A complex of thunderstorms, known as a derecho, raced from Indiana and Ohio across the central Appalachians and into the Mid-Atlantic States during the late afternoon and evening hours of June 29th.
The tail end of this complex skirted eastern Kentucky, but an outflow boundary pushed well away from the storms themselves and brought damaging winds well outside of any areas that saw any rain or thunderstorm activity.
The radar imagery below, courtesy of The University Corporation for Atmospheric Research, shows the thunderstorm complex racing across north and northeast Kentucky between 5 pm and 9 pm EDT on Friday June 29th. The outflow boundary, indicated by the narrow band of echoes racing southward, produced wind speeds up to 68 mph causing numerous downed trees and power outages. At one point, up to 63,800 Kentucky Power customers were without power in eastern Kentucky alone.
The damaging winds extended as far south as an Irvine, Hazard to Elkhorn City line before diminishing. There were even reports of blowing dust with the passage of the front and brush fires caused by the downed power lines. All damage reports received by the National Weather Service in Jackson, KY are listed below. Click on the map for an interactive local storm report viewer for June 29th.
