Noticed snow fog in parts of Johnson County on the way to work this morning. It was rising through the trees in some of the valleys, and then re-freezing on the branches making some beautiful, glass-like formations on every twig. Wish I could have stopped to get some photos, but as usual I was in a big hurry. Anyone know what conditions it takes to make this stuff? - Tried finding something about it online but couldn't locate anything. Really beautiful!
