snow skiing alps winter 2011-2012
Summary

After some remarkable snowfalls over the Alps over the past month, it should be a quieter week weather wise, it should be mostly dry with plenty of sunshine. There will always be a NE/SW split, always colder in Austria ,and very cold to start, and always less cold the further SW you go, but bitterly cold overnight throughout. However with all sunshine it should be a great skiing week, however there may be an avalanche risk in some areas, so beware this.

More Details as ever on the Ski Club of GB website.

It should turn slightly milder as the week progresses but a large degree of uncertainty as to the medium term outlook.

Synoptic Patterns and Progression

As ever, my synoptic pattern is based on the GFS, this week there are some significant differences between this model and the others towards the end of the week. So there is greater uncertainty than normal for Friday etc.

Currently we see low heights over the Northern Hemisphere, right from North America as far East as Svalbard, Low Pressure over Eastern Europe, with High Pressure over Russia, with the Azores High (1028mb) and a separate High Pressure over the UK (1028mb).

The low pressure over Eastern Europe is feeding in cold or very cold air for all of Scandinavia and most of Eastern Europe as far west as the Alps (esp Austria). Milder over Western Europe but with winds from the continent, temps cool and settled over the UK.

Little change by Sunday and Monday, however the pattern over Europe has pushed a bit further east, still very cold over much of Eastern Europe, but milder SW winds starting to push east over Western Scandinavia. Remaining mild over most of Western Europe, cool and settled over the UK with surface winds from the continent.

By Tuesday, low pressure (with low heights) over much of the Northern Atlantic including Greenland and Svalbard. High Pressure now over most of Europe as the Azores High has merged with the High over the UK, This will start feeding in milder SW winds over the UK and Western Scandinavia. Remaining cold over much of Eastern Europe.

The Azores High pushes further NE by Wednesday and still feeding in mild SW winds over the UK and much of Western Europe. Still the Russian High keeping it very cold here, in between pressure around 1020mb, remaining cold over Eastern Europe, but slightly milder further west, now including the Alps. Upstream some cold air starting to be pushed down into the Mid Atlantic.

By Thursday, High Pressure again for the Southern Atlantic, it should turn a bit milder over Central Europe, as the previous mild air over Western Europe gets pushed a bit further east, but remaining cold over much of Eastern Europe. starting to turn cooler over the UK with a brief NW flow, and turning colder as well with low pressure bringing westerly winds over Scandinavia

By Friday, there should be High Pressure to the south of the UK. GFS gives a mild flat pattern with mild air, for NW Europe including the UK and Southern Scandinavia. Cool over much of Central Europe, remaining cold over NE Europe It should also stay mild over the UK for the weekend under this pattern.

ECM and most of the other models to an extent go for more of a NW flow, with a ridge over the Atlantic, up to Greenland, giving cool or cold winds over the UK, and turning it cold and unsettled over the UK for the weekend, however it should be a mild start for much of Europe on the Friday, but turning much colder over the weekend.

thanks Julian-tend to agree with your ideas-will enjoy the sun and snow conditions out to Wed perhaps Thur, who knows the way GFS and the other models are; best take it 2-3 days at a time, I'll just have to go in the bars/mountain inns a bit more if it turns 'orrible.
again tks for all the work you put into this area.

regards

John
Hope you have a great time John
