“Dense Fog” is actually smoke.

For context I live in an area where summer wildfires are nasty and the smoke is nastier. In the winter there tends to be small fires in the earlier months however according to the DNRC there are no active wildfires within 200 miles of where I live. Now this is day three of a “dense fog” rolling in over the hills into my valley town, and normally I would think nothing of it but when you walk outside there is the distinct smell and burning sensation of smoke not fog. Adding that and the fact that the last three days the “fog” rolls into our town around 8:30AM and is always gone by 12:30PM, yesterday was 33°F with low wind speed and low moisture, the previous day was 29°F and snowing with low wind speed and moderate moisture. I’m no meteorologist but with my experience living where I live this is an oddity and slightly concerning especially with the smell of smoke. Now there was a big inauguration for the new governor yesterday and in a weird situation the fog lifted over capitol hill and suddenly returned after the inauguration, I’d love to claim cosmic coincidence but I have a hard time believing that. I don’t know what’s causing this but I do believe something is going on whether good or bad.
