Precipitation will tend to become less frequent in the afternoon, with some clear spells developing from the west towards the very end of the day. The lull will arrive later in Upper Valais. It will be very cool for the season. Expected temperatures in the Rhône Valley: minimums 10 to 12°, maximums 12 to 13°. In resorts around 1500m: minimums 4 to 6°, maximums 5 to 7°.
