Yeah a huge dumping for Scotland and the UK

Scotland is in the UK and the UK is quite big..places like Dorset, Devon hardly ever get snow..a bit like Cork..I lived in Dorset for a year and a half and it has extremely mild winters..akin to west Cork/South Kerry.

Light fall of hailstones now in east mayo

Great interview there M.T., given that this is a general chat I'll allow myself to congratulate you, surely your name is already known at ME offices, you're just getting more and more famous. Keep up the brilliant work!

Heavy snow here 5 miles south of Nenagh and it's sticking. Almost calm too after a strong breeze a few mins ago.

Lightened off for a while but large white flakes now falling straight down in dead calm conditions

I lived in Dublin for 5 years and it had extremely mild winters. Then winter 2009/10 came along. :pac:

Right now I'm just a bit concerned about the day after tomorrow.

Am I seeing convection over Dublin Bay ? ...

But they are not yet showing up on radar, "Streamers" from the NE winds maybe

premiercad

12Z GFS rolling and not bad at all still showing a PL skirting the south coast

It looks better for snow over a wide area tomorrow night / Saturday morning.

But that doesn't mean that is what will happened. The next run could show something worse again, or better....

What's the "rule of thumb"? Is it 1mm of precipitation = 3 mm of snow or am I just completely mixed up?

Common ratio is 10 to 1, so one 1mm ~= 1cm but this ratio can vary anywhere from 6 - 20

Large white snowflakes falling for about half an hour in East Clare.

Big change again on the GFS 12Z run its all over the place with that low, if it turned out correct there would be serious snow for the whole country fri night/sat morn

Woke me up they did.

Not really, was expecting the call ... hope you could make me out.

Seems that the cold air has rushed in so quickly that the sea effect is lagging behind, can't keep up so to speak, but convection takes place over land, this explains the earlier question about why snow showers mostly on land (so far).

From the radar and sat image, would expect the sea effect to catch up very soon and join the fray, but also, a frontal band has formed over Clare that could provide strong bursts of snow as it moves southeast this evening.

It's going to feel like -7 C outside in most of the country by 7-8 p.m. with the temperature continuing to drop steadily to about -2 C. Roads will almost certainly become icy and any slight snow cover will not help matters. I am expecting some very heavy bursts of snow with the sea-effect streamers arriving over Mayo and Donegal, extending further inland. Also, the five-day period looks full of potential and I've already seen the current 500-mb which shows the winds at 10,000 metres up coming straight from Greenland at 140 knots. A most unusual jet stream cutting right over the Greenland ice plateau.

Heading off to check the 12z GFS run now. :pac:

Really chucking it down here now (outside letterkenny) took some quick photos just as it started, hopefully in an hours time when i take more (light permitting) the ground will be white... actually looking out my window i cant see much grass already!!! It seems to be comming in short sharp bursts though of really heavy snow for 5 - 10 mins then 30 mins till the next shower!
