Weather in the mountains
A high-pressure system will persist over the Alps, bringing warm air masses of subtropical origin.
Conditions in the mountains will remain good, even though the sky will no longer be clear. During the day, sunshine may be intermittently obscured by high clouds. Towards the evening, cumulus clouds are likely to develop further, leading to an increased likelihood of thunderstorms.
Mountain weather tomorrow
The Alps will be affected by masses of warm and unstable air masses.
From the early hours of the morning, clouds will dominate, bringing showers and thunderstorms. Later on, the weather will be sunny at times. However, the unstable atmospheric conditions will encourage the development of localised heat-related thunderstorms.
