Dry weather this evening and overnight under a partly starry sky, and rather cool temperatures for the time of year. Thursday, some sunny spells in the morning. Otherwise, clouding over and rain arriving at times from the south-west in the afternoon. Precipitation becoming frequent at the end of the day and into the early evening. Rainfall totals could range between 30 and 35 l/m² for the episode in the Chablais and more like 15 to 20 l/m² in the other regions of Valais. Temperatures becoming cool at the end of the day with a snow limit that could sometimes drop down to 2000 m in the evening in the Chablais, 2500 m elsewhere. Forecast temperatures in the Rhône plain: minimums 11 to 14°, maximums 19 to 21°. In the resorts around 1500m: minimums 6 to 8°, maximums 13 to 15°. On the peaks: 6/12° at 2000m, 2/3° at 3000m. Freezing level: 3300 m. Light to moderate breeze during the day in the Rhône plain. Noticeable south-westerly wind in the high mountains (wind gusts sometimes exceeding 55 km/h around 2500m).

Friday, weak post-frontal conditions. Isolated showers cannot be completely ruled out near high ground. Otherwise, changeable weather but with often generous and prolonged sunny spells over lowland areas. Cloud cover tending to linger over the mountains or along high ground. Maximum temperatures between 20 and 23°, 14° at 1500 m. Saturday, forecast still uncertain due to the passage of a warm front currently poorly resolved by the various models. Weather generally partly to fairly sunny with potentially extensive cloudy spells. A few spots of rain cannot be completely ruled out. Maximum temperatures between 23 and 25°, 17° at 1500 m. Sunday, a very sunny interval, under a sky nevertheless crossed by veils of cirrus cloud in the afternoon. Also the development of cumulus clouds over high ground. Maximum temperatures between 25 and 28°, 21° at 1500 m. Monday, morning still sunny, then a probable increase in cloud cover in the afternoon. Rain and thunderstorms expected at the end of the day and into the evening. Forecast still to be confirmed. Maximum temperatures between 26 and 28°, 21° at 1500 m. For the rest of next week, probably weak post-frontal conditions next Tuesday, then a gradual rise in pressure in the second half of the week, resulting in more stable, sunny and summery weather.
