Minnesota can be really beautiful, even when it's minus 5 degrees.

Sea smoke happens when cold air (it was really cold in Duluth Wednesday morning) passes over warmer water. It heats up rapidly, which induces "convection currents" that rise in the air, carrying moisture upwards from the water, Encyclopedia.com explains.
This moisture quickly condenses in the cold surrounding air, creating columns of rising water vapor. It is typically seen around Arctic landmasses, such as parts of Norway, Greenland and Canada.
The same thing can happen with rivers, when the air is 50 degrees or more colder than the water, the website notes.
