NASA’s Earth Observatory had some interesting pictures this week about localized snow in the Netherlands.  They think it was caused by changes in fog over small areas to snow due to the seeding of ice crystals, which changed the liquid fog droplets into ice crystals that consolidated into snowflakes.  In the areas affected 1-2 inches of snow was seen, turning the fields white while leaving nearby areas bare.  You can see the pictures and read about it at https://earthobservatory.nasa.gov/IOTD/view.php?id=89560&src=eoa-iotd.
