aid showers to turn wintry.

It's a 24 hour event at most but a potent one that should at least deliver some snowfall...
Lying snow possibly just for very high ground

I'm only at 75m asl and sticking pretty good ere now

AirBiscuit · 13-12-2017 2:31pm

Went to full snow, definitely wasn't expecting that this far west.
