Predicted high temperatures and poor air quality have the Michigan Department of Environmental Quality (MDEQ) issuing an "Air Action Day" alert Thursday.

The National Weather Service (NWS) forecasts tomorrow's daytime high could reach 97, under mostly sunny skies. 

According to the MDEQ release, "ozone concentrations in the Mississippi Valley have already reached USG (unhealthy for sensitive groups) levels" and that air mass is headed toward Michigan. Cleaner winds from the west could mean improved air quality, the release indicated, but the potential for unsafe levels of ozone led officials to issue the alert. 

People and businesses are encouraged to avoid these activities tomorrow:

• Refueling vehicles or topping off when refueling
• Using gasoline-powered lawn equipment
• Using charcoal lighting fluid

Everyone is encouraged to car pool, use their bicycles or walk, and delay or combine errands when possible.

Active children and adults, and persons with respiratory diseases such as asthma, should limit prolonged outdoor exertion, the MDEQ advises.
