DAYTON, OH - Heat is going to extremes again in southwest Ohio, a week after the region saw one of its warmest and longest hot spells in years.
The National Weather has issued an excessive heat watch for the counties that include Cincinnati and Dayton, and has posted a heat advisory for surrounding counties. Humidity will also be a big factor today.
The weather service office in Wilmington said earlier this week that the eight days that ended Sunday were Dayton's warmest, on average, since 1940. It was Cincinnati's hottest eight-day stretch since 2007.
Organizers of the annual Vectren Dayton Air Show say attendance was down 15 percent amid the weekend's extreme heat and humidity.
A news release says an estimated 65,000 attended the show.
Officials with the air show said Monday that no other major problems were reported, though on Saturday, the show's general manager said that about a dozen people were treated for dehydration or heat exhaustion.
