Pittsburgh, Pennsylvania – A widespread Arctic cold pattern is expected to return to the western Mid-Atlantic beginning Thursday, bringing dangerously cold temperatures, subzero wind chills, and the potential for snow through the following Wednesday.
According to the National Weather Service Climate Prediction Center, western portions of Pennsylvania, West Virginia, and parts of western and southwestern Virginia are favored to experience below-normal temperatures during the Jan. 15–21 period as Arctic air settles across the Appalachians and Upper Ohio Valley. While overall precipitation is expected to remain near seasonal levels, persistent cold will allow snow and ice to linger, increasing travel and safety concerns.
In western Pennsylvania, including Pittsburgh, Butler, Washington, and Beaver counties, overnight wind chills could dip below zero at times. Even light snow could lead to slick conditions along Interstate 79, Interstate 376, and Interstate 70, especially during morning and evening commutes. Prolonged cold may also raise concerns for frozen pipes and increased heating demand.
Across West Virginia, colder air will be amplified by elevation. Northern and central areas such as Morgantown, Clarksburg, Elkins, and Beckley face an elevated risk for icy roads and hazardous travel on mountain routes, including Interstate 79, U.S. 33, and U.S. 219. Snowfall may be locally heavier in higher terrain, with limited melting between systems.
Farther south into western Virginia, including the Roanoke Valley, New River Valley, and portions of the Virginia Highlands, temperatures are expected to remain well below seasonal averages. Repeated overnight freezing could lead to black ice on Interstate 81 and secondary roads, particularly in shaded and elevated areas.
Residents across the region are urged to prepare by checking heating systems, insulating exposed plumbing, and keeping winter emergency kits in vehicles. Limiting outdoor exposure during overnight and early morning hours will be critical if wind chill advisories are issued.
Cold-related alerts and possible winter weather advisories may expand as confidence increases. Additional updates are expected as the Arctic pattern becomes more firmly established across the western Mid-Atlantic late next week.
