A severe heat wave is set to hit Ohio this weekend, with dangerously high temperatures and heat index values soaring up to 105°F in many parts of the state, including Columbus, Dayton, and Cincinnati. The National Weather Service (NWS) has issued an Excessive Heat Watch for Sunday afternoon through Tuesday evening, urging residents to take serious precautions to stay safe.
Intense Heat to Begin Sunday Afternoon
According to the NWS in Wilmington, the heat will kick into high gear on Sunday, with sunny skies and temperatures reaching 96°F in Columbus and surrounding areas. With high humidity, the heat index—the “feels like” temperature—will rise to 105°F, creating dangerous conditions, particularly for those without air conditioning or adequate hydration.
Drivers on highways like I-70 and I-71 should be cautious as high temperatures can cause pavement surfaces to exceed 130°F, potentially leading to tire blowouts and engine strain.
Nighttime Will Provide Little Relief
Even after the sun sets, temperatures won’t dip much. Overnight lows will stay in the mid-70s, offering limited relief, especially for those in areas without air conditioning. The combination of high daytime heat and warm nights will add stress to vulnerable populations, including the elderly, children, and anyone with respiratory issues. Emergency managers recommend checking on elderly neighbors to ensure their safety during the heat wave.
Monday and Tuesday: Heat Continues with High Health Risks
The heatwave is expected to persist through Monday and Tuesday, with highs again reaching 96°F each day. The heat index will hover around 105°F, making outdoor activity risky. The NWS advises residents to stay indoors during peak heat hours from 12 p.m. to 5 p.m., stay hydrated, and avoid strenuous physical activity.
What to Expect and How to Stay Safe
For many Ohioans, this heat will be a serious challenge. The NWS warns that high heat, combined with the lack of overnight cooling, will make conditions hazardous.
People are encouraged to avoid outdoor activities during the hottest parts of the day and to take regular breaks if they must be outside. Hydration is key—be sure to drink plenty of fluids, and avoid beverages that dehydrate you, such as alcohol and caffeine.
With the heat expected to persist through Wednesday, residents are advised to continue monitoring local weather reports for updated warnings and advisories.
