— Did you notice the frost looking a little unusual, with a ‘spiky’ appearance this morning? That's because it wasn't your typical frost.
The frost was created by fog, called ‘freezing fog.’ Freezing fog develops when the water droplets within the fog touch something that is below 32 degrees.
The droplets immediately freeze on contact, with each droplet freezing upon the last. This creates a jagged or dagger appearance.

Don’t eat the snow! A study, published in 2016, claimed that eating snow is potentially dangerous, particularly in urban areas.
Dr. Parisa Ariya, a professor at McGill University in Canada, told The Huffington Post that snow in cities can absorb toxic and carcinogenic pollutants and that the snow itself combining with those pollutants can lead to even more dangerous compounds being released.
"Snowflakes are ice particles with various types of surfaces, including several active sites, that can absorb various gaseous or particulate pollutants," she said.
Ariya, who led the study, said she did not "wish to be alarmist," but "as a mother who is an atmospheric physical chemist, I definitely do not suggest my young kids eat snow in urban areas in general."
The study examined how snow interacts with pollutants from car exhaust in the air. Findings showed that snow pulled pollutants like benzene, ethylbenzene, toluene and xylenes from the air. The amount of pollutants concentrated in the snow increased dramatically.
