Today will be hot and mostly sunny, with highs around 87 degrees, according to the National Weather Service in Wilmington.

There will be a few more clouds overnight but otherwise will be mostly clear as temperatures fall to around 66 degrees.

On Wednesday, the day will be mostly sunny with clouds gradually increasing, along with a chance of showers and thunderstorms starting in the afternoon that will continue through the night.

There will be an Air Quality Alert in effect for Butler and Warren counties on Wednesday, issued by the Southwest Ohio Air Quality Agency. The agency said it expects the air quality to be unhealthy for sensitive groups, such as children, elderly adults and people with cardiac or respiratory diseases. It encouraged the public, especially those groups, to limit time spent outdoors.

During the alert, the agency encouraged residents to help reduce pollution creation by carpooling, taking the bus, riding a bike or walking to work; refueling after 6 p.m.; avoiding idling their vehicles; avoid using gas-powered lawn equipment; avoid using oil-based paints and stains; and never burn leaves or other yard trimmings.

Some storms may be severe Wednesday afternoon and Wednesday night with possible damaging winds and large hail as the primary threats. A tornado also is possible.

It also will be hot, with highs around 90 degrees and heat index values as high as 100 degrees. It will still be warm overnight, with lows around 74 degrees.

The chance of thunderstorms will fall away after sunrise on Thursday, with a lingering slight chance of showers in the morning, afternoon and evening. Clouds will gradually decrease during the day, for sunny skies in the afternoon and mostly clear skies overnight.

It will be hot again Thursday, with highs around 93 degrees and lows around 73 degrees. The heat index may approach 100 to 105 possible on Thursday and Friday.
