Couldn't be more different (or better) that than the 18 and 00 runs. Thoughts?

micksup, wait for the ensembles and even if there's widespread support don't believe anything past T+180.
In fact the way it's been recently, take anything beyond T+96 as being pretty speculative at best.

Is it much different? Up until the 12th December (when agreement within the ensemble begins to peter out) it looks like 06Z forecast is similar to the previous couple of runs, perhaps with a little bit more precipitation in the forecast.

rob@rar, the operational was a big cold outlier in FI, I presume that's what micksup meant ?
Looking good for your weekend in Val d'Isere. (or will the lack of race reroute you to Les Arcs ?)

I tend not to look much beyond four or five days with the GFS ensembles - it just changes too much to have any value. Next few days looking promising though, especially at altitude and well timed for me I'm staying in Les Arcs, but will drive to Val d'Isere or Tignes for skiing. The cancelled race is a shame, but not a big deal - I'll just have to ski instead!

brian,
Thanks, Brian.
Although I look at the charts people post, I doubt I could make much sense of them even if I read all the available hints & tips on interpretation - so I leave the forecasting to others more able than myself.
I think it was the word 'operational' as noun and the word 'outlier' which confused me. I still have no idea what 'outlier' means - noun or adjective? Is it, perhaps 'a thing which lies outside of...' like 'outlying buildings'?
It's interesting to have such specialised knowledge available - even if some of it passes over my head.

red leon, there is a "sticky" thread at the top of the snow reports forum, where Brian and others tried to explain the basics to me last year, worth a read IMHO
Cheers,
Greg

kitenski, Red Leon, just beware that the images in that thread are references to wetterzentrale, which get updated regularly, and not a one-off snapshot. Hence the text doesn't tie up with the plots. But it should sort of make sense.

For those uncertain of the terminology FI = Fantasy Island
Having said that, I think it was a system similar to that which gave the cold weather last Christmas/New Year (-30ºC on the La Plagne glacier, for example).

pam w, not necessarily although it could be. However, some really cold air to the North meeting a moisture laden LP coming up off the med and there could be serious snow business.

In the slightly more realistic time frame - anyone noticed the pressure of the centre of the LP progged for Sun/Mon?

brian, moisture laden LP from the Med would be good news indeed, esp for Serre Che and LDA.

The latest run is showing a bit more confidence for moderate snow around Wednesday and then again on Friday. Temperature still fairly mild, so this may fall as rain at lower levels (below 1500m?), but higher altitudes should see a decent amount. My fingers are crossed for 60cm of fresh snow in Tignes by the weekend

926 or 925 has been hinted at. Of course, it could be 2hpa higher, and is unlikely to be 20hpa lower (nosebleeds all round).

This is from the Met Office web site:
"On 14/15 December 1986, the explosive deepening of a very active depression between Greenland and Iceland resulted in the central pressure falling below 920 millibars (mb). This is believed to be the lowest pressure recorded in the North Atlantic and, perhaps, the lowest in the world outside tropical storms and possibly the centres of violent tornadoes. The average atmospheric pressure is around 1013 mb, but the central pressure weather systems typically range from 950 to 1040 mb around the UK. "
What are the implications of pressures of this level in the Alps? Depends what's happening around, I suppose?

That pressure level will be somewhere up in the North Atlantic, but already it seems to have been downgraded. Whether it will have an affect on the Alps, I'm not sure. It may well help build the high pressure over central Europe which will make it more difficult to for the fronts (such as last night's) to move through - but I'd expect there to be plenty of precipitation with it in front of cold air, so if any one that can down there it'll bring snow. The models don't often get a great handle on these lows (the details specifically), so the situation will be a bit fluid at the moment. It'll have an effect on Scotland though. It'll pump some "warmer" (relatively speaking) air in Saturday, Sat night and then blast it with colder stuff once the centre moves off. I wouldn't go up there on Sunday, that's for sure - but Saturday could be quite good.
That 1986 storm got down to 911hpa, and I've read somewhere that there was one in 1996 that got close (don't remember it though).
