Thunderstorm Wind in Morrow County, Ohio

Trees downed and metal roof damaged in Mount Gilead.

Northern Ohio was within the warm sector during the morning of the 11th through early evening of the 13th as the region remained along the northwestern flank of the Bermuda-Azores subtropical high pressure ridge. Simultaneously, a very slow-moving cold front approached northern Ohio from the Upper Midwest as multiple surface lows moved northeastward along the front. Ahead of the front, six distinct rounds of severe thunderstorms with damaging wind gusts affected northern Ohio between the early morning of the 11th and early evening of the 13th. These storms utilized moderate to strong MUCAPE, moderate to strong DCAPE, and primarily moderate to strong effective bulk shear.
