His thermometer says the dew point is 11 degrees. When I was training to be a AC and refrigeration tech I remember that due to latent heat of vaporization the air temperature can’t fall below the dew point due since a small amount of heat is generated in the process and that maintains the temperature. I’m being honest when I say my brain never fully understood that science and still don’t even today but I do remember it’s at the dew point is when fog and frost come join the party.
In this case if a Artic front was pushing in with lower dew points yet then it could have gotten even colder. I just said a whole lot of words and yet still didn’t make any sense.

How much colder? Why didn't you take another shot showing it?
