The National Weather Service has issued a wind advisory for much of southwestern Pennsylvania and northern West Virginia, saying people can expect gusts of up to 40 or 50 miles per hour Saturday.
The advisory, which begins at 1 a.m. and remains in effect until 1 p.m., warns that low pressure moving toward the Great Lakes will likely pull a cold front through the Ohio River Valley, possibly downing tree limbs or power lines and making it difficult to drive.
The advisory affects Allegheny, Armstrong, Butler, Indiana, Washington, Greene, Westmoreland, Fayette, Monongalia, Mercer and Venango counties, among others.
Previous predictions that thunderstorms might drop large hail had not materialized as of 9:30 p.m. and meteorologists said that threat appeared to have passed.
