The NWSR also warns that dense, patchy fog is expected to make a return tonight as well, possibly causing more of the “rime ice” pictured and described below.

“What’s the difference between hoar frost and rime ice? To build upon our previous post: Hoar frost occurs when WATER VAPOR directly crystalizes on surfaces (process of deposition = vapor –> solid state). Rime ice is technically supercooled LIQUID drops (which compose the freezing fog) freezing on contact with a sub-freezing surface.”
