Weather in the mountains
The air pressure is beginning to rise; the air masses are moist.
Patches of high valley fog may cause reduced visibility in some areas in the morning; otherwise, there will be plenty of sunshine to start with. During the day, patches of cloud, some of which will be quite thick, will move through over summit level.
Mountain weather tomorrow
High-altitude winds will be blowing from the south-west, bringing moist and unstable air masses towards the Alps.
Air masses will become more humid and may at times reduce visibility due to fog or low cloud. Isolated thunderstorms, alternating with sunny spells, are likely as early as this morning. From the afternoon onwards, these conditions will become more widespread. Winds will be very strong at times, blowing from the south-west.
