A fast moving compact bow echo that developed along Interstate 64 in southwestern Indiana continued moving east, through Jefferson, Shelby, Franklin, Scott and Fayette Counties in Kentucky. Louisville was especially hard hit. Widespread winds ranging from 55 to 70 mph downed many trees and power lines across the northern and central portions of the city. Widespread road closures and power outages to more than 100,000 customers occurred. Electricity was not restored in some neighborhoods for several days, delaying the start of the school year by two days for 98,000 public school students. Farther east across the Bluegrass Region, a narrow path of damage continued across northern Woodford County and into Lexington.
