The high for today will reach near 97 degrees with sunny skies and light winds, according to the National Weather Service in Wilmington, which issued a heat advisory from noon to 8 p.m. today due to a prolonged period of dangerously hot conditions with the heat index value, or “feels like” temperature, as high as 100 degrees.

An air quality alert also is in effect, issued by the Miami Valley Regional Planning Commission and Regional Air Pollution Control Agency for Clark, Darke, Greene, Miami, Montgomery and Preble counties, and by the Southwest Ohio Air Quality Agency for Butler and Warren counties. Today’s conditions are favorable for ground-level ozone, or smog, to form.
The air quality index forecast is 100 to 101 for today. Any reading of 101 or higher is considered “unhealthy for sensitive groups.” Older adults, children and anyone with respiratory diseases should cut back prolonged and heavy exertion. If spending time outside, take more breaks and do less strenuous activities.
People are encouraged to do the following to reduce ground-level ozone:
- Avoid driving if possible. If not, combine errands or delay them until the Air Quality Alert is lifted. While driving, avoid excessive idling, especially at drive-thru windows.
- Refuel vehicles after 8 p.m., or wait until the alert is over. Make sure your gas cap is on tightly to avoid letting gas fumes escape.
- Limit the use of gasoline-powered equipment around the home, such as lawn mowers, chainsaws, power trimmers and shredders.
- Mow lawns in the evening when sunlight is not as strong and smog is less likely to form.
