OHIO — A second wave of severe thunderstorms is expected to redevelop across a large portion of Ohio on Wednesday afternoon, April 15, 2026, with the greatest threat period running from 2:00 PM through 8:00 PM and the first four hours of that window carrying the highest risk. Forecasters at WTOL 11 issued a Weather Impact Alert for the region, warning that strong gusty winds and isolated tornadoes are both possible as storm lines redevelop following a morning lull in activity.
A veteran meteorologist with 15 years of experience at WTOL 11 described this as by far the busiest start to a spring severe weather season ever covered, underscoring the exceptional and relentless nature of the ongoing outbreak affecting the region.

This second wave scenario is particularly dangerous because residents may let their guard down during the quieter morning hours, only to be caught off guard when conditions rapidly deteriorate again later in the day.
The main timing window of 2:00 PM to 8:00 PM covers the peak heating hours of the afternoon, which combined with an unstable atmosphere creates ideal fuel for storm development across the region.
Greatest Severe Risk Concentrated in Central and Northern Ohio

The risk gradient extended westward into Indiana near Fort Wayne and covered additional Ohio communities including Lima, Van Wert, Defiance, Ottawa, Bryan, Wauseon, Bowling Green, and Adrian…
