Around an inch in most places (dont want to jinx it by ramping
) but I agree more than that in spots, high ground for sure. 0 -

If the 18Z came off Carlow/Kilkenny would see snow.
Sorry, I meant except for areas well inland....oops

What happened to needing -5C or lower 850 temps for snow? They're not in place for tomorrow event. Also the dewpoints are looking very marginal for much of the east.
Am I missing something here
You need 850hPa temperatures at -0.1c or lower for snowfall. In Ireland we prefer lower because it cancels out the warming effect of the seas.
Our current airmass is so cold that it is 0c or lower the whole way up, way up above the clouds too. Anything that falls will be snow. The very costal margins might be wet snow because of the effect of sea-salt in the air.0 -
Absolutely bizarre conditions in south Meath. I have never never seen a frost like there was at 20:30 this evening. Everything crystal white. Even the road was white, with recessed tyre tracks in it. It appeared to a covering of ice crystals that seemed to be accumulating to a perceptable depth, like a covering of snow. Like moisture in the air is freezing into crystals on contact with surface. No clouds, no fog, clear sky, not a flake has fallen in a few days, but it looked as amazing as a covering of snow. Car was only parked 3 hours, and it too was frozen solid.
It wasn't so blo0dy amazing though trying to drive back up the N3 through the road works after the first few oncoming trucks had deposits clouds of muck on the windscreen :mad: No way of clearing it off when its that cold, could see feck all.
10 miles down the road towards Blanchardstown no sign of frost or ice
Surprised there seems to be no frost in north west Dublin, seemed like a fairly mild evening when I stopped to sort out the windscreen. Some frost on the southside though.
Guards seem to have run out of recovery vehicles. There was a rolled car abandoned in a lane of the N3 dual carraigeway just inbound of the M50 causing a traffic snarl up, usually the Guards recover them immediatley rather just leaving them there.0 -
Are you disagree'ing with the Great Eveylyn Cusack at 930 on RTE :pac:To_be_confirmed wrote: »There is utter wishful and nonsensical thinking going on in this thread.
Significant snow on Christmas? ONLY if you live on the Wicklow/Mourne mountains, and the high hills in Carlow/Kilkenny.
The synoptics seem good/likely for a hour's snow, maybe up to 3 hours at low areas in parts of Leinster. But where is this day's worth of snowfall coming from?!? There is no cold pool of air built up over this part of the world, just some cold surface air. Definitely will get in the way of the edge of the front and will make it snow but where are the numbers to support this??
My looking at GFS 18z tells me that there's not even going to be less than +2 Celcius dewpoints over any segment of the heavier rain forecast.
Her words were outbreaks of snow in the East followed by snow showers.
Those were her words not mine,now WC's
I'll believe it when I see it too but for a forecast like that you need back up from the mighty ECM ensembles and we don't have access to them.

Yep, i have the ssame thing, never seen any thing like it before.
Its just frost but everything is covered in white with tiny ice crystalls in the fog.0 -

Was sub-zero and frosty a little bit further east around Glasnevin with white footpaths at that time.0 -

Yes fantastic frost here this evening - there was no precipitation today so I don't know where all the fresh moisture came from for there to be so much ice all of a sudden.
I don't want people to be dissappointed tomorrow when/if it sleets rather than snows so it's best not to expect anything. The precip charts show this mainly as a sleet event but I don't know if they can be trusted.0 -

I was thinking the same thing myself. I can't see it happening but I'll be pleasantly surprised if it does!:)0 -

Whether it snows or not, I have at last seen something out this cold spell that I would class as remarkable 0
