Wouldn't mind a bit of snow to postpone exams. They start on Thurs and I haven't started studying yet.:o:p:cool:

did you hear about all the Birds falling from sky in arkansas? also hundreds of thousands of dead fish washing up. Same In South AMerica apparently. All over the past few days. Looks like scenes from the Birds, the Hitchcock classic.
Saying maybe lighning or hail ..

00z GFS model is suggesting a small but still signifcant increase in the threat of snow for many northern parts of Ireland on Tuesday evening/night, the sort of change that would have snow on more higher-up spots (away from coasts) and not just the highest hills and mountains.

00z NAE seems to lessen the threat of snow slightly but that only has forecasts up to Tuesday midnight.

Either way, most low lying parts won't see any white stuff sticking on the ground but those who live higher up should take note.

A push of very mild air is quite likely around the 13th to 17th according to my research model, which has been doing fairly well on timing these sectors within a generally cold winter. The reason for it is connected with the strong retrograde activity across Greenland in December. As that builds further west and comes into phase with the Pacific ridge that was expected due to La Nina, there is a high probability of strong trough building in eastern North America, which in turn usually generates a more active jet stream and wave train from north of Bermuda towards Ireland. Although the background signals are cold, this episode is almost unavoidable but I also don't expect it to last much more than a week at most. It happens to coincide with a more northerly push of lunar tidal forces on the atmosphere, so that a stronger signal and then reversal could be expected than if this jet stream rise came with a southerly drag as we currently have in the background (these scales of interactions are rather subtle day to day).

The scenario with this mild spell looks conducive for a significant wind event to develop at some point, most likely in the period 16th to 19th at which time colder air should also be making a return. I am saying, then, look out for another kind of weather action altogether, strong westerly winds, something that has been just about absent from the scene since about mid-November.

This snow better not come back :mad: Sick of it at this stage..

Cleavage1970 · 03-01-2011 8:54am

i agree angel!! While its lovely to look at it's a total nightmare getting from a to b when it freezes and the roads turn to ice rinks!

Snow being reported in the South west of England on BBC radio.

very light snow starting in west limerick

ch750536 · 03-01-2011 11:28am

Snow lying on the floor here, grass & car covered, drive & roads clear. Snowing reasonably.

aurora 527 · 03-01-2011 11:29am

Am i right in thinking that this is only going to be a brief cold spell..:(

followed by wet and windy weather next week?

snaps · 03-01-2011 11:39am

The band pushing into Scotland and soon Ulster is very mild air. Temps in West Scotland risen from well to below 0 to nearly 10c, its 100% rain apart from the highlands.

Hard to say.
Models are very uncertain,changing things on every run.
Currently the flow is all from the north but to put it as simply as Dan Corbett did on the bbc yesterday,the artic door is only slightly ajar.So only a small amount of artic air is escaping at the moment.
It wouldn't take a whole lot of tweaking for the flood gates of artic air to open but thats not modeled to happen at present.
It might and it might not.

At present we have decaying front trapped in some home grown cold [essentially modified polar maritime air that is over us but that has lost it's sea modification because theres no wind as pressure is high].
That home grown cold is enough to squeeze out some snizzle and very light snow from the decaying front.
Away from high ground that will hardly be noticed.

Going forward we see fronts moving down essentially governed by the milder Atlantic air which is prevailing in this north south flow at the moment.
When they pass,we have less of an atlantic influence but still a winning one it looks like in the sense that it will modify the polar air enough to make snow a marginal event.
Snow will probably happen but it will be more so enthusiasts snow rather than disruptive snow.
By that I mean,you'll get people posting here theres a blizzard in ballykillageery which will really be wet snow that sticks for a while but melts like mad , the minute the sun comes out.

There is a medium probability that the arctic gates will open fully and we'll get something more interesting.

Stay tuned.

can somebody explain the difference between wet and powder/dry snow:rolleyes:

Imagine it lands on the sleeve of your jacket. You'll be able to blow the powdery stuff away (a bit like polystyrene), whereas the wetter stuff won't move so easily.

EDIT: duuuhhh, you were looking for the difference in terms of its internal physical properties, weren't you?

:D

Probably the wet snowflake contains a higher percentage of liquid water and the dry one is practically all made up of ice?

cherryghost · 03-01-2011 1:05pm

06Z looking very positive for the week into the weekend. A very positive forecast with a few cm's of snow almost nationwide leading into the weekend

ellieh1 · 03-01-2011 1:56pm

Its snowing very lightly here in Limerick city at the moment!!:D

Someone would want to tell Met Eireann. They talk of snow turning to rain.

