Overview
- Forecasts, which flag Thursday as the wettest day, call for widespread rain across most regions with only brief breaks near the Mediterranean.
- Temperatures run 5 to 7 C below mid‑May norms, with 10 to 16 C by day and brief ground frosts possible at dawn in some plains and valleys.
- Snow returns to the Alps and Pyrenees, with the snow line around 1,200 to 1,700 meters and light accumulations at mid‑elevation.
- Southern and Mediterranean areas stay brighter but very windy, with mistral and tramontane gusts near 50 to 70 km/h and up to 80 km/h in exposed spots.
- Following Friday’s unsettled showers, Saturday offers more sunny breaks, then Sunday splits with a new Atlantic front wetting the west and north as the southeast dries, before a warmer 20 to 25 C trend early next week.
