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.
