Cold Spell Discussion (Ireland): Cold/Frosty/Icy with Snow for some

maquiladora

Higher precip in the east and northwest on the 12Z NAE. Looks like another adjustment west.

Conrach

Snow information UK have just tweeted that they expected the UKMO to upgrade to a red warning for NI for tomorrow.

Yep some high precip amounts, Wicklow mtn could get buried.

But still have to see the other data before we see where the crucial -5c line is and more importantly dewpoints.

The orientation of the low is not clear from the accum precip charts.

gbee, rain in measured in mm not cm :P

Just an observation on the fronts, after the present, due to pass over us on Sunday onwards.

The present front is here in Cork now where it is raining. Its quite mild out. In fact according to the 6z GFS the uppers at noon when the front landed were around +3. On Sunday, the present guidance is that the front landing will have -4 to -6 uppers accompanying it. That's a ca. 9 degree difference in accompanying uppers. It will also then run into the easterly -6s coming from the UK. You'd have to give that a helluva chance of falling as snow everywhere......

NAE could show disruptive for some areas.

Obviously usual coastal Dublin the last to see it etc..

Rain has arrived in Waterford too ...

6am. Almost identical to the last run so far.

12z NAE for tomorrow morning

Graupel

That pink is creeping closer to the south east on every run, I've an early start tomorrow so hopefully get a chance to catch it before it turns back to rain.

Tom Cruises Left Nut

The pink has made a definite shift west at midday

maquiladora

Yes, shifted a little further west and a little further south.

Uppers slightly colder in those areas.

Tom Cruises Left Nut

Also DPs and Uppers better

Saganist

Judging by 12Zh NAE, would I be right in saying that most of Dublin / Meath / Most of Leinster will get a good douse of the sneachta by Midday tomorrow ?

I noticed that too .. I know nothing about it but is it likely it could keep creeping closer??

maquiladora

Rain turning to snow over a wider area on the 12Z NAE.

Tom Cruises Left Nut

At 15:00 the snow is still a tad further south than on the last run

Probably not as far as Waterford, But East/North/Northeast Wexford may see something in the early hours.

-10 uppers reaching the northeast Ulster coast at 33 hours.

-8 reaching the Donegal.

A definite upgrade Maq

We deserve it at this stage !

Wicklow Mts have higher snowfall accumulation on the NAE than anywhere in the UK at 33 hours.

The GFS a world apart compared to the NAE. NAE has -6 uppers on the East Coast, GFS -2 uppers...I expect a major upgrade on the 12z GFS...we'll find out at 15:35 or so...

NAE is higher resolution than the GFS though. Global models can miss small scale differences like that.

Why does that not surprise me, Wicklow mountains are just unreal for snow. Might go up there and take some photos at the weekend if it's even accessible!!! They are like the scottish highlands when it comes to snow. Ski resort potential :-)))

It looks like rain all the way for most of us here in Munster. Enjoy the snow everywhere else.

ninebeanrows

NAE very good, for marginal areas of east Dublin/Meath/Louth still need a further shift south of the Low Feature to secure settling snow!

maquiladora

At 42 hours. You can see the small area of darker purple in Wicklow (40cm), higher than the area in south Wales which is under a UK Met Office red warning. That should tell you what conditions would be like there if this model was right.
