Several times, since moving to Ashland more than 10 years ago, we have experienced a “fog freeze” where it will get foggy and then the temperature drops to below freezing. The plants and trees turn white until the temperature rises above freezing when the frozen fog that has clung to them melts.

This year the fog freeze has happened at least twice already, including today. Sometimes, if you are lucky, the fog will lift to reveal blue skies. The fog freeze usually melts very soon once blue skies appear so you have to be quick to catch the beauty of the white trees with blue sky background.

I took this photo out the window of my office on the SOU campus.

I’m not sure if this is Rime Frost or Hoar Frost. Does anyone know the difference?
