[size=3][font=arial][b]Summary[/b][/font][/size]

[size=3][font=arial]As we move into March things have warmed up somewhat, with spring snow conditions across the Alps, however good snow remains at altitude. Of course this mean that risk of avalanches remains. [/font][/size]

[size=3][font=arial][b]Synoptics [/b][/font][/size]
[size=3][font=arial]The weekend starts with High Pressure centred over Scandinavia and North East Europe. [/font][/size]
[size=3][font=arial]Winds are Northern Easterly over the weekend, and veers South Easterly for the start of next week, as the high pressure edges away to the North East for a time. This allows Low Pressure to edge in especially for Italy and at times other southern parts of the Alps so unsettled here for a time. [/font][/size]

[size=3][font=arial]Over the weekend and into next week, temperatures are around average for the time of year. [/font][/size]
[size=3][font=arial]Towards the weekend there is a level of uncertainty but the current trend is for high pressure to edge back in over Central Europe turning things more settled and colder in the east with a easterly feed. [/font][/size]

[size=3][font=arial][b]Precipitation [/b][/font][/size]
[size=3][font=arial]Saturday – A few showers are possible in the morning for SW Alps, perhaps becoming a bit more widespread and heavy into the afternoon, but always concentrated towards the South West. (French Alps, S Switzerland, NW Italy into SW Austria), Snow is likely above 1600m daytime, this dropping back to 1000m overnight.[/font][/size]
[size=3][font=arial][attachment=247015:Alps 13 Mar Precip + 24.png][/font][/size]

[font=arial][size=3]Sunday – The northern half of the laps should be dry throughout, however heavy precipitation is expected over Western Italy, is set to spread over the rest of Italy, and fringe Southern parts of Switzerland and Austria, giving moderate precipitation at times. [/size][/font]
[font=arial][size=3][attachment=247014:Alps 13 Mar Precip + 48.png][/size][/font]

[font=arial][size=3]Monday and Tuesday - This pattern remaining very similar right though until Tuesday when the precipitation should slowly fade away, so dry for Northern Alps. Some moderate precipitation is likely at times over Southern parts of Switzerland and Austria, but the concentration remains over parts of Italy. Large precipitation totals are likely over much of Northern Italy with some very snowfalls above 1800m or so, with much of the precipitation falling as snow above 1400m, especially Sunday and Monday.

[size=3][font=arial]Wednesday – Mostly dry to start however showers developing into the afternoon, snow above 1200m to the east, 2000m to the west. [/font][/size]

[size=3][font=arial]Thursday and Friday A lot of uncertainty but the current trend is for patchy precipitation over Thursday, dry Friday[/font][/size]

[size=3][font=arial]Looking at Snow-forecast [/font], it suggests over 1m over snow over arts of Northern Italy, over next 6 days, possibly a lot more in places. [/size]

Thanks Julian. A very interesting week coming up and you've done a great job at summarising what snowforecast.com describe as a "notoriously difficult" weather set-up with which to forecast with accuracy for the Alps.
