This heat has been brutal.  Temperatures within a hair of 100 degrees and heat indexes of over 100.

With much higher humidity and pollution levels it's hard on everybody and is expected to be even a greater threat to sensitive groups of people.  So, the Michigan Department of Environmental Quality has declared today an Air Quality Action Day.

They are urging us to be especially watchful for children, older adults, people with heart disease and those with asthma or other respiratory issues. And, people who are extremely active outdoors are advised to avoid prolonged exertion outdoors.

Those with heart disease or respiratory issues who are involved in sports or other strenuous activities should make sure their conditions are medically managed, the MDEQ says. They also are advised to increase rest periods and switch to activities that allow them to lower their breathing rate.

We're all asked to refrain from using lawn mowers and other gas-powered engines and to wait until dusk to refuel cars and trucks.

There is some weekend relief in sight, but we're going to suffer through at least one more day of intense heat.
