Sunday gives us a brief chance at some clear air with a strong cold front predicted to come through the area. That weather change could push out the current pollution accumulations. We should see PM2.5 levels at Very Unhealthy after midnight, but those levels should be falling into Unhealthy around sunrise. If the clearing is going to happen, we should see levels falling through Unhealthy for Sensitive Groups and Moderate by late morning. Pollution levels should stabilize some through the afternoon before moving up again in the evening.
