Good morning. It's Wednesday, November 6th. I'm Crystal Orren, with your Mid-Columbia news from The Tri-City Herald. The air stagnation advisory for the Tri-Cities has been extended until at least noon on Friday as still air continues to keep pollution trapped near the ground. Air quality is rated as unhealthy for sensitive groups, including children and the elderly. Today should be sunny with a high of about 54 degrees and an overnight low around the freezing point.
