After the Christmas break, this is the first forecast in 2013 and there will be a weekly forecast right through until April. Many times over recent years we have seen a very good start to the season, but things turning worse as we move into the new year. Will this happen this year. Very much an east west split this week, mild over western parts, but much colder for Eastern parts, with Austria seeing the best of the cold weather and the snow this week. Definitely a week to be on the slopes, and not worrying about long term conditions.

[b]Synoptic Charts [/b]



[font="Calibri","sans-serif"]The weather pattern starts with low Pressure over Greenland and the Western Atlantic, High Pressure ridging from Iberia through the UK to Western Scandinavia and much of Western mainland Europe, with a mild South Westerly flow here. Low Pressure over Eastern Europe with Northerly winds keeping it cold here. [/font]

[font="Calibri","sans-serif"]Little change over the weekend, but the pattern moving slightly further east, putting more of Europe into the mild air, with the cold in Eastern Europe pushing away further east. [/font]

[font="Calibri","sans-serif"]By Tuesday and Wednesday, the High Pressure covering most of mainland Europe, so the cold restricted to Far East and into Greece. Largely mild over the UK and the Alps during this time, however always colder to the East, with cold air fringing eastern parts of Austria and very cold for Bulgaria further East. [/font]

[font="Calibri","sans-serif"]Towards the end of the week a change in the pattern with Low Pressure over Scandinavia introducing a cold NE flow over Scandinavia and into the UK, and over Northern parts of mainland Europe Possibly turning very cold over NE mainland Europe, and generally turning cooler over the Alps and the UK[/font]

[b][font=Calibri","sans-serif]End of Week[/font][/b]

[font=Calibri","sans-serif]A change in weather pattern is currently forecast, so instead of high pressure with mild weather over much of the Alps. However Thursday looks colder, Friday colder still, with some snow pushing in from the North West down to resort levels. I will not go into that much detail at this stage, as it is a long way out.

Looking Very Cold Next Week over the Alps as colder air pushes in from the North, however this is a long way off.
