It's pretty hard to see with all of this fog in the Treasure Valley. So when is it going to make an exit?
An inversion has entered the Gem state and that is one of the reasons we are experiencing such low visibility in the Treasure Valley. When cool conditions are mixed with high humidity, you get fog. The National Weather Service issued a dense fog advisory until at least tomorrow for Boise and until Thursday for the Nampa and Caldwell regions.
A lot of this is expected to last until this coming weekend. Things will clear out after Saturday and there is a light chance of a rain-snow mix going into Sunday. Following is another high-pressure ridge that clears things out again with temperatures consistently into the mid to low 40's.
If you live in West Treasure Valley, do prepare for consistent fog until the weekend and please drive safely at night.
