General

At the weekend, the Alpine region will be on the front of a low pressure zone over north-west Europe in a moderate south-westerly current. On Saturday evening and during the night to Sunday, a low pressure system over the Benelux countries will bring more humid air to the north-west half of Switzerland in particular. After a brief period of easing, Switzerland will again be under the influence of a new low over Brittany on Sunday evening and humid and unstable stratified air will flow towards us. On Monday, the cold front of the low-pressure system finally reaches our country.

Saturday, 14 h Grindelwald-Interlaken

1-3/8 Base 2500?

Thermals
Weak due to snow and wet conditions, later moderate. However, there will be more clouds later on, which will slow down the thermals again...

Wind
Grindelwald is protected from the strong SW wind. The higher and the further west, the stronger the wind. This can be seen clearly in the wind charts.
