Snow for some-Cold for all

kleefarr

Kilkenny City suburbs. (0900-1000)
We have had three snow showers, ranging from light to medium. Each only lasted at most tens minutes.
Hope there's more coming, the kids were getting very excited.

If I was to pick a place from Late Tuesday onwards for a reasonable risk of seeing regular snow showers,I'd say Ulster/North Connaught and down the west coast as far as Kerry or West cork as the NW wind will favour showers coming in off the Atlantic.
Secondary risks would probably be North Leinster.

As the air flow slackens a bit later in the week,I'd include Eastern coasts or at any time an organised feature might develop and run NW to SE.

Lowest risk would be the South midlands and South East.

I'd imagine with minus dewpoints and low temps, that anywhere that see's a shower will see it as snow though inland and high ground is needed for guaranteed settling unless you see an organised band come down

Thats cold enough for snow with negative dewpoints but unless its heavy it will only settle on hills away from the north and windward areas.

Theres a chance the winds might go ENE on Wenesday/thursday depending on the orientation of the low in the North sea which would increase the risks of snow in Eastern areas.

06 GFS want to send a low into the south Irish sea which would have implications for the south East and East coast with more prolonged rain sleet and snow.
It might carry a mild sector and higher dewpoints with it, but certainly it might give a good dumping on hills and well inland should it go there.

And here we have a better low developing off the North coast and heading south east in -40 500mb air

That could produce a lot of snow

And finally heres the latest fax for anybody who isnt sure of the source of the air we're going to be getting on Tuesday

I dont want to downplay it, certainly MASSIVE disruption in the North and Northwest. However NOT EVERYWHERE IS GOING TO SEE SNOW. Anywhere north of a line from Louth to Cavan to Donegal it is a certainty will see some accumulations. Also down along the west. The further south you are the more marginal it gets. I would rate Dublin 50/50 for snowfall at the moment simply due to a slack airflow after Tuesday.

I've a chance of going to Letterkenny for Wednesday and Thursday night, my only probelm now is will I actually make it there and will I get stuck there Friday?

Great place to be this week. Still not sure about the end of the week.


Here is a nice chart:http://expert.weatheronline.co.uk/cgi-bin/geturl/daten/profi/en/2006/02/27/basis06/enen/rart_06022818_2706.gif?7f4515d5fed9313265964bbd3f491d59

even spain has had snow yet we still wait :S

darkman2

Snow possible in the Southwest (perhaps this will go further north). Have to watch this one on Wednesday: http://www.metoffice.com/weather/charts/FSXX00T_48.jpg?20060227073013

Villain

Is it not likely that will fall as sleet on lower ground and only as snow on higher ground?

darkman2

Snow at sea level on its northern flank. Here it is on GFS, too far south. Dont rule out this being slightly further north:)

And...

The above chart is for next sunday and FI but increasing tendency towards an East wind which would be dragging very cold air from a new cold pool the GFS want to create over southern Britain due to the snow cover they might have from thursdays system

darkman2

Thats not the same system Earthman. Thats a depression arriving later on. Unfortunatley thats progged to be too far south as well:rolleyes: Just seen your post now, looks interesting but as you say FI. The orientation and location of that low will certainly change.

oh I know it will
heres the associated GFS temps at 6am

I notice Darkman you've mellowed your expectations for snow in the last day or two.
Understandable given the output.
Maybe Met Eireann are right after all?

I still think they are being way too cautious not to at least say theres a risk that there could be disruption especially up north and they seem afraid of the snow word.
Thats possibly because they got such criticism on Joe Duffy regarding last novembers snow... and they are being conservative now
It would be a sad day though for forecasting if a forecaster muted what they really think might happen or what there might be a risk of happening just because of last november or December.
That was different and there certainly was a risk of extensive snowfall up north then.

Risk should be mentioned to cover bases.

darkman2

I think the west and north will get a pasting however the East and South as usual are sheltered from the flow. Just heard Met Eireann forcast for tomorrow with the East and South remaining dry. Did say as we suspect showers becoming more widespread in the Afternoon. 'Some over Ulster may fall as snow even to low levels'. I think we will get some showers here however I dont expect much if any accumulation because at this time of year we really need it to snow at night. Of course there is always the chance of more prolonged stuff in the South. Huge disruption in the North I think regardless of what met eireann say:rolleyes:

Excellant charts

Widespread heavy snow showers tomorrow with temperatures droppin!:D

Expecting accumalations towards nightfall..

The its a week of convectional snow showers and eventual disturbances
such as PL's etc.. Under such instability and low pressure things that cant
be predicted will form

Western and Northern areas are at certain risk of falls of snow in excess
of 6 inches over the next 3 days.. Northern Leinster and espcially the east
east coast are at risk of 3 inches to Wednesday night:)

Expect snow showers to band to longer spells of snow tomorrow so a
covering before dusk is more than likely:)

Gonzo

im not really expecting much if anything where I live except a dry, crisp, fairly sunny and frosty week.. usually northwesterly and northerly winds keep my area very dry and cold but sunny with broken cloud.. the showers always stay to the west, north, far northeast and sometimes north midlands. Unless some form of easterly occurs I dont think i'll see more than a few light flurries in the wind.

Supercell

Boards just went nuts there on me .

I reckon we may do better at this time of year on the east coast than maybe January in the same airflow as the power of the sun comparatively should aid convection overland and thus the showers should hopefully penetrate further inland and maybe even make it to the east coast.

I dont share your confidence WC. We are too sheltered in the East. We will be lucky to see a few flurries. Northern areas certainly baring the brunt:rolleyes:

I see MetCheck have issued a 'Severe Weather Warning' not long ago...



