[b]Overview[/b]

There has a been a stunning week over the Alps, with heavy snowfall widely and over half a metre in places giving fantastic powder conditions. This week is a little bit more mixed in terms of temperatures and snowfall, but there does seem to be quite a lot of sunny weather on the cards to enjoy the fresh snowfall, with some very cold overnight temps.

[size=3][font=arial]As has been the case so often this winter, especially since the turn of the year, there seems to a battleground in the weather this week. [/font][/size]

[attachment=159869:9 Feb.JPG]

[size=3][font=arial]To set the scene, as seemingly usual there is low pressure over North America, the North Atlantic and a different area of low pressure covering much of Europe, feeding in cold NE winds over the Alps. The Azores High is ridging up from the South West over the UK, and there is also High Pressure over Scandinavia.

The battleground is to decide which weather pattern will win the Atlantic, or the cold weather to the North East. Over the weekend low pressure will push eastwards over the UK, this is set to slide to an extent under the High pressure to the east, with the potential for some snow over parts of the UK.

By Monday the low pressure is forecast to move away to the South East leaving the UK and a flow of Easterly winds, and depending on the weather model giving cool or cold upper air, but it does mean cold weather for the UK. Low Pressure also over much of Europe and the Alps, with decent snowfalls expected over parts of Italy.

[size=3][font=arial]By Tuesday we are back to a similar pattern to the start of the weekend, with Low pressure to the NW of the UK and to the South East, with High Pressure to the SW (Azores) and to the NE (Scandinavia)

Perhaps signs that the Atlantic may win out by the weekend, but no real sign of mild over the UK or over much of Europe, with 850HPa temps generally in the range 0c to -5c.
