Wilmington, OH – Hot and humid conditions will continue across much of Ohio this week, with the most uncomfortable weather expected Wednesday and Thursday as heat index values approach or exceed the upper 90s.
According to the National Weather Service in Wilmington, humidity combined with high temperatures will produce peak heat index values in the mid-90s to near 100 degrees across much of southwest, central and west-central Ohio, as well as portions of northern Kentucky and southeast Indiana.
Forecasters say Wednesday and Thursday will be the hottest days of the week, with cities including Columbus, Dayton, Cincinnati, Wilmington, Springfield, Chillicothe and Portsmouth expected to experience afternoon heat index values ranging from the upper 90s to around 100 degrees.
Even though heat index values may trend slightly lower later this week, the National Weather Service cautions that the effects of prolonged heat are cumulative. Those without access to air conditioning, including older adults, young children and people working outdoors, may become increasingly vulnerable after several consecutive days of hot weather.
Residents are encouraged to stay hydrated, limit strenuous outdoor activity during the hottest part of the afternoon, wear lightweight clothing and check on neighbors who may be at greater risk of heat-related illness.
While the heat remains the primary concern through Thursday, forecast guidance suggests daily chances for showers and thunderstorms will increase later this week into the weekend, bringing periods of unsettled weather along with slightly cooler temperatures.
The National Weather Service recommends continuing to monitor local forecasts for updated heat information and any weather advisories that may be issued.
