A zone of high pressure has parked itself over the Puget Sound over the past couple weeks, and there have been a lot of cold nights, which have given way to dense fog, which usually burns off by late morning or early afternoon and leaves the sky open and clear, and the cycle repeats itself. I love the fog personally. But the freezing fog is unpleasant on the lungs.
The air mass has become stagnant at the same time, due to thermal inversion and a lack of mixing. So there is a lot of pollution - smoke and particulates - in the air as well. My lungs could use some fresh air.
