Philadelphia, Pennsylvania – A late-winter arctic outbreak is forecast to bring dangerous cold and subzero wind chills to Pennsylvania from Friday through Monday, increasing the risk of frozen pipes, heating system strain, and cold-related emergencies across the state.
According to the National Weather Service and NOAA’s Climate Prediction Center, a surge of arctic air will move into the Northeast, Mid-Atlantic, and parts of the Midwest beginning Friday, Feb. 6. The coldest conditions are expected through Sunday night into Monday, with wind chills falling below zero in northern and western Pennsylvania and into the single digits or lower across the southeast.
Forecast outlooks indicate much-below-normal temperatures persisting into early next week. Gusty winds are expected to intensify the cold, creating conditions that may lead to frostbite on exposed skin in as little as 10 to 30 minutes, especially overnight and during early morning hours.
The extended deep freeze raises concerns for household plumbing, particularly in older homes and rowhouses common throughout Pennsylvania. Pipes located in basements, crawl spaces, exterior walls, and unheated garages are most vulnerable during consecutive days below freezing. Regionally, Lake Erie is now nearly 100% frozen, highlighting the strength and persistence of the cold air mass affecting the eastern United States.
State and local officials urge residents to insulate exposed pipes, seal drafts around doors and windows, and maintain consistent indoor heat, even when away from home. Letting faucets drip slightly and opening cabinet doors can help reduce the risk of frozen pipes. Authorities caution against using open flames, propane heaters, or torches indoors to thaw pipes due to serious fire and carbon monoxide hazards.
Cold weather safety guidance also advises limiting time outdoors, covering exposed skin, and ensuring pets and livestock have adequate shelter. Additional cold weather advisories or warnings may be issued as the weekend approaches.
