A new thread for a new day, it is going to be a very busy one i reckon, full of moaning, groaning, excitement and euphoria for some!

Enjoy the rollercoaster.

Precipitation likely to reach Dublin by around 7pm.

No big change on the 06Z for tonights snow. It'll be a nowcasting event anyway so at this stage models arent very useful.

You can see the edge of precipitation just coming into Scotland on the radar as it makes its way south : http://www.raintoday.co.uk/

according to the radio forecast this will be mainly a rain event with just some places on the back edge of the front seeing snow before it clears. apox on these mild sectors:mad:

is anyone even listening to me look at the rain today radar and you will see its all snow heading down from scotland and by the time it reaches here temps will hopeuflly have dropped....

nacho libre

am i right in thinking that it's most likely to stay as rain in the west, while further south and east there is more of a likelihood of the rain turning to snow before it clears?

ltdslipdiff

More bloody rain ! Head for the hills me thinks !!!

I thought the mild sector was looking to be quiet small on the charts last night?
Oh well, hopefully Met Eireann just being conservative not to get peoples hopes up.

sorry i didn't see your post. though given your location you are possibly more favoured to get snow. whereas down here that's not the case because it has gone the wrong side of marginal.

Looking at Rain to day, it looks like the big blob over Scotland is moving in a SE direction. And not due South.

I see that too, but that radar has been far from reliable to date... here's hoping I'm wrong though !

I see met eireann have changed their outlook for today , no word of accumlations of 6 cm anymore :rolleyes:
But in saying that just take a read of the outlook for the next week, it really is something else in the lead up to christmas

well it was evelyn who said it. she almost seemed downbeat giving the forecast. i hope you're right anyway.
i really couldn't take another letdown...

jambofc

after the first front moves threw with "rain/sleet/snow" and the real snow showers start does it not look like a northern event only with a line from say dundalk in the east to oranmore in the west????

the north looks like it's going to be plastered with the white stuff

Yeah it would be cruel if we went into a 5 or 6 day severe cold spell and the only weather front that is going to move over the country will bring frickin rain! :pac:

We should all take the old approach ,no tv ,no weather forecast ,not expecting anything , just open the door and buckets of snow

Looking good for christmas though

UK Outlook for Wednesday 23 Dec 2009 to Friday 1 Jan 2010:

It looks likely to be generally unsettled next week with a mixture of clear or brighter spells and showers or longer spells of rain, sleet or snow across most parts. Some heavier precipitation is likely but across southern areas the precipitation looks more likely to fall as rain or sleet. Cold, especially across northern areas with overnight frosts and icy surfaces in places. Windy at times too making it feel even colder. By next weekend it looks like the unsettled weather is set to continue but with the main sleet and snow risk continuing in the north. Temperatures may recover to near or above normal in parts of the south towards the end of the period but more wintry weather may continue in the north, although this aspect is uncertain.

yeah we have been waiting on this cold spell a week n a half now , keeps getting delayed!
Looked at the bbc map player yoke and it doesnt show much snow for ulster in the next few days.

And just to let you know that quite large differences in synoptics past 60hrs mean that 60hrs is FI at this point, shocking stuff.

The placement of those little lows change in macro ways from run to run.

New Met Eireann warning from now until...Christmas Eve?

From the satellite loop - http://sat24.com/Region.aspx?country=eu&sat=ir&type=loop , looks to me like the heavier stuff is clipping Scotland the the weaker stuff is going to reach Ireland later.
Unless that peps up i think its just going to be cloudy here with little if any precip in the east.

force eleven

Anyone thinking it is going to snow with this next belt of weather, may be disappointed, we have a brief milder pulse of air ahead of the front with the arctic air digging in behind. I'm more interested in it getting through and the rain out of the way, with the wintry stuff following behind.

Nice!
Just seen the bbc forecast on its website, it said there will be lots of snow showers in north ireland tomorrow.

I'd imagine you can include Limerick,Clare,Kerry and most of cork in that especially west cork.
The normal places that get atlantic showers really,the fact that they will be snow doesn't discriminate where an Artic sourced westerly sends them.

Latest weather warning seems to have it starting as rain/sleet then turning to hail/snow later. Yeah the north will do well from all those showers that'll be coming along behind the front.

nice to read but after todays downgrade i'm not getting carried away- at least until another hour when my annoyance at todays downgrade subsides:pac:

as usual scotland seems to be the place to be today if you are a snow lover. still i suppose half the fun is the rollercoaster of emotion involved in living in a country surrounded by warm water which can feck things over so easily.

The latest BBC news 24 forecast with their usually fairly accurate rainfall predictive sequence [to rob Eveyln's words] has most of the precip sliding east from the isle of man northwards...thereby bringing it into Northern England and out into the north sea.
They have a finger of it through Ireland going all the way south with back edge snow.

It's time to monitor dewpoints but I'd be surprised if it wasn't a short but fully snow event for the higher ground [including Annamoe] and well inland very adjacent to higher ground.
Sleet for the rest of us and maybe back edge snow but not much.

Then it's into the snow showers and the usual suspects are West Ulster but including all of ulster,heaviest in the west eg Donegal.
Connaught especially Mayo and sligo and then all down into west munster where the atlantic when it has been fed from the artic really can deliver potentially some monster showers.

I'd expect some showers to be strong enough to penetrate right into the midlands and East but if they give snow cover there,you can expect several inches at lower levels further west.

Something has fallen up here in the night, then frozen solid; bitterly cold.. Taking the dogs out to see the skies.. the mountains are lightly dusted with white.. Our Donegal postman was on time.. cats are in!!

Back later...

I think that front is weakening, and as someone already mentioned, the weaker portion is likely to come southwards over us, with the arctic plunge returning. Hopefully little or no rain, to keep the ground drier for possible snowfall accumalations later on

That northwesterly will blow those snow showers to all, but it will indeed be the usual northern and western spots most favoured by this time tomorrow.
