Columbus, Ohio – Dangerous storms are set to roll across central Ohio on Sunday, July 27th, threatening Columbus and surrounding counties with flash flooding and damaging winds. Heat index values will soar dangerously close to 100 degrees by early week, making outdoor plans risky and increasing the potential for power outages and road closures on highways like I-70 and I-71.
According to the National Weather Service in Wilmington, thunderstorms will move through the region Sunday afternoon, with the strongest cells capable of producing localized flooding and winds strong enough to down trees and power lines. The main threats are expected between noon and 9 p.m. Sunday. Emergency officials urge residents to avoid unnecessary travel during severe weather, especially near low-lying areas and flood-prone intersections. If you must travel, never attempt to cross a flooded roadway—turn around, don’t drown.
Sunday’s high will reach near 89°F, with heavy rain possible in the afternoon and evening. Monday and Tuesday will bring sweltering heat, with heat indices approaching 100°F across Columbus, Dayton, and along I-270 and I-71 corridors. Residents should hydrate, avoid strenuous activity, and check on elderly neighbors. Air conditioning is vital as humidity rises and overnight lows stay muggy.
Localized power outages, hazardous travel, and fast-rising creeks are possible. Prepare now: charge devices, secure outdoor items, and have a plan if severe weather strikes overnight.
Storm risks decrease by Tuesday night as cooler, drier air returns midweek. Additional watches or advisories may be issued as conditions evolve.
