The National Weather Service issued a severe thunderstorm warning for parts of western Jefferson County, in addition to New Albany and Corydon in Southern Indiana, until 3:30 p.m. on June 28. Wind up to 60 miles per hour and quarter-sized hail were possible, according to the warning. Thunder and lightning were apparent in Louisville.

Forecasters say isolated thunderstorm cells could become strong enough to produce small hail and wind gusts that could topple trees and power lines.
