CHILLICOTHE, OH – A heat advisory is in effect for Southern Ohio, including Ross and Pickaway Counties, as dangerously high temperatures settle in, starting at noon today, Monday, June 23, 2025, and lasting through at least Wednesday, June 25, according to the National Weather Service. Reported at 11:53 AM EDT, the advisory warns of heat index values potentially reaching up to 104°F, posing significant risks of heat-related illnesses.
Over the next few days, temperatures are expected to climb into the mid-90s, with humidity pushing the “feels like” temperature into the triple digits. Monday and Tuesday are forecasted to be the hottest, with highs possibly nearing 97°F and heat indices around 102-105°F. Wednesday may see a slight dip to the low 90s, but relief remains limited as overnight lows stay in the upper 60s to low 70s, offering little respite. Isolated thunderstorms could emerge by Thursday, though they are unlikely to significantly cool the region.
The prolonged heat and humidity heighten the risk of heat exhaustion and heat stroke, particularly for vulnerable groups like the elderly, children, and those with health conditions. Heat exhaustion symptoms include heavy sweating, weakness, dizziness, nausea, and headache, while heat stroke— a medical emergency—features a body temperature above 103°F, hot dry skin, rapid pulse, and confusion. If these signs appear, move to a shaded or indoor area, cool the person with wet cloths or a fan, and seek immediate medical help.
To stay safe, experts recommend drinking plenty of water (2-4 cups per hour if active), avoiding caffeine and alcohol, and wearing lightweight, light-colored clothing. Limit outdoor activities to early morning or evening, and seek air-conditioned spaces like libraries or cooling centers if needed. Check on at-risk neighbors and never leave pets or people in vehicles, where temperatures can soar rapidly.
Local authorities are opening cooling centers, and residents are urged to prepare as the heat wave persists.
