Right before we went to film the Sentry in Ste. Clair, we decided to hear the Thunderbolts at the Suncor plant across the river in Canada as coincidentally, they test every Monday, and we happened to be there on a Monday. The place we setup at was a little park thats right on the water, and has perfect view of the refinery. It was really windy as we were literally feet away from the water. It took us a while to find the Thunderbolt that was closest to Michigan, but we did find it. Only 1 stand alone video has been made of it in 2018 and it had broken solenoids and now, a broken rotator. The weird police sirens you were hearing are the plant's Selectatones which surprisingly were able to be heard across the water.
💠The Suncor Refinery test their sirens every Monday at 12:30PM.💠
