Europe is entering a much more dynamic phase between Wednesday afternoon and Thursday evening. France is already dealing with widespread showers and thunderstorms, while Germany, Switzerland and Austria still hold on to unusually mild air in places. The dividing line moves east overnight as a cold front becomes the dominant feature.
Germany reaches 20 to 25°C in many central and southern areas on Wednesday, while northern areas are cooler. Austria still sees 18 to 26°C, with foehn-enhanced warmth in the east and Alpine valleys. Switzerland is also mild on the northern side of the Alps, while rain is already more frequent south of the main Alpine ridge.
Thursday turns cooler across central Europe
During the night, rain spreads east across Germany and the Alpine region. Morning temperatures across much of central Europe generally fall into the 6 to 15°C range, while Mediterranean coasts remain milder. By Thursday afternoon, Germany is mostly at 14 to 20°C and Austria at 14 to 22°C, although eastern Austria may briefly remain much warmer ahead of the front.
France turns distinctly cooler behind the disturbance. Météo-France expects highs of 14 to 17°C across most regions, 17 to 19°C in the southwest and 20 to 25°C close to the Mediterranean. Winds strengthen behind the front, particularly on coasts, exposed hills and in the mountains.
Alps become the key snow zone
The western and northwestern Alps are the main snow focus. The Alpine forecast expects around 20 to 30 cm of fresh snow in high elevations from the Mont Blanc area toward the Glarus Alps by Thursday, while the snow line falls toward roughly 2000 metres along the northern pre-Alps by evening. In the eastern Alps, the snow line stays higher for longer before dropping more sharply later.
Travel impacts through Thursday are therefore more likely to come from heavy rain, thunderstorms and wind at lower elevations, while winter conditions increasingly affect high Alpine passes, exposed ridges and glacier areas. The sharpest cooling reaches the mountains first.
