Storms rolling through Central and Eastern Kentucky on Friday night dumped more than 3 inches of rain on parts of Lexington.
WKYT-TV Chief Meteorologist Chris Bailey said downtown Lexington got the brunt of the rainfall, which resulted in some street flooding.
Frequent lightning strikes caused transformer fires and knocked out traffic signals. The weather also disrupted the kickoff of high school football season.
Bailey said there was significant flooding in some parts of Eastern Kentucky, particularly Prestonsburg and Ashland. "Minor high water" was reported in Scott and Franklin counties, he said.
The National Weather Service said scattered storms are expected throughout the weekend and into next week because of a "moist, unstable atmosphere." Some of the storms could bring gusty winds, torrential rainfall and dangerous lightning.
"Humidity is just off the charts," Bailey said. "It's basically a tropical atmosphere."
