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.

MT Cranium may I ask about the Kildare forecast. Here in north Kildare and some of the models look like we may be missed entirely but you have 15-20cm? I’m on the hoping for snow bandwagon but just curious as to the discrepancy between posters saying we may miss out and yours. I’ve been around long enough to trust your forecasting and be jumping for joy at this particular one when I was on the downer section of the rollercoaster

I was thinking the same but wouldn't dare question him he's usually spot on. He is the only person anywhere predicting snow as far south as limerick and tipp

Lashing rain in Limerick city. Feels cold though, Shannon still reporting only around 4 degrees.

Starting to turn to snow now in Mayo going by netweather radar

GL's post in the technical thread is not pretty reading. One of the most knowledgeable posters you'll ever find on any weather forum - you don't want to hear him calling time on an event (in terms of widespread snow, not any snow at all).

For once, I hope he is absolutely clueless

Snow here now in knock -1 with a sharp east wind

Will snow settle easy on wet ground if cold enough?

Few small flakes here just now on the Meath Westmeath border.
Such a strange night so far though -2 and thick fog about 8pm then +2 at 11 and crystal clear, now at 12 it’s 1degree

Yes. We had two or three hours of rain before the snow on March 22nd (after a mild spell with ground temps much warmer to boot) and still recorded 8 inches.

More green (sleet), and some red now showing (snow), could be starting to swing more Easterly now (rather than North) so top edge might just clip Louth.

Incorrect - they emphasised from midnight onwards and from 3am onwards more widely. Already snow is falling along parts of the northern flank of the front in Mayo and Westmeath.

It does look to have stalled, or even gone back slightly at 00:15, probably rotating clockwise slightly as it meets the cooler Northern air. The green area is expanding slightly.

Where was Met E going with -6 tonight? Did anywhere even reach -2? I’m in Monaghan and heading back to Donegal and skies are clear and it’s about 0. No snow here and there will be none either.

Mr.Oxo do you know Met Eireann have predicted the transition from sleet to snow in the west midlands from 12 to 3am. It's happening on the latest radar. The east midlands 3am on. So they're to be investigated for what exactly?

The Shleet/Shnow trinunal!

Your username reminds me that i'd actually love an oul cup of oxo now:D

Very cold rain, fairly heavy, falling now. 5 miles North/slightly west of Tuam 60m ASL.
