56d9dcaadd490_Alps4Mar.thumb.JPG.fa83856
The clock has ticked on and all of a sudden, we have moved into Spring, and you would think that things may start warming up. However the weather has not been that mild, whit plenty of snow above 1500m, while at lower resorts there has rain one day, and snow the next. However colder in recent days, with more general snow to lower levels.

Currently there a is a cool NW flow over the Alps, with low pressure to the north of the Alps.

Charts - Saturday to Tuesday
A NW flow seems likely over the weekend, but switching round to an Easterly by Monday and generally unsettled for the most part with low pressure centred over Italy.

Avoriaz has had a great amount of snow the past few days with the base depth, which has been stuck at 140cm for several weeks, jumping to 165 cm. The good news is that it looks to me like the prospect of a very mild SW air flow for next week is diminishing by the day and this mornings GFS has an icy NE air flow re-established across the continent by 19th...just in time for the European Gay Ski Week! :D
