More late night burning in North St. Paul, MN. This happens often and is why we can never open the windows before bedtime.
3:00 PM: Faint to light wood smoke coming in on the wind. 54 degrees, cloudy, windy.
6:30 PM: No smoke. 61 degrees, sunny.
8:30 PM: There is a light something in the air that smells like motor vehicle exhaust fumes. I don't know what it is. It could be exhaust fumes or somebody could be burning waste.
10:30 PM: A light pollutant of some type that smells like exhaust fumes continues.
11:45 PM: Faint wood smoke. I don't know why anyone would start using a fireplace at this late hour on a Sunday night. My guess is that someone has a bonfire going or is preparing to burn waste. There is someone around somewhere who likes burning waste on Sunday nights.
