Yeah some feckin rollercoaster, nearly finished all my January wine stash and its only the 1st!

Be interesting to see the weather after the news this evening, depending I suppose also on who is presenting.

were are you hearing this from far to cold for sleet id like to think

actually i meant to quote weathercheck who said "Looking at the next few days, there will be a weak band moving south tomorrow with some sleet and snow likely, then we have winds veering from North to East for 7 days or more"

also michael mcauliffe talking about band of rain/sleet/snow 2mor more focused on ulster/connaught

Does anyone see any snow for West Dublin this evening?

yea i think this should all be snow as temps are below 0c nearly everywhere and anything that falls will settle if it settles through the day it will through nighttime hopefully:D

Thanks SA for your, as ever, informative and well-put together posts. Is this a new feature that has appeared in the charts for tomorrow? ie have Met E taken this into account in their forecasts? Why are the conditions suddenly marginal for snow again- I thought we were well under the cold upper air by now?

No problem rc28, thanks also.

In essence, it has been showing up for some time, within the past 24-48 hours but it's still uncertain as to how potent it will be, or as to the amount of warm air in the mix.

I don't know what to make of the Met Eireann forecasts because the radio forecast certainly sounds a bit different to the online ones, with less of a mention of persistent snowfall tomorrow. I think it will be a case of watching the radar & seeing it's exact track..

Conditions are only a small bit more marginal because this feature will have a certain amount of warmer air associated with it, after developing over the North Sea, which is still relatively warm as of yet.

Also, the 6PM Radio forecast mentioned the threat of more sustained snowfall in Northern and Eastern areas from Tuesday onwards.

One dry night, good to freeze up the snowbase good and solid for the action later.
This could become epic

why the chance of sleet tomorrow? bit of warmer air in this polar low?

A trough requires energy generated from a temperature imbalance. There is always a warm sector, usually small, of varying mildness. It's normally a bit of rouge heat brought in off the Atlantic. However temperatures and sea temperatures are so cold at this stage that the "mild sector" is infact very cold aswell. Just not as cold. It could be just snow tomorrow - or there could be sleet, possibly rain temporarilly. The winds go Northeast and that is why the Leinster coast is at risk tomorrow night and some flurries on Sunday. With the ground temperatures so cold with all the ice and snow on them anything that falls is going to settle even hail or sleet - which if anthing is more treacherous then just snow.

hating weather at the moment cant take the bike out what a balls and after selling my car hopefully it will go away soon enough :(:(:(

LookingFor

Evelyn Cusack was just on the news...perhaps clarifying the slight change in forecast from 1pm. She said a (weak) band of sleet/snow would affect ulster, connaught and the northern half of leinster tomorrow.

So I guess that's where the more widespread forecast of snow for tomorrow comes from.

so we could have hail or rain even in ulster?

yep hopefully but i just recall some bad experiences with polar lows where we all expect snow and then temps go up 1 or 2 degrees.:o

yea that happens here all the time but this time i think we have a good chance as everything is frozen totally..... there now when i went out and looked at the snow i opened the window and icicles were hanging of it as well as this on the ledge it was so cold that you could see the individual flakes at a safe condition not even melted.. the flakes are so dry too when they fall out of the sky and touch the ground they actually brake up!

a perfect explanation!

Dr. Kenneth Noisewater

Evelyn Cusack seems to think the northern half of the country is set for a dusting of snow tomorrow evening, said it'll prob fizzle out a bit as it goes south but im hopeful

It isn't a Polar low, but one of those would be nice. :-)

Despite everything the last few weeks have taught me about the difficulties of seeing perfect conditions for snow on our luke warm rock, I can feel myself getting sucked in, yet again. Thanks Darkman

I should have bet money on Waterford being the only place NOT to get snow !!!! Its verging on ridiculous now !! :mad:

darkman2

NP - ECM at 192 is "interesting" and extremely cold for Ireland throughout with very very low temperatures and snow mostly in the East toward the end of next week as pressure rises. Still this would produce flurries and exceptionally low temperatures.

Quite extraordinary




Record low temperatures inland?
