The humidity will make it feel more like upper 90s to perhaps even around 100 degrees (36 to 38 degrees Celsius). Actual temperatures will reach the mid 90s (34 to 35 degrees Celsius), with not much breeze to help. Accordingly, the National Weather Service has issued a Heat Advisory for today. Highs again in the mid 90s (35 degrees Celsius), with the heat index possibly exceeding 100 degrees (38 degrees Celsius) during the afternoons. But highs should drop into the upper 80s (31 degrees Celsius), with more manageable humidityand lows Saturday night dropping into the mid 60s (19 degrees Celsius).

The National Weather Service has issued an Air Quality Alert for today, so this means it's our first Ozone Action Day of the season. The ozone layer, which is about ten miles up in the stratosphere, is GOOD ozone, because it filters some of the sun's ultraviolet radiation. However, there is also low-level ozone, which is caused when emissions created by cars, coal power plants, etc. So, what can we do to help curb that low-level ozone? If you have respiratory problems, or your health is significantly compromised by other health issues, do not overexert yourself on Ozone Action Days.

DETROIT Its a hot holiday weekend in Michigan, but air quality for much of the state is at a moderate level of concern. The U.S. AQI (Air Quality Index) is how the EPA reports air quality. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality. Air quality is acceptable.
