A powerful spring storm knocked down trees and power lines and left thousands without electricity in southeastern Wisconsin.

We Energies worked to restore power to thousands. As many as 17,000 customers were without service at the peak of the storm, but utility crews made significant progress in restoring power by Wednesday morning.

WTMJ radio reports the storm hit Milwaukee, Waukesha, Dodge and Jefferson counties the hardest. One wind gust measured 68 miles per hour in Oconomowoc.