Today
Cold and mostly cloudy this afternoon with just a few bright or short sunny spells. Some light rain or sleet over parts of Munster, with a few snow flurries, but these should die out later. Some further rain or sleet will develop over north Ulster with some snow on hills there this evening. Top temperatures zero to plus 4 degrees.

Tonight

Cold overnight with frost under clear skies, with a sharp frost developing over Munster and south Leinster. Breezy and mostly cloudy over Ulster, Connacht and later north Leinster with some outbreaks of rain or sleet, heavy at times and with some snow on northern hills. Lowest temperatures between -3 and +2 degrees, coldest in more southern areas.

Tomorrow

Tomorrow, Tuesday will be cloudy and breezy with rain at times, some of it persistent and heavy, with a little sleet possible on high ground. But some dry spells too, best over south Munster and south Leinster. After a cold start, top temperatures in mid afternoon will range 3 to 8 degrees - best in the northwest and west. Winds fresh southwesterly.

Outlook

Cold for the rest of the week with temperatures below normal with frosts at night under clear skies and also some sleet or snow showers at times. Breezy Tuesday overnight with rain in many places, falling as sleet at times, mainly on high ground and with a risk of a little snow on northern hills. But some breaks in cloud cover too, with frost developing under clear skies, mainly in the south of the country. Lows -2 to +3 degrees. Wednesday will have some further showers or rain, with some sleet on hills, but some bright spells also. Wednesday night will cold and fairly clear with a widespread hard frost and some icy patches. Lows zero to -4 C. Cold and mainly dry on Thursday with moderate northerly breezes. It will be cold on Thursday night with a sharp to severe frost, but latest information suggests that a spell of windy weather, with rain and sleet will develop along the south coast around nightfall or so, and will spread slowly northwards overnight and on Friday falling as snow in many places, but turning back to rain from the south eventually. Weekend : Cold with some showers or rain at times, some of it wintry, mainly on high ground. Cold and frosty at night.

Weather Warning

Issued at 03 January 2011 - 13:22
Weather Warning
A band of rain or sleet will affect northern and northwestern parts of the country later this evening and overnight. It will fall as snow in places with between 2 and 5 cm of snow likely. This mainly on high ground, but some snow is possible at lower levels inland too.

cherryghost · 03-01-2011 2:29pm

The whole week is pretty much a toss up.

Tomorrow is looking slightly milder before temperatures dip for the week with snow showers speading southwards. Anything today or tonight will fall as light snow/sleet/rain.

The weekend is a mixed bag, there could be raining pushing up from the south or a renewed push from the north. It's a knife edge really, very hard to predict what will happen come Friday night. We could have more prolonged periods of snow that will continue into the weekend or we could have a thaw from some mild southerly push. Hopefully by Wednesday there will be clearer forecasts.

Let's stay positive for now

EDIT: I stand corrected. A slight upgrade for tonight. Tomorrow still looks like thaw city

El Horseboxo · 03-01-2011 2:44pm

There will be no more significant nationwide snowfalls this winter on lower levels. The odd heavy wet snow shower that might stick and feck off quite quickly. That's about it. Not negativity. Just reality.

Could you please elaborate? And what exactly is your scientific and meteorological reasoning behind this statement? I'd really love to here it...

Snowing very lightly here in East Clare

Reality or rubbish.
I'd say rubbish.

I don't mean you any disrespect because you could be right,just as much as you could be wrong.
But the science you are using is no science at all...to state something thats impossible to state for a few months as a fact.
Hence Rubbish.

The latest UKMO human forecaster forecast on news 24 has tonights rain widely turning to snow in inland East ulster but not on the coast of East Ulster.
They had rain everywhere else even rain for the wintry showers of this week.

Their graphic for the end of the week and mentioned briefly was a wall of white "at last" coming down from the north.
(Alex Deacon was the forecaster and he didn't say "at last"

but he did hint pointing at the graphic that the much colder air was going to break through by the weekend into northern scotland.)This was shown as all snow.
They didn't show the forecast chart for that so watch the faxes for features coming down from the north and the 510 dam line getting closer to the north of scotland by the looks of things.

Given that this new spell of cold weather we are entering into is more of a forecaster intuition forecast than a rely exclusively on the models one...then this forecast by Alex Deacon is the first real sign by them that something more interesting is on the way.

Very cold, Snow
