Forest Hill city hall employees were sent home early Friday afternoon because the air conditioning isn't working.
Temperatures at city hall were 90 degrees, said Venus Wehle, a spokeswoman for the city.
"We didn't want anyone up here getting sick because of the heat," she said.
Wehle said that when employees arrived for work Friday morning, there must have been a power surge because of the storm. Phones were flashing, and some computers had to be reset, she said.
City hall will reopen at 7 a.m. Monday.
