Runs used: ECMWF IFS, Nov 11 12 UTC run · ECMWF AIFS, Nov 11 18 UTC run · NOAA GFS, Nov 11 18 UTC run · DWD ICON-EU, Nov 11 18 UTC run. Updated Nov 12, 03:21 AM. Snow as 10 cm for every 10 mm of water (a rule of thumb).
Why several models?
Each weather centre runs its own model of the atmosphere, and no single one is always right. When the models agree, the forecast is more certain; when they disagree, the weather is harder to call, and it is worth watching the newer runs. The Lab's Forecast mode shows each model's maps, and Compare models sets them side by side for any place.
