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.

The photos are lovely,

Now where are the coldest parts of the country predicted to be? I can see traffic being a nightmare tomorrow morning especially in the midlands and west.

The roads in parts of Connacht and the Midlands will be treacherous in the morning. Its really neither safe nor appropriate that school children (and their parents/carers) who have to deal with treacherous conditions will still be expected to travel for school unless ME issues a Red warning, according to Dept of Education who say that schools will only be closed if such a warning is issued.

This reliance on the "Red Warning" system is not appropriate because they are issued on a county by county basis. Using counties as the basis for these warnings takes no account of the local nature of weather conditions- for example Clifden and Ballinasloe in Co Galway would both be operating under the same warning levels even though local conditions might be vastly different (as was the case today).

While I like the graduated warning system, there needs to be a better system whereby they can be applied on a more detailed level than county. With the detail of weather maps that have been demonstrated here today (temperature levels being presented geographically like isobars or contours) surely townlands could be used as they are already well mapped across the whole country. Then if we want to see how forecasts/ warnings will apply at a county or province level, it should easily be aggregated.

I think I was a bit too close to the sea to get much snow, just one inch. I'm just 3 miles south west of Athenry.
I got a good bit more in January 2015. But I took a trip to loughrea inland & the amount of snow increased dramatically to about 5 inches.
I thought the wind direction was north easterly so i don't know how the sea had such an affect.

Any traces of snow totally gone now in the suburbs of Waterford City. Cloud cover keeping the temp at 1.7c. Delighted to have got the snow we did but a bit disappointed it thawed so fast. At least my 5 years old twins had a chance to get out in it and have a laugh. Onwards and upwards for the rest of the Winter

-3.6 in Westport on my station. Lovely night out. It will be treacherous in the morning. Both secondary schools closed. Reasonable decision.

Its not reliant on a red warning system. The schools board of management will make the decision tomorrow which is exactly the way it should work in a situation like this where local conditions vary wildly. Schools in all the areas with snows will make their own assessments the same as they have always done. The red warning blanket closures by the Dept of Education are usually during the time of the actual alert and are only a very recent phenomenan

For example In Kildare there hasn't been much snow however my school is up, then down a very very steep hill and as such if the temperatures for tonight come off we may not be able to get to the school safely. In such a situation the Principal calls it.

Camera phone snap from Cruagh Wood earlier today, looking over Dublin. Really clear view of the Mournes in the distance.

I'm a bit surprised about predicted lows tonight. With quite a strong wind I would think a general 0 to -3 is about right.
I can't see any lower unless the gale calms down

It was great while it lasted. I was in Winterval today and up on the Waterford Eye at about three oclock and was amazed to see the snow coverage across the roofs, fields and especially over towards the old Ardree across the bridge, even though it had all melted in the City.. bring on the next rollercoaster ..

Used to do that as a kid so I can't condemn it.
Many a morning the milkman or postman nearly came a cropper.

I cannot believe people on the M7 and M8 are tailgating in these conditions!

Holy long distance Batman! Thats a fine shot. It's amazing how far south you can go and still see the Mournes when the visibility is good.

Some really cool snow pics posted here today.
It started off as light sleet here about 2.45 last night then turned to wet snow for a few hours that left a light covering on the grass and a layer of slush on the concrete and road. It all but thawed early this morning.

I take your points, and perhaps I wasn't clear enough in my main argument. The trust of my point was that

a) I like the coloured warning system in principle (very useful to provide guidance to us all in terms of when weather or other phenomena might impact daily activities.
b) Applying the warnings at a county level does not take local conditions into account. Therefore
c) A means of applying the warnings to townlands rather than counties needs to be considered.

I get the point that Principals/Boards of Management have decided previously whether local conditions force a school closure. Maybe I picked it up wrong, but an earlier news report was suggesting DoE had said that schools would remain open UNLESS a red warning was issued by M.E.

In any case, without using a warning system, when an individual school decides not to open, how are parents supposed to know in advance of sending their children out onto the roads? That's why we need a system that defines these arrangements more clearly. For example, if either the school or your home is defined as in a "Red Warning Area", then no school.. Otherwise, schools will open as planned. Clearly, DoE could issue an over- riding instruction at any time (even if warnings have not gone Red) if it considers the potential dangers to be high enough.

Regardless, I hope everyone remains safe in the morning.

I agree with you, thankfully some schools in West Mayo have decided to close, sun doesnt rise til 8.45 tomorrow, mobilising thousands of students in the dark on guaranteed icy country roads would result in some injury at least. Also the school environs, paths, driveways etc. would be very dangerous.
