Prepare for poor air quality from Canadian wildfire smoke and rising temperatures today, with rain and thunderstorms expected to return midweek.

Wildfire smoke from Canada will be moving into Michigan from Saturday to Monday, creating poor air quality across the state.

Unhealthy air has invaded Minnesota, Wisconsin and North Dakota early this week as a new round of wildfire smoke from Canada has wafted into the region, choking out areas as far south as Chicago and Detroit.
