Overview

• A northwest feed of moist North Sea air under temperature inversions is trapping fog and low cloud in valleys while hills and the Alps see more sun.
• The DWD warns of morning fog with road visibility in places dropping below about 150 meters.
• Daytime highs mostly reach 13–18 C, including around 15–17 C in the north, with only patchy drizzle and weak winds.
• Nights cool to near freezing locally with possible ground frost, especially in sheltered lowlands of Bavaria, Saxony and parts of Brandenburg.
• Meteorologists note the blocking high, locally dubbed “Sieglinde,” persists this week, and any polar‑vortex‑driven return of Atlantic fronts around 20 October is only a model signal.
