Overview
- Temperatures near 20–23°C persisted Thursday and Friday along the Upper Rhine and Alpine fringes under a southwest flow linked to low ‘Pepe’ and local Föhn effects.
- The weather turns markedly colder from the weekend as polar air advances, with the DWD warning of slippery roads and urging winter readiness.
- Forecasts call for significant snow in higher terrain: roughly 5–10 cm in central Mittelgebirge within hours and locally over 10 cm in parts of the Alps.
- Nighttime frost is expected early next week across many areas, with daytime highs often in the single digits as the cold air mass settles.
- Model guidance diverges on the extent and path of the cold surge (ECMWF vs GFS), leaving the timing and likelihood of any lowland snow in the coming week as an evolving, low-confidence scenario.
