Snow and Ice Warning : Thursday/Friday 7th/8th December

Gonzo

BBC's forecast today is also very similar to Met Eireann's. displaying a repeat of the cold spell we had last week, just that it might be a slight bit of a colder one.

These threads are great craic you get the knowledgeable posters stating what they THINK and only that

Then you get the people reading as far as SNOW and not the rest and getting out the snow boots

Then you get the posters coming in saying everyone is WRONG and nothing will happen will just be cold

all great craic always worth a visit to the weather forum

Forecast on rte just now generally in line with this thread I would have thought. Certainly a reasonable chance of snow still, Connaught / Ulster / West Munster best positioned.

This pretty much, will require some luck for anything of note on lower ground in the east between now and Saturday. Other areas will see some decent falls I think. The question is whether or not mesoscale features pop up to deliver to other areas.

Seems to be a well organised trough crossing down over country on Thursday nightI

Think my kids were 3 the last time there was enough snow to build a snowman properly in Sligo town.

I wait with baited breath to see if this weeks wintry showers will result in a hailman a sleetman or a snowman......or indeed a rainman.

GFS Control run sends a slider south of Ireland towards Sunday/Monday bringing streamers to the East Coast! :eek:

Yeah pub run is on steroids

Friday morning rush hour could be fun in the north, north west and east -

Here's the possible slider/Irish Sea streamer scenario from the control run later on -

Yeah the first outbreak in November was sourced from Scandinavia, we had snow from the north in Donegal around the 25th but it quickly changed to a NE'erly and stayed that way all week. The airmass in mid December was sourced from a northerly though, once the airmass was in place we had easterly winds but they were very light and more a case of an already cold airmass passing over deep snowfields

Yes. You only have to re-read M.T Craniums post from that time to see the airmass that gave us snow on the 16th was northerly based out of the Canadian Arctic before it changed to a north easterly, which left us with a week of very cold and dry weather to enjoy the snow.
Normally with our wintry air masses the cold is diluted by the Atlantic influence over a day or two, that airmass on the 16th was exceptionally cold, and because it was so unstable, played in our favour also, which is why i had more snow than you:P.

Regarding the latest GFS, this model tends to exaggerate cold and storms, it's also not as accurate as other models in terms of verification, so i won't be taking its latest run too seriously.

What usually happens on the day is a blend between the more sober ECM and the ukmo. With that in mind i expect a two day toppler then back to milder weather for a few days. The northern arm of a split jet just seems too strong to allow proper blocking to occur.

A good 30cm in 24 hours :cool:




Snow potential aside though it should still be an interesting few days in the coming week, some nice kinks in the isobars as the front passes through on Wednesday so could be a squall line and a few sparks, plenty of wind and squally/maybe thundery showers as well.

Thundery hail squalls are one thing I've really missed since moving from Donegal, December 2011 is the last really active month I can recall

This event being a particular favourite

God Id love to see some snow. Was just a wee school boy last time I got to see any

Was the thundersnow of Nov/Dec 2010 something common enough with heavy snowfalls here? It was the first time I remember that happening, and it was glorious (because I hadn't seen either snow or a decent thunderstorm in quite a long time!)

I just googled what a toppler is. I don’t know how much more of this build up/close call/snowticipation followed by deep, deep disnowppointment I can take. I’m a wreck and it’s not even proper winter yet. 2010 has wrecked me. I live every winter now like this. On the edge of my nerves!! It’s a tough life living in hope with not even a flurry to tide you over or keep you going. I live in Donegal ffs. But I must live in the worst part. The no go snow area. Sigh .. Thursday. I’ll wait to see what happens on Thursday and then I vow never to get sucked in by the hype and hysteria ever again and just live my life.

Haha I was like that for 2 or 3 years after 2010..can only take so many years though. Really killed my interest in weather !

No. It is not that common here. It was courtesy of a very cold airmass aloft travelling over and interacting with much warmer moist air below- the sea.
Falling snow dampens the sound of thunder but lightning appears brighter than normal because it reflects off the falling snowflakes. It was a sight to behold for sure.

Another way in which 2010 will be hard to beat for a long time to come then!

High chance Thursday to Saturday

This mornings GFS has a deeper low and passing near and a higher pressure high in Greenland. Interesting times ahead.

EDIT: Looks like the cold weather wants to hang around a bit longer!

I wouldn’t say anything based on the morning gfs
Best are the overnight runs
The answer is unknown tbh
