Snow and Ice Warning : Saturday(PM)/Sunday 9th/10th December - SEE MOD NOTE POST #1

MOD NOTE

This is a busy thread and as a result the Mod Team will be taking a zero Tolerance approach to trolling and flaming

Don’t say you weren’t warned!!

And please don’t feed - report & let the Mod team deal with it

**It would be helpful to all that when posting weather reports that locations are added in the post ( this can be kept general if preferred) **

Thanks

As requested.

Sunday will be an event for many Northern and North Western areas. With regards to other areas it's a delicate situation.

To summarise:

Rain will move in from the southwest on Saturday night but will meet embedded very cold air over the country. It will turn to snow as it moves northeastward. It's a classic "battle ground" scenario between different air masses.

It will fall as snow initially over North Leinster (it will turn back to rain for a time). Over Ulster and most of Connaught it will fall as heavy snow throughout the event. Large accumulations in these parts. I would be of the opinion at least an orange warning is needed for these parts as of now - possibly red nearer the time.

Later on Sunday as the system begins to unwind and move away it returns to snow over Leinster and turns to snow in Munster with accumulations here. Not as significant but could still be disruptive.

As it clears it gets very cold and icy - another hazard in itself. Temperatures will plunge Sunday night well below freezing. Coldest night of the year so far.

This looks a severe event in the north and northwest including northern Connaught right now.

There is still the risk of significant snow further south as well. This is not 100% nailed in terms of where this will effect. Regardless many are going to see a significant snowfall.

I think it is safe to say this will be the most significant frontal snow event the country has seen in many years for the areas effected.

This is 48 hours out. There is no doubt it will be impactful.

Another risk is flooding, a lot of water associated with this.

I would advise people in the north and northwest - and Connaught - to keep up to date on forecasts and be prepared.

Hope Athlone gets a fair covering

George Sunsnow

The UK met office are changing their forecast frequently in this
The U.S met service live change snow forecasts DURING events

So no giving out about the Irish met service in one of the western worlds arguably hardest territories this far north to have a widespread snow event please

Anyone know what Kildare is expected to be like tomorrow thank you !

Speak Now

The only place is see consistently forecast to get a massive snow event is Wales. Some serious disruption for them.

How many times have met eireann changed their forecast today!!?? You would really think within 12-24 hours they could have nailed it down better. I mean changing forecast about 5 hours before the so called event is pretty bad. I know there are variables at play but they surely have access to a lot of weather models, you would expect a met service to be able to predict better within 24 hours. We will see what happens from here but it’s been like musical chairs today moving warning from one county to another. You would most certainly expect it 2 or more days out but not within 12-24 hours

Think of a game of roulette: one ball, a wheel with sharp edged slots that cause the ball to bounce in near random directions. Take a high speed, high resolution camera, super processing power, will you get the right answer while the ball is commencing it's journey?
Now, the weather is billions of times more complex than that (I'm guessing).

Let’s play a agame of letters on that one

Give me an L
Give me an O
Give me another L

They provide the information for the BBC forecasts
Note the BBC forecasters eg Schaffenacker are Met office or former met office staff
Their human input maps do not look anything like the above

Can you state your expertise in metrology that gives you such a standing that you can question experts?

I've very little knowledge, but I do know that Ireland has some of the most changeable weather in the world. Atmosphere is constantly moving, the Atlantic and the coastal mountains can mean last minute changes especially in volatile systems such as this.

Its also why its called a "forecast" not a "certainty"

It’s this type of response that annoys me. They are experts, they are paid to get things correct. By your reckoning no one can question them unless they themselves are meteorologists?

Where are the highest elevations within Dublin city and therefore the likeliest to have snow cover?

Is that the same one as yesterday that had large swathes of the midland well covered in Snow , the colouring seems a bit different but it was definitely an ECM chart ?

Up above Rathfarnham is often good for snow, its not stictly the city but not far away, Tickknock or the 3 Rock I think often catch a bit of snow at about 450 Meters.

In the county Kippure is the highest point at about 750 meters but it might be difficult to get up there.

I'm liking this GFS snow risk chart for 6pm tomorrow!

KingdomRushed

Now that the main rain-front is making contact with the southwest coast in last hour or so has anyone compared its timing/angle of approach to the various models? It would perhaps help ascertain which model is most likely to be closest to verifying

I like it as well! Met eireann have a different view unfortunately!

According to Mt's last update, anything below 150m ASL in Dublin won't see a whole lot bar rain.

Mate of mine is a mountain rescue, he says the amount of people heading up in snow ill equipped is insane, stay safe, and don't take risks.

Not aimed at you cameramonkey, just a general.

I don't know what's going to happen tomorrow but I thought I'd share my experience from Jan 1982 for the younger members.

It was Jan 1982 I was 15 yrs of age living in blessington due back in school after Christmas in city centre Dublin. My dad opened front door some evening early in January and showed me sheeting rain, no frost it was on my way to bed. Next morning my father called me and showede an imprint of the front door as the smile had drifted about 15ft in front of our house. We were off school for about a week I don't think we've lost out.
