Overview
- Early‑week sunshine, which held on Monday, pushed afternoon highs widely into the 20–26°C range in many regions.
- The incoming upper‑level cold low, known in France as a goutte froide, is forecast to arrive Tuesday from the southwest and set off localized thunderstorms from the Pyrenees toward the Alps and along parts of the Atlantic coast.
- Under a blocking high, the north and east should stay drier through midweek, while Provence is expected to remain largely sunny with inland highs around 24–26°C through Sunday, according to Météo‑France in Aix.
- Forecasts point to thicker cloud on Saturday and more widespread rain on Sunday for the May Day weekend, with temperatures easing by a few degrees.
- Rainfall looks modest and uneven this week, with modelled totals such as about 21 mm in Ariège and 13 mm near Bordeaux, and forecasters note the exact late‑week path of the cold low adds uncertainty.