Red = high probability of ice/sleet/snow
Gold = Moderate risk

Still though, at least I'm out of the 'low risk' category

It's amazing how the weather manages to differentiate between the 6 counties and the rest of us. Mother nature must be a Unionist

widespread shower activity tomorrow so me prolonged..
Should start to ly towards evening... Expect a nice 1 inche
covering by Wednesday morning:D in most areas more in the north and west

I'm hope to be in Dongeal for Thursday, WC do you expect there to be much lying snow up there by then?

Yes upto 15/20cm on higer ground maybe more:)

Lots of ice too.. very dangerous driving conditons by then

This would be the same Donegal where blizzards were forecast last November. We are still waiting on the white stuff. Don't hold your breath.:(

lucernarian

You've made your call for tomorrow weathercheck, now it's certainly doomed:p

I am concerned though that the snow won't stick. There's enough precipitation for an inch of snow allright but that means little if it doesn't stick. Are my fears justified?

The met office radar has heavy showers already pummeling the north of Scotland.

Yes..

A constant hammering of prolonged and heavy snow showers for at
very least 48hrs...

I expect at least 10cm to have fallen by morning Wednesday to low-levels:)

The fact that the Meto havent realeased a warning for this region
just seems totally daft:mad:

There will definately be a covering of snow throughout the region:)

Gonzo

I see Metcheck have the city of London greyed out as no risk at all.

SpitfireIV

I seen that done a few times Gonzo, little tiny areas that have no color at all, I think its just a fault or something, be a bit weird to have one little area thats no risk at all

redman

Isn't this down to London being so warm that no snow gets in!!?:D

Villain

http://www.trafficscotland.org/viewsOrd.asp has a load of webcams, the one near Helmsdale is looking a lot whiter now

Gonzo

the belt of rain moving south has fragmented alot over northern ireland.

darkman2

Met Eireann just said snow showers becoming more widespread tomorrow night across the northern half of the country. Accumulations are likely they said:D (I take it that means Dublin is in with a shout) 12z UKMO -- Cold spell goes on and on and on .........

darkman2

Check out the NW GFS snow risk for tomorrow night. Happy days;) :http://n-w-cirrus.co.uk/gfsimages/gfs.20060227/12/36/uksnowrisk.png

I see , it must be nightime all day tomorrow then and theres going to be a volcanic eruption with the lava instantly freezing and causing the whole of the north to be on high ground...
" snow at night time on high ground only" or words to that effect yesterday on the farming forecast :rolleyes:

Why bother do a forecast for the week on a sunday when its going to be changed the next day.
A better forecast yesterday would have been to outline the risk of snow if they werent 100% sure ( though funny enough the Met office in Belfast and London were very sure yesterday )

I'm not bitter as I'm unlikely to see snow in a NW wind except for the odd flurry unless something big comes down.

lucernarian

Very interesting forecast by Ger Fleming there. Finally a proper forecast, and specific. The usual suspects in a northerly were mentioned, and the "very north of Leinster" might get its foot in the door:) Severe frost tomorrow night.

No forecast really beyond Tuesday night. They're keeping their cards close to their chests;).

LookingFor

The six one forecast said that "a few" showers may push into northern leinster tomorrow ("the very north of leinster", with a shower showing over Dub ). The charts for Wed & Thurs showed showers again over Dub. So..fingers crossed. I'm more worried now about the potential for sticking, particularly after the sun comes out. Although it looks like it will be very cold indeed, the temps in Dublin tomorrow looked like 3 degrees, -5 tomorrow night.

I notice Gerry Murphy's farming forecast from yesterday has now been put in the bin,like I said it should be in yesterdays thread.

Gerry Flemming has just been on with a much more realistic forecast.
3c max in Dublin tomorrow.

Snow on low ground and in the Daytime

Slippin Jimmy

What are the chances of Navan seeing a bit of snow tomorrow or over the week?

Pretty much everywhere will see snow this week.. whether you get
enought to have a decent covering or not is a much harder thing
to forecast. I would suggest that Navan will get a covering this week
at least:)

It should see snow showers.
Settling snow will depend on how many and how heavy.

It's a now cast situation really during the week
Subtle wind changes and clumps of showers with shallow polar lows could change things and snow distribution

lucernarian

Now we have to worry about whether the snow will stick or not as the precipitation for tomorrow alone will not be particularly intense. I'd say I have an okay chance at home but many will be left dissapointed.

I think that snow in Dublin is more likely to melt than stick but I hope for the sake of snow lovers in Dublin that even enough for someone to make a single snowball will stick.

I missed that, did he say snow in Dublin? Or was it a generic sweeping statement?

lucernarian

Metcheck.com have over 24 hours of light snow for Derry starting at 9 AM tomorrow:eek:

Shame there's no features showing up for Wednesday as there is a max of 2 Celcius forecast on metcheck. The lowest maximum I've seen for Louth and this would fall to around 1 Celcius where I live.

What kind of shops would have outdoor thermometers, something basic even?:p

Nah he had the symbol over Dublin,he didnt mention Dublin.
He also had the 3 over Dublin-you get the picture.

I'll sumaraise the week for ye.
Snow in Gozo's house,snow with Felix, probably a good dusting at least in both especially at Gonzo's.
Snow in Longfields and With WC.

A few flurries maybe with mothman and nothing down here.

But it will be cold throughout.

Subtle wind changes and shower clumps may vary this a bit.

Probably a few inches with To be _ confirmed up on the higher ground in Louth too.
As for Danno, he should also get a few inches before the week is out.

Oh and I almost forgot,Ashbourne should see at least an inch or two before the week is out also.

Villain

What about me in Maynooth till Wednesday and the Letterkenny for Thursday and Firday maybe?

lucernarian

Earthman has made a bad prediction there I think. Some snow in Gonzo's house?:D
