Satellite picture of Terra showing an almost cloud free Benelux. The white plumes are areas covered by snow, most of them are situated on the leeward side of industrial zones or cities, in this case with prevailing easterlies to be found on the western side. The red arrow points the location of Steenokkerzeel where most of the shots below were taken. (Source satpicture: Image courtesy of MODIS Rapid Response Project at NASA/GSFC)

Observed sounding of Beauvechain (near Brussels) showing a very pronounced inversion of more then 14 °C between the surface and 257 meter height. In the lower dozen meters, the air was still saturated. But the subsidence inversion descended resulting the remaining Stratus clouds were soon cleared. Legend: red line = temperature, blue line = dewpoint. (Source sounding: Belgocontrol)

21/12/2007 1110. Previous day gave persisting fog, low Stratus and sometimes light flurries of industrial snow. When the sun came out, opportunity was taken to make some photographs, this one shows a row of rimed poplar trees.
