Clear and calm evening, ideal for all outdoor activities. A few cloudy banks lingering longer in the Simplon region and the Saas Valley. On Tuesday, the beautiful summer weather will continue, with sunshine often at its highs in the lowlands (at the most, fine veils in the afternoon). Cumulus developing in the mountains during the day, which may locally lead to a thunderstorm cell in the Gran San Bernardo region and towards the Gotthard massif. Almost no risk of thunderstorms elsewhere. Hot. Temperatures expected in the Rhône plain: lows 10 to 16° from the Upper Valais to the edge of Lake Geneva, highs 29 to 31° from the Chablais to the central Valais. In the stations around 1500m: lows 9 to 12°, highs 23 to 24°. On the summits: 10/20° at 2000m, 5/11° 3000m. Isotherm of 0 degree around 4500 meters of altitude. Moderate breezes in the valleys during the day. Weak wind of north-western tendency in high mountain. (MeteoNews, June 14th, 4 pm)
Trends for the weekend
Weekend in Valais
The weekend of June 19-20 is expected to be very hot again on Saturday, with a tendency for thunderstorms in the mountains in the afternoon and evening, more rarely over the lowland areas of the central Valais. The evolution for Sunday is still not very reliable, with probably more chaotic skies and thunderstorms that could affect all regions.
