@stefoy4me, To be honest I will accept a long transfer, diversion to a different airport as long as there is snow in resort for skiing.

My understanding is that a split sends very cold air south.

When that happened 2 years ago we had a long spell of cold and snowy weather in the UK.

Snow-forecast 12pm update brings more to 3v's than 6am. Was just over 30cm now showing over 50cm for fri-sat-sun. If it comes true and folks can get into the mountains and the resort isn't closed for avi reasons next week is looking pretty nice right now.

@Gaza, Netweather is showing that potentially for the first weekend of the new year.

Freezing end of the year in the Alps:
ZAMG, the Austrian Met Office (Bergfex gets the data from them) has been predicting a lot of snow in the medium term all over December, but it never arrived, so I would be cautious about those maps for Austria. yr.no and meteoexploration.com are much more conservative. This time I wish Zamg were right, we will see in a few days.

Shaping up excellently for Slovenia and South East Austria. Great news and just in time for my new years holiday!
Bring it on!

The Schilthorn Cableway in Mürren are using all available helicopters to collect snow and patch up currently closed slopes at lower levels to create a base before the storm comes -

I've not seen any evidence that ZAMG have been any more unreliable than any other forecasts? If you care to offer any I'd be interested.
As for this weekend's snowfall there is a wide range of options being produced, it seems unlikely all of them can be right (!). So I'd remain cautious on detail at this stage.
Re the impact of a disrupted polar vortex this would be likely to lead to the jet diving south allowing cold air to flow down into Europe, however that doesn't necessarily mean the whole of Europe would see cold and the UK could easily be left on the edge.

@nozawaonsen, re-read, examples given. And a few more in this same thread on previous days.
@red 27, that is at ~1500m, -25 is not unusual in Austria, even for some cities.
|
|
|
|
|
|
You know it makes sense.
|
@cota4000, examples of what? ZAMG being more out of line than one off GFS runs? Like I said show me the evidence.
Having lived in Austria for a number of years I can safely say -25C would very exceptional in any city in Austria.

Wow - that's a lot of work - why won't the new snow be any good? Especially on the track (second shot) - does it really matter what type the snow is for that?

@buchanan101, I'm no expert, but a heavy snowfall onto a non-existent base=high avalanche risk as there is no consolidated snow for the new layer to stick to. Normally in Autumn fluctuating temperatures cause a freeze-thaw situation over several weeks and reduces the ground temperature which stabilises the first heavy fall.
Experts please correct me if I am wrong.

Not sure I'd walk on it that quick. Rumour is there's a Porsche at the bottom.
Ever seen the ice jammer things (windsurfers on skates) from the top of the mountain?

I understand that part for slopes, but dumping stuff on a road/track thing seems unnecessary.

@Hells Bells, is the base nonexistent? Genuine question. Tignes has had 20 to 50 cm base over last several weeks (was more but clearly less deep now due to consolidation and freeze thawing)- is that enough for a heavy dump to bond to?

Simply put you get what is called a temperature gradient through the snowpack. Ground level is always zero and then the temp changes through the snowpack to the current air temp. If there is a thin base and very cold air this is bad for the snowpack which develops depth hoar (weak crystals which are sugarlike) With a thin base and cold air temp the temp gradient is very harsh, ideally you have slightly higher temps when snow first falls resulting in a lower temperature gradient. With really low temps due its better if you already have a well established base.
However this will only impact the off piste really. Pisted runs are stabilised by the piste bashing machines whose weight will effectively crush the weak layer in the base of the snowpack, or not allow if to form at all.
I suspect the Austrian are moving snow so that the all of the new snow will 'stick' so to speak and not got to waste. Cheaper to move it about than rely on running cannons later n the season. Take Avoriaz for example, half a meter of snow fell and 10 days later it was all gone. If there was already a base a lot more of that snow would have survived up to the season start. I guess the Austrians just want to ensure a very solid base in case the cold weather does not set in for any length of time.
Amazing news about the snow, so happy and hope it continues on its course!

Just out of interest, how does someone living in Austria for seveal years suggest that they are half German?!
Also agree that -25°C would be unusual in ANY Austrian city!

@peanuthead, on the lower slopes of some lower resorts it probably is non-existent. It appeared to be the case on those videos. Lots of people reporting green slopes all over the place.
I wouldn't call Tignes low altitude.

peanuthead. A heavy dump wont just slide off everywhere, it is all relative to slope aspect, angle and historical weather as well as how the new snow falls i.e. wind etc...The original base layer itself may be weak, we had rain high up not long ago which lubricates between the ground and snowpack making for very dangerous conditions. Also where the hardpack, freezethaw and winpacked snow is to be found the bond will likely be weaker between the two layers. Back in the day people would leave off piste to settle for a day or two before jumping around in the dangerous conditions. Now we are not so patient. But if you read the av bulletins and just use your head its not an issue.
Best bet in any resort is simply to ask the pisteurs who will have been up there blasting it or should at least have some advice on the snowpack.

Thanks@R555MAC, though would I be right in thinking best thing that can happen right now is big dump. Once that consolidates it will bridge weaknesses in base. The bigger the dump the better. Is that correct?

GFS 12z op has first snow arriving in Switzerland and Austria tomorrow lunctime (Thursday) and strengthening on Boxing Day (Friday)
Second heavier band reaches French and Swiss Alps on Saturday morning, spreading across to Austria and Italy by lunchtime and in play through Sunday. Light snow lingers in Austria on Monday. Looks like it moves through slightly faster on this run, but that's likely to shift back and forth. Still looks cold as we head to the end of the month. Austria looks like it may pick up some more light snow on Tuesday night/Wednesday morning.

I am liking Cham Met's update for Saturday 27th...
"SKY CONDITION : mostly cloudy to overcast. Period of sunshine close to 0%.
PRECIPITATION : probably continuous ‑ at times and locally heavy in the morning ‑ rain‑snow limit towards 900 m in the morning ‑ dropping towards 500 m in the evening ‑ expected snowfall towards 1500 m : 30‑40 cm.
WIND - aloft : W ‑>NW strong ‑ at times moderate to strong.
TEMPERATURE : dropping lows."
Wind could be lived without but a little snow will be most welcome for next week's onslaught.

Overcast and leaking from the heavens here in Sport Amadé. Just driven from Wagrain to Schladming via Altenmarkt and Radstadt and light precipitation is falling from the skies - sometimes sleet, sometimes graupel (small balls of snow or ice). I think this is the first of the fronts that were predicted to pass swiftly over us. More to follow in sequence over the next few days, but so far no warnings here of a "snowmaggeden-type" event, so it should not cause any travel chaos at this end.
