On Thursday and Friday, the mediocre conditions will continue, with cloudy skies and areas of showers possible at any time of the day, but more frequent near the higher ground, where a thunderclap cannot be ruled out. Clear skies are also expected over lowland areas. Temperatures remaining cool for the season, between 16 and 18°C at low altitudes in the afternoons.
For the Whitsun weekend (including Monday), there will be more sunshine over the lowlands, but the atmosphere will remain unstable and a few showers may reappear in the afternoons. There is a greater risk of showers - sometimes thundery - over the higher ground. Maximum temperatures around 20° and 12° at around 1500 m.Nicolas Borgognon; Tuesday, 14. May 2024, 16 Uhr
