12:45 AM: Moderate wood smoke continues.
6:30 AM: A very faint smokiness remains in the air. It is just enough to tell the air is not fresh.
3:15 PM: Light grass smoke at this time. Somebody is burning yard waste. I am home enjoying a vacation. I wonder how much grass burning takes place when I am not around to notice it.
5:00 PM: No smoke. 85 degrees, sunny, a nice summer day.
7:00 PM: No wood smoke.
8:00 PM: No wood smoke.
9:10 PM: Light wood smoke at this time. There had to be wood smoke tonight. If the air isn't smoky, it is uncharacteristic of North St. Paul, MN, the most polluted city in the world.
9:45 PM: Faint wood smoke.
10:30 PM: The air is mostly clear. Only a very faint trace of smoke remains.

Compared to yesterday's horrific wood smoke, we got off easy tonight. There was a little burning grass in the afternoon and air pollution that never exceeded the level of light. Yesterday, the wood smoke was extremely heavy. Light air pollution is about as good as it gets in North St. Paul.
