With smokey conditions likely worsening throughout Aug. 3, an extended air quality advisory is possible, according to the National Weather Service.

An air quality advisory is in effect until at least noon Monday for all of Wisconsin because of the Canadian wildfire smoke. The heaviest smoke is expected across eastern Wisconsin Sunday, while lighter impacts are more likely for western counties.

Smoke from widespread Canadian wildfires has spread into the US, particularly affecting the Midwest and Northeast, leading to hazy conditions.
