Columbus, Ohio – Severe storms could rapidly intensify across Ohio Thursday night, with the most dangerous conditions arriving during the late evening hours when many residents are asleep.
According to the National Weather Service in Wilmington, storms will develop along a cold front and push northwest to southeast between 8 p.m. Thursday and 4 a.m. Friday. The highest severe risk, including an enhanced threat level, is focused north and west of Dayton, where damaging wind gusts, large hail, and isolated tornadoes are most likely.
Communities along and north of the I-70 corridor, including Dayton, Sidney, and Celina, face the greatest risk for stronger storms beginning as early as 9 p.m. Farther south, including Cincinnati, Wilmington, and Portsmouth, storms are expected closer to midnight through 3 a.m., bringing heavy rain and a lower but still present severe threat.
Localized flooding is also a concern, especially along and north of I-70, where repeated downpours could overwhelm drainage systems. Urban areas like Columbus and Dayton may see ponding on roads and reduced visibility during the overnight commute.
Residents should charge devices, enable weather alerts, and identify a safe shelter location before going to bed. Avoid overnight travel if possible, as conditions may deteriorate quickly with little warning.
Storm intensity is expected to weaken toward early Friday morning, but additional watches or warnings could be issued as the system approaches.
