Overview
- Forecast models now favor a westerly, Atlantic flow through the week with successive fronts, though a late-season cold snap remains a low-probability risk.
- Météo-France keeps Finistère, Morbihan and Ille-et-Vilaine on orange vigilance for floods, citing saturated soils and the likelihood of further river rises.
- Gusts of roughly 60–90 km/h are expected on the Channel and Atlantic coasts, with a possible gale on Thursday and blustery conditions again Friday.
- Temperatures will stay milder than a polar outbreak, around 9–10°C in Paris and near 15°C in parts of the south, ending talk of −10°C in the capital.
- Snow will accumulate across the massifs, with about 20 cm on the Vosges, Jura and Massif Central and locally more than 50 cm on higher ranges.
