Overview
- Cold air from Scandinavia moves in late Sunday into Monday, turning the recent 20-degree days into a wet, much colder pattern.
- The DWD expects snow to start around 1,000 meters, with the snow line locally sinking toward 500 meters and 10 to 20 centimeters in Alpine and windward high terrain.
- Northern shores could see Tuesday’s lake-effect setup produce narrow, intense snow showers that vary sharply over short distances.
- Daytime highs settle near 1 to 7 degrees through midweek, with nights near or below freezing and an increased risk of morning frost and slick conditions.
- Model guidance diverges on late‑week snowfall extent, prompting cautions against broad deep-snow claims, while Saharan dust aloft may be washed out in patchy “blood rain.”
