A strong cold front will push across the Ohio Valley on Sunday and fire a line of strong thunderstorms.
A warm, humid air mass in place will allow thunderstorms to become strong, with the main threat being strong wind gusts and heavy rainfall.
According to AccuWeather Meteorologist Josh Searles, "There will be an abundance of moisture for storms to feed off of when they move through; therefore, posing the risk for localized flash flooding."
"A few storms will produce winds strong enough to bring down trees and power lines," according to AccuWeather Meteorologist Michael Doll.
The combination of strong winds and torrential downpours could lead to localized power outages.
A line of showers and thunderstorms are expected to develop from central Michigan to central Indiana during the afternoon hours and move eastward into the early evening.
Cities at risk for a strong thunderstorm include Lansing and Detroit, Michigan; Toledo, Ohio; and Fort Wayne and Indianapolis, Indiana.
Heavy rain could lead to poor visibility at times for those traveling across interstates 65, 69, 70, 80, 90 and 94.
Storms are expected to weaken quickly during the evening hours before reaching Louisville, Cincinnati and Columbus, Ohio.

As the cold front moves through on Sunday night, a much different air mass will build in to begin the workweek.
"There will be breezy conditions behind the cold front on Monday, especially in Michigan and northern Indiana," Searles said.
Cooler air will also build across the region behind this storm system to begin the workweek. Daytime high temperatures will run about 5-10 degrees below average, despite abundant sunshine. Places across northern Michigan may fail to get out of the 60s.
