Smoke from the wildfires is expected to move out by Tuesday but could return as the fires continue to burn across Canada.

The Wisconsin DNR says air quality levels have improved from “unhealthy” to moderate, but that doesn’t mean the risk is over.

The Michigan Air Quality Division said as smoke from Canadian wildfires continues to threaten the upper Midwest, "monitors in the western (Upper Peninsula) showed a large increase surface concentrations, during Tuesday, as smoke mixed down, which sent PM-2.5 concentrations soaring into the Unhealthy and higher range."
