I really hope we get snow this christmas. So that all the flights will be cancelled, the sport called off, the footpaths and roads too treacherous to leave the house and life in general being made a living misery. Bring it on :rolleyes:

I thought it might have something to do with the shower as opposed to the cold front.

tntn - Make sure it's a warm one

Evaporative cooling maybe?
The melting snowflakes/evaporating water need energy to do so and take it from the surrounding air which in turn cools the air around it and allows snow to penetrate lower and lower into the atmosphere as it continues to cool the air around it.

Thanks Trogdor. After the shower passed it jumped straight back up to 5.7.

Another showers has just came in and it has dropped to 3.8C

Either that or the batters are going in the weather station:)

Hi Chicken Run. Do let us know if you get those snow headaches

WolfeIRE

I still cannot see much snowfall over the next 2-3 days, with the exception of high ground in Ulster and north Connacht. I maintain the best chance of low level snow will be next Tue/Wed in west Munster, Connacht and west Ulster.

Ultimately, we will remain stuck in this mild,cold,mild,cold setp in the run up to Christmas with the south and southeast fairing poorest regarding potential snowfall

Today Staying very windy and gusty this evening especially in the west and north, with further squally showers which will be heavy at times. Temperatures will start to drop and it will become cold.
Tonight

Winds will gradually moderate tonight and many places will become dry with clear periods. However showers will continue in western and northern parts and some will be wintry on higher ground in the northwest. Indeed some of the showers may penetrate further inland to parts of the midlands and north Leinster. Cold with lowest temperatures of 0 to 3 degrees with ground frost developing and the risk of some icy patches.

Tomorrow

It will be a cold, bright day tomorrow Friday with some sunny spells. Further showers will affect western parts of Connacht and Ulster, and some will be wintry in particular on higher ground. It will be breezy during the morning but winds will moderate in the afternoon, with highest temperatures of 4 to 7 degrees.

Everything has calmed down dramatically here in Donegal in the last half hour or so very little wind and no precipitation of any kind. I thought around now was predicted to be the worst period? Or has the front simply missed us?

it has gotten fairly gusty here again.

i wasn't holding out much hope for snow despite the promising forecasts earlier in the week, blustery westerly to north westerly winds are not conducive(?) to low level snow fall(bar ulster) from what i've seen over the years.

if the jet stream would do the decent thing and allow these system to plunge southwards, we might be in business with some of these cold snaps that follow the systems..

on a more positive note, i think one of these storms should deliver for much of the country before this period of active weather is over.

thetonynator

Kilkennyweather.com its reporting light snow, 4.2C. Surely a mistake! DP - 0.3

I think we will just about see the snowline to sea-level in any showers in the northern half of Ulster later tomorrow afternoon, with a mix further south. The snowline will rise fairly steeply to around 150 m through central Ireland, provided that any showers make it that far.

850 theta-w values of around 0-1 °C where sea level pressure is around 1000 hPa should make fairly certain that precipitation at sea level willl be predominantly snow. With pressure higher further south, the same value of theta-w will still mean that the snow line will rise, by about 200 m per 10 hPa rise.

850-1000 thickness at around 1290-1295 m is a little higher than the 1285 m max I would like, but evaporative cooling may just offset this enough.



The GFS lies in fairly close agreement, with the "Schneefallgrenze" (snow line) showing a similar pattern tomorrow afternoon.

I think Clare was about the only county that didn't get snow last year - was talking to someone who lives in Ennis yesterday and he was saying that they got no snow there last year.

Below was taken around Christmas Eve last year. Yes, Clare (and Waterford/South Tipp/Cork coastline) seem to be the only places that show green. Awful if you were a snowlover in those places :mad:

no chance of snow for most of us I'd say, that map of Europe showing snowlines looks depressingly bad just about everywhere throughout Europe, not just Ireland. There doesnt even seem to be much snow on the Alps or Eastern Europe which seems very odd. Snow looks confined to high ground even in scandinavia.

Slashermcguirk

That image of snow covered Ireland is great. Wicklow and Dublin really took a blast of snow! Hopefully everybody gets some this time around

Harps

Temperature has actually risen 2C here again, back up to 4.5C now, dew point was -0.9C now up to 1.5C. Not a hope of any snow here tonight by the looks of it

Back to mostly rain now after hail and graupel for the past 90 minutes

faktisperminute

had a heavy snow shower for 5 min .

That chart only shows the fresh snowfall for the previous 6 hours, not the total snow cover.

Tv3 about to show the snow from last year!

Harps

Finally something resembling snow here, small and very wet flakes which is pretty much what we've had all week already but a start I suppose. Dew point back below 0C and temperature on the way down again

arctictree

It's snowing here. +2.0c. Looks like a rogue shower from the radar. Also, I'm at 250M.

Could give some interest for our northern folk.
