What is ice fog?

Meteorologist Brett Collar breaks down a weather phenomena called Ice

Here in the Miami Valley we see all kinds of weather phenomena, including freezing fog and ice fog. While the two have similar dynamics, they do vary a bit.

Fog that turns to ice upon contact with a solid surface that has a temperature of 32 degrees Fahrenheit or less is known as freezing fog. This often occurs on elevated surfaces such as trees, power lines, bridges and overpasses. 

Ice fog is fog that freezes mid-air, simply because temperatures are so cold. The fog is not able to live long enough as water vapor and touch a solid surface before it crystallizes. 

Ice fog is not something that is often seen, and it only occurs while conditions are very cold and winds are light. The ice fog is noticed as a shimmering fog, often times referred to as frost flakes.
