Pittsburgh, Pennsylvania – An Extreme Cold Warning remains in effect across western Pennsylvania as dangerously low wind chills threaten health and travel this weekend.
According to the National Weather Service in Pittsburgh, wind chills as low as 25 degrees below zero are expected from 1 a.m. Saturday through 10 a.m. Sunday, creating hazardous conditions across a wide multi-county region.
The warning includes higher elevations of Butler, Clarion, Jefferson, Armstrong, Indiana, Fayette, and Preston counties, as well as surrounding areas in northern West Virginia. Cities and communities affected include Butler, Clarion, Punxsutawney, Kittanning, Indiana, Uniontown, Grove City, and Connellsville, among others.
Forecasters warn that exposure to these conditions can cause frostbite in as little as 30 minutes on uncovered skin. Prolonged exposure may also lead to hypothermia, particularly for individuals without adequate cold-weather protection.
The extreme cold may also impact overnight and early morning travel, especially along major routes such as Interstate 79, U.S. Route 422, U.S. Route 119, and Interstate 80, where wind exposure is higher in open and elevated areas. Motorists are urged to prepare for potential vehicle issues related to cold temperatures, including battery failure.
Residents are advised to dress in layers, including hats, gloves, and face coverings, and to limit time outdoors whenever possible. Officials also encourage checking on vulnerable individuals, including older adults and those without reliable heating.
This cold outbreak may be especially disruptive for early-morning commuters, outdoor workers, and students, as the most dangerous conditions are expected during overnight and pre-dawn hours.
The National Weather Service recommends staying informed through local alerts and taking precautions until temperatures and wind chills improve late Sunday morning.
