Weather in the mountains
The Alps will be affected by a high-pressure system bringing very warm air.
On the main ridge, the day will start off cloudy, whilst further south it will be very sunny to begin with. During the day, a few cumulus clouds will form, but the likelihood of showers will remain low.
Mountain weather tomorrow
The high-pressure system will weaken temporarily, and the air near the ground will become slightly more humid.
High valley fog or clouds may restrict visibility in places on some mountains, but away from these areas, sunshine will prevail. As the day progresses, some cumulus clouds will develop, and a few thunderstorms are also expected in the afternoon.
