The snow will be pushing up into the Alps from the south.
Hence why the southern Alps will potentially see a lot of snow (over a metre quite possible in the middle of next week). The south and west of the Alps look like being where the action is focussed.
The latest output looks cold for Scotland though not especially snowy.

Looking good, hopefully this snow will now stick around with much more to follow

It's at least positive on the cold front though with the likeliehood of some snow which is a definite improvement and at least Cairngorm can start using the new snow cannons they just took delivery of

18z another good run with snow arriving in the west late on 26 November into 27 November. The eastern Alps have to wait till a bit later, but a lot of snow to the southern and western end of the Alps by the middle of next week.

nozawaonsen, when you talk about western, southern and eastern parts of the Alps, how exactly do you define those areas in terms of coutnries and ski resorts? Thanks.

HISTALP has a useful map, but I tend to think of the Eastern Alps as roughly east of a line between Lake Constance (Bodensee) and Lake Como (so further west than it appears on the HISTALP map).

Ray Zorro, have a look at the HISTALP link above and keep in mind that "exact" isn't a word I'd apply to this. If you want to get a sense of the likely spread over the next week take a look at the map at the top of the previous page.

It's startling what a difference there can be in the weather and snow cover if you drive down into Italy through the Mont Blanc or Fréjus Tunnels. I guess the N/S divide will be very wiggly line depending on the local topography. For example, Courmayeur/Chamonix are very close in terms of miles (people ski it) but the difference between the weather they get is much greater than the difference between places much further apart in other directions. Last February I drove through Fréjus on one of the snowiest days of the last several years; there were literally a dozen snowploughs working to clear the enormous car park at Géant in Albertville, traffic on just one lane of the motorway in convoys behind ploughs. Out the other side was a different world; mostly bare rock and brown, dried up pastures. That big chunk of mountain dictates who gets what.
I imagine there can be similar big differences between, say, Innsbruck and the Dolomite resorts. The east/west dividing line is presumably a lot less stark, and more ill-defined (if a bit straighter).
The area where my apartment is tends to be described as the "préalpes" in French forecasts.

A few years ago I was driving back to Geneva on the old A41 (now the A410) and there is a little bit of a hill which goes up to about 800m (Col d'Evires). Driving up the hill it was raining, but the moment you crested the hill and started down the other side it was heavy snow with about 3 or 4 inches of slush on the road. Guess there was some localised effect.

I have held off, but it's time for my annual post!!
Does this mean snow for the lesser known Piemonte resorts?
Mondole and Limone Piemonte areas?
PLEASE!
We are going over for Christmas and it would be great to be skiing and not hiking!!
Thanks!!

Quite a foehn kicking up as the storm comes in next week.
http://www.meteocentrale.ch/en/weather/foehn-and-bise/foehn.html
Continuing tendency to slip it back in the models 27-29 now looking the main dates. But we are catching it faster than it is moving away.
And some chilly temperatures starting to crop up in the charts for the end of next week.

Hi Noz
Please can you explain the Foehn, is this a good or bad thing ? Cheers

rob@rar, you get those very localised effects, with quite small hills, on the A40 between Bourg en Bresse and Geneva too. The weather on either side of those long tunnels can be startlingly different. they have illuminated signs before you exit, giving warning of rain or snow, which are quite useful. I once drove out into very heavy snow - where there was just cold damp the other side. Persisted for some miles, but conditions weren't good and it was dark, so stopped off near Bourg en Bresse for the night.
It's exciting thinking now about driving in the snow.... won't be long. Getting the snow tyres on next week. Then a quick practice with the chains, and off to go.
harri20000, the foehn is generally a bad thing, also knows as the Snow Eater (or "the F-Word"). Someone with more technical knowledge will explain why.

a foehn is a wind caused by cold air on one side of a hill forcing the warm air over the mountain and down into the next valley, the warm air then starts eating up all the snow cover.
there quite common though and not totally destructive to the snow cover.
we had one in chamonix in the summer that actually reached around 130kmh an hour though....it bulldozed most of chamonix town centre and felled hundreds of tree's!!

one odd effect of a couple of days foehn is that where unpisted areas have been tracked, with ski tracks indented into the snow, they end up standing up above the surroundings, like railway lines - because they were more consolidated and therefore resistant to the wind, I suppose. same can happen with footprints, where people have walked. It looks very strange.

Thanks for the explanations folks, hopefully this will not happen once all this predicted snow has hit as will be a major let down if the snow all disappears as quick as it arrives !
Still I have 49 days till my trip so plenty of time for more snow to fall, if the snow gods would be so kind that is

harri20000,
As others have said a föhn (or foehn) wind can be a Very Bad Thing. If the effect is strong the snow doesn't even bother turning into liquid water - it sublimates straight into vapour. It's called a Chinook in North America where the record temperature rise is -48 to 9°C in 24 hours!
http://en.wikipedia.org/wiki/Foehn_wind
A close friend of mine is a glider pilot - and they love föhn winds because they are associated with Mountain Wave which can take them up to silly heights. They can also produce lovely lenticular clouds like this one over Mont Blanc -

Red Leon, 'So, that's told you, then! '
No, he's answering a different question. The words in parenthesis you have put in make it look like we answered the same question but we are both right. The SYSTEM is coming from the Northeast, which was the question asked, just look at any of the models. Wind and Precipitation rotate clockwise around low pressure areas within the cold airmass so the snowfall will come from different directions. The particular chart noza has put up shows the LP centred over Lake Geneva approx with a pronounced kink over NE Italy and Tirol, where the snow would fall on a southerly wind. The placement of the LP changes on every run, but it is likely to end up roughly there at roughly that time in 6 days. For example the latest run (today's 6Z) has the same kink but the LP centred over Marseille instead.
I'm not sure why noza thinks it's not particularly snowy for Scotland. Lowering FLs and a warm North Sea = this from MWIS: 'There is now significant evidence of early December being very cold: most mountain terrain becoming frozen and snowfall on at least northern and eastern mountains'. The is a reasonable chance of significant snowfall all over the UK in 1-2weeks (ie from next weekend) and it's as certain as it gets for the Cairngorms.
Love the photo above of Mont Blanc and the lenticularis cloud.

wigglies looking good for Val D'Isere/Tignes and hints of perhaps some more snow around the 1st-3rd and 7-9th Dec (but all too far away.....)

chamonix-meteo as ever have a very succinct view for next week:
EXTENDED OUTLOOK UNTIL THURSDAY NOVEMBER 29 2012
Tuesday : fœhn wind still blowing, with shower possibly running over from the south - uncertain. Wednesday : cold front crossing over with possibly heavy snowfall - uncertain. Thursday : cold and snowy - rain-snow limit dropping towards 700 m - very uncertain.

Well it would be nice to see the Foehn go first, and then the cold storm front to come in after, rather than the other way around. That low FL sounds good too.

Well for the Alps the weather, the snow, the wind and the jet stream are coming from the south for the middle of next week.
This means the southern Alps will benefit more from the snowfall than the northern Alps.
What I said for Scotland was "the latest output looks cold for Scotland though not especially snowy." It still looks cold for next week and there will be snow, but it does not look like large amounts compared to what you might expect on the Scottish mountains at this time of year.
