Overview

• Northern France begins the week with calm, sunny weather and temperatures near seasonal norms, contrasting sharply with unsettled conditions in the south.
• A polar cold drop continues to drive showers and thunderstorms in southern regions, particularly from the Alps to the Pyrénées and Corsica.
• Météo-France forecasts a gradual stabilization in the south by Tuesday, while the north faces risks of white frost in the mornings under cooler conditions.
• By midweek, the cold drop revives instability in southern regions, with localized showers and thunderstorms expected across the Alps, Auvergne, and Pyrénées.
• Recent extreme temperature swings, including a 17°C drop in Strasbourg and 12°C in Paris over two days, highlight climate change's role in amplifying weather volatility.
