The photo above shows a foggy morning in the Meuse Valley at as seen from the Sept Meuses viewpoint, Rivière, Belgium. Such fog is common in the Meuse Valley from October to January. This is referred to as a radiation, evaporation, or valley fog. It’s likely that clear skies during the overnight period here permitted the ground to cool to the dew point temperature, resulting in a net heat loss and the formation of fog. The densest fog formed in the valley bottom, where the lowest temperatures were reached. Photo taken on November 13, 2022.
