Smoke from wildfires in Canada and northern Minnesota moved into southern Wisconsin on Thursday, bringing advisories through noon Friday that may be extended for some parts of the state.
Dane and other counties in south-central Wisconsin are under an “unhealthy for all groups” advisory, counties to the east are under a “very unhealthy for all groups” advisory, and counties to the west are under “unhealthy for sensitive groups” and “moderate air quality” advisories.
