DAVENPORT, Iowa — The Quad Cities woke up to a new layer of beautiful frost on Monday, January 4, 2021.
Much of this frost carries a daggered-looking edge to it, and is known as "rime ice."
As StormTrack 8 meteorologist Andrew Stutzke explains, rime ice happens when fog is present with temperatures below freezing.
Here's how it works: Tiny (still liquid) water droplets are suspended in the air. They turn to ice only once they are disturbed by another force, and run into something like a tree or fence post. At that point they freeze instantly, creating the sharp or daggered-looking edge on the frost.
