CLEVELAND - The storm that moved through Ohio late Wednesday and early Thursday has been declared a bow echo/"low end" derecho by the National Weather Service.
Gregory Carbin, a meteorologist with the Storm Prediction Center in Norman, Oklahoma, confirms to WKYC Chief Meteorologist Betsy Kling the event will be classified as a derecho after the storm traveled over 400 miles in 6 hours during its peak intensity early Thursday morning.
Widespread severe thunderstorms over the Midwest last night became organized into a squall line over Indiana before midnight and then accelerated east across Ohio, Pennsylvania and New Jersey through Thursday morning.
Carbin says the average forward spead of the line of storms was 47 m.p.h. The most significant damage appears to have occurred during the late evening across parts of Indiana.
While a few significant wind reports in excess of 70 m.p.h. occurrred, the lack of higher wind speeds and gusts along the entire track of the bow echo kept this event on the lower end of derecho criteria.
Derechoes are typically rare events and only occur every few years. These fast move, large cluster of thunderstorms must travel at least 240 miles and have winds of at least 58 m.p.h., while many can have wind gusts in excess of 100 m.p.h.
