National: Severe Cold/ Snow Discussion (Thanks to all!)

Bicycle

Just dropped from 8C to 7C here in Limerick City. But feels significantly colder.

We had a "spit" of hail/sleet for about 1 minute 10 minutes ago and thats about it.

Still quite breezy.

Oh yes, mainly grey clouds here with the occasional gap in the clouds.

Maybe the little sunlight we have at this time of day will dry the roads a little.

Sorry but there will be zero drying

12Z NAE precip accum for 48 hours

Compared to the 06Z run roughly looks like more snow for the north of the country and less for the south.

Of course that could flip again on the 18Z. Models are all over the place.

That's precipitation in mm.

Doesn't say if it's rain or snow. Big difference between the 2, no?

Roughly 1mm of rain = 1cm of snow.

Its interesting wherever the dumping happens. Actually I'd prefer if it happened away from me to be honest. I have animals to look after.

This is like watching a car crash, I cant look away.

That'll be because the sun is rapidly heading down to the horizon i.e. the sun is setting. I can see it out of my windows. Although I do see more cloud following on the sat pic link posted earlier

Looks to me the good stuff is still a few hours off yet.
Still, probably some heavy shows locally in the mean while.

I feel for ya and know where you are comming from.

I don't currently have livestock but my job takes me out in bad weather conditions so while I love the snow and bad weather I also curse it at the same time too.

Its a love hate relationship. Over all I love it far more than I hate it. Kinda like those chocolate covered crisps. Savoury but sweet. Odd eh?

M.T. Cranium

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:

K-9

Snowing here, East Donegal. Quite light yet but a covering on the roads though.

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