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.

Some of the 00z guidance promises heavy snow for inland southeast, south and even southwest, low drops straight south once it reaches Clare coast ... Hirlam has it quite intense, Arpege not quite as good.

Rain will eventually change to snow in many places today, with possible exception of east coast.

Would have ruled out east coast 2 hours a go. Not so sure now. Temps and dps getting just a little nearer to more favorable zone in the last couple of hours. Interesting to see if that trend continiues.

Toddler woke up and yelled. Looked out the window. Not a flake. Kilcock. Back to sleep for this house

Flakes getting bigger here now - still doing a straight drop to the floor as opposed to floating on over in the ENE wind. 1.8c/0.8cDP.

Johnstown a full degree cooler.

Nasty night here with a biting E wind and moderate rain sweeping up the Irish sea. Dunno about temps, but I reckon I'm around the 3C mark. Starting to see a few larger sleety blobs in the rain now also. Very rare to see so much red over Ireland on the netweather radar

Hard to believe it could snow down here in north cork its close to 7 degrees where I am! When are the temperatures expected to drop so significantly?

Snow falling in Tallaght now- temperature there has dropped 1 degC in 30 minutes...+0.5/-0.4

Dublin Airport 2.2/1.4 at present on a road site there.

Around 1 p.m. to 5 p.m. would be your window of opportunity for snow, in north Cork, more like 3 p.m. to 7 p.m. in south Cork.

It may not amount to much but temperatures will take a sharp drop just before those time intervals.

Had to check just to see if we were still east northeast. We are...Surprising to see this given the strength of the breeze.

Light rain been reported at EIDW at an intensity of 2,8mm per hour- pretty sure that is moderate rain.

Yea impressive given the 10-15 knot easterly breeze.

Fell asleep on the couch around 3 and it was raining quite heavily.

Now it's chucking down handkerchiefs and sticking.

Temps went from 2 to -1 in that time.

1.9/1.1 now @ howth. Wind has pickef up notably in last half hour with me in north Dublin which makes the obs a little contradictory to say the least...

Super-Rush

I'm glad we got in a few extra provisions yesterday because we won't be moving for a day or two. Forecasts in here were bang on too.

Rock Lesnar

As expected its raining in my area of county meath

Danno

Proper snow falling now - moderate intensity. Not sticking yet as there is 10mm of rain to freeze out, so probably a half hour or so before that work is done. Hoping for an increase in precip rates to aid ground-covering. Radar looks decent. 1.0c/0.0cDP. Wind almost gone, just a slight ENE. South Laois.

DOCARCH

Very wet in Dublin 16 with icy/bloby rain....verging on sleet. 1.7c DP 0.8c.

Errill, Mountrath and Killeshin all reporting snow falling on LaoisWeather facebook page.

Heavy snow falling here in Laois and its sticking big time! Place is completely white already. If this keeps up then getting to work tomorrow might be tricky

SpitfireIV

Heavy snow falling in Carlow too now and sticking quite well considering the rain that fell!! :-)

What part of Laois?

KingdomRushed

Following a quick look out the window (Westmeath) a quick review of met.ie station data, and a review of local reports here it would appear that this event did not come close to delivering on its potential. Sadly what could have been epic snowfall has fallen as rain mostly, to this point anyway. Wrong side of marginal on the whole despite the few exceptions being reported.
