It was a beautiful spring evening. It was the nicest day we have had in about two weeks. Naturally, the air would be smoky.
4:30 PM: No wood smoke. Partly cloudy, breezy, 70 degrees.
6:00 PM: No wood smoke.
7:00 PM: Faint wood smoke for a few minutes around this time. Somebody was grilling meat with wood. It did not last long or the wind shifted.
8:00 PM: No wood smoke. Fresh air!
9:00 PM: No wood smoke. Fresh air continues.
10:00 PM: A very faint smokiness of some type is in the air. It is not strong enough to determine what it is. The windows will have to be kept closed tonight. As with every night.
10:30 PM: Very faint smokiness continues.
11:35 PM: Light to moderate wood smoke. In this stupid city recreational burning is supposed to stop at 11:00 PM. That is when it tends to really get started. Nobody around us is burning. The burner could be a block or two or more away.
Midnight: Light wood smoke continues.
