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

The EPA's Air Quality Index can tell you whether breathing outside air can be harmful. Here's how to read the scale to plan accordingly in Michigan.

Officials warn southeast Michigan residents to be careful outdoors Tuesday because of expected high ozone pollution levels.

The extended forecast suggests unsettled weather midweek, with rain probabilities ranging from 30% to 60%. There is some uncertainty about the exact timing and placement of the rain, but meteorologists anticipate widespread cloud cover and precipitation potential Wednesday through Thursday.

On July 15, rain and thunderstorms are expected in southern Michigan and in the Upper Peninsula. Then, more rain and thunderstorms are forecast statewide on July 16. Widespread haze is included in the forecast for northern Michigan as the Canadian wildfire smoke moves over Michigan.

An air quality alert remains in effect across the state of Michigan through Monday. But will the smoke continue to linger? ()
