You may want to make sure your air conditioning is working. Columbus, and a sizable chunk of the nation, is in for a scorcher of a week with heat index values as high as 105 degrees possible on July 24 and 25, according to the National Weather Service in Wilmington.
Daytime high will climb into the 90s starting on Wednesday and remain there at least until Monday, with a brief dip into the 80s on Saturday, according to an NWS forecast. That’s just the air temperature. Humidity will make those temperatures feel much warmer.
If you’re headed to the Ohio State Fair this week, you might want to hydrate and make sure you know a few places to beat the heat. But don’t forget your umbrella.
Those hot temperatures won’t be accompanied by clear skies as showers and thunderstorms are in the Columbus forecast Thursday through Sunday.
What were the hottest July days in Columbus?
While the heat index this week will make central Ohio feel more like the Louisiana bayoy, Columbus will get nowhere near the hottest recorded air temperature for July, according to the NWS.
Two July days are among the hottest on record.
They were July 14, 1936, and July 21, 1934, which both reached highs of 106 degrees.
