Although it may look like it, this is not snow we are getting today. Today’s weather forecast was for freezing fog and snow mist. Freezing fog occurs when liquid fog droplets freeze to surfaces, forming white soft or hard rime. This is very common on mountain tops which are exposed to low clouds. It is equivalent to freezing rain, and essentially the same as the ice that forms inside a freezer which is not of the “frostless” or “frost-free” type. The term “freezing fog” may also refer to fog where water vapor is super-cooled, filling the air with small ice crystals similar to very light snow. It seems to make the fog “tangible”, as if one could “grab a handful”. Snow mist is frozen ice crystals. Semantics, I know, but they didn’t call it snow. If you look closely at what has fallen, it does have a different appearance than normal snow.
