Severe Frost countrywide + Occasional Snow Showers in the East from Thursday 9th Feb

About 2 bits of snizzle just fell, let's go crazy, I'm calling in sick

Large blobs of moderate/possibly heavy snow moving into eastern England now. In addition, a developing snow shower is heading for the Belfast area. Hopefully the Irish Sea will spring to life soon. Air pressure where the moderate/heavy snow is developing in eastern England is almost identical to many eastern areas of Ireland. Temperatures are also very similar however Ireland has much more favourable DPs.

IOM = Isle of Man. The shadow is the break in precipitation heading north west you can see on the chart, the blue areas have an Isle of Man sized hole between them.

Thanks. I knew the isle of man bit but didn't understand the shadow bit! Are you saying the precipitation falls on the IOM as it passed over it?

Never say never but none of MTC's forecast, MET E's forecast, the GFS precipitation charts (which frequently show rain as snow) or the Euro 04 model would give you much hope of snow this morning.

The one shining light remains the Hirlam model. It uses "hatching" on Meteociel (where I get it from) though and I always find the "hatching" a lot less accurate than the use of different colours (eg. pink) to connote snow.

Anyway the big interest seems to be a more organised blob of precipitation moving across the country tomorrow evening and overnight. Euro 04 has this as rain, Hirlam as snow. Hirlam also has snow showers today (in fact it has snow showers right now which is another reason to be sceptical...). See below.

Tomorrow night:-





Right now!:-



If I heard reports of widespread snow in the UK I'd start to get more hopeful for us but right now I'm not expecting anything for most if not all of us.

Google "lake effect snow". Basically the fact the cold air passes over the isle of man means it doesn't travel over enough water for showers to develop.

The Irish Sea produces lake effect snow (precipitation given it is not always snow) when the conditions are correct.
The IOM gets in the way as it interferes with the process. The IOM doesn't get the precipitation, it gets in the way of where lake effect snow is generated.

Any talk of snow is just wishful thinking.

Showers arriving into N Dublin look to have a bit more umph in them,

Not if one is on high ground in the areas that get showers.

Very true but the majority of people are talking about low level ie cities and towns

Doctor Shivering

There's going to be a fair bit of showers by tomorrow evening inland enough to get down to Kilkenny
For an alpine experience,Dubs should head up to the blue light or Johnny foxes or spend the night down in Roundwood or Glenmalure
I don't think there's enough follow on cold enough air to bring coastal snow but we'll see,the odds are against that but not ruled totally out

What we're getting really is a rogue break off of the continental cold pool
We're lucky to be getting that so soon as it normally takes 4 or 5 days for an easterly feed to bed in
That's not on the cards

Ref IOM shadow and lake effect snow.

Google "buffalo lake effect snow storm 2014" and have a look at videos, very recent good example. On a much bigger scale granted but you'll get the idea.

Just to address this,there could be some settling snow by Sunday morning in higher parts of south Dublin with a population of a 100 k plus down as far as populated Ballinteer,Broadford that type of area but maybe not to Dundrum or Goatstown
It's a nightmare to predict but not an issue because it won't be disruptive or anything for most even up there

I fear tomorrow will be too little too late, higher temps tomorrow means rain at lower levels. Today is going to be the coldest section of this spell and it will be mostly dry.

Looks like the layered cloud in the Irish sea will be breaking up soon, from Liverpool bay westwards past Anglesey. When this happens, convection is much more likely to kick off much as is the case over the north sea, fornenst eastern England.

There's a lap of the lower reservoir (10km) moonlight walk in aid of the Wicklow Hospice tomorrow evening in Roundwood, if anyone needs cover to get a partner up there!

Few intermittent flakes at Dublin airport. This AA 757 decided to de ice the wings before departure.

Associated mid level trough thats producing the showers on the east coast of the UK will make its way over us by midday tomorrow.

Current


Tomorrow



Best chance of showers will be just after this passes through. Should fall as snow away from the coast or above 200m.
