About 2,500 Lexington customers lost power in Thursday night's storm, but service was restored to almost all of them by Friday morning.
Kentucky Utilities spokesman Cliff Feltham said about 10 homes were still without power shortly after 8 a.m. Friday.
Fayette County got the brunt of the storm, but about 150 homes in Franklin County and about 100 in Madison County lost power, Feltham said.
Meanwhile, Lexington firefighters made at least 21 runs overnight related to the weather, Battalion Chief Joe Best said.
He said the calls covered a variety of problems, including suspected lightning, strikes downed power lines and transformer fires, Best said. Some fire alarms were set off by the storm. No lightning strikes on homes were confirmed, Best said.
Feltham blamed the power outages mainly on wind blowing limbs into power lines. Some lightning strikes also contributed, he said.
More storms are possible Friday afternoon, and Feltham said repair crews will be ready.
"Some of our folks are getting some sleep right now because many of them were up into the wee hours," he said.
