Germany’s Weather Whiplash: Fog Now, Near-20°C Midweek, Possible Polar Flip by Weekend

Key models now split on a late-week polar plunge with a risk of upland snow after the brief thaw.

Overview

  • Dense fog, low clouds and drizzle mark the start of the week, with the DWD warning of poor visibility in spots such as Cologne and parts of NRW.
  • The national forecaster expects sunnier, milder conditions by Wednesday and Thursday, with widespread double-digit highs.
  • Meteorologists say Sahara-influenced air could push temperatures locally toward 20°C, especially near the Alps and in parts of western Germany.
  • ECMWF simulations indicate a sharp cold surge from Friday into the weekend, with a steep drop aloft and potential snowfall for higher terrain like the Sauerland, Harz and Alpine regions around November 15–16.
  • The GFS also signals a cooler, wetter turn but favors rain in lowlands, leaving the extent and elevation of any weekend snow uncertain.
