Pennsylvania — Breath turns white instantly, sidewalks creak under frozen boots, and exposed skin stings within minutes. An intense Arctic air mass holds firm across western Pennsylvania, keeping Pittsburgh locked in dangerous cold early this morning.
A Cold Weather Advisory remains in effect through late morning as wind chills plunge as low as 15 degrees below zero. Actual temperatures hover near zero, while light northwest winds sharpen the bite. Even short trips outside can become risky without proper layers.
Clouds linger today with only a slight chance of flurries. Highs struggle to reach the upper teens, and wind chills stay well below zero through much of the day. Drivers should expect slick patches on untreated roads, especially on bridges and elevated ramps like I-376 and Route 28. Flash freezing remains a concern where moisture refreezes quickly.
Tonight stays brutally cold. Temperatures dip back into the single digits, and cold stress increases for anyone outdoors too long. Pipes, especially in older homes, remain vulnerable. Pets should stay inside, and outdoor water sources need protection.
By Monday, sunshine breaks through, offering little warmth. Highs climb into the upper 20s, still well below normal. A weak disturbance Monday night into Tuesday brings a slight chance of light snow, though impacts appear minor for now. Even light accumulation could reduce visibility during the Tuesday commute.
Midweek stays cold but quieter. Highs hover near 30 Tuesday, then fall back into the mid-20s Wednesday. Another snow chance emerges late Thursday into Friday as temperatures remain locked below freezing, signaling continued winter hazards into early February.
Meteorologists continue tracking long-range trends as cold air dominates much of the eastern U.S. Dress in layers, limit time outside, and check on vulnerable neighbors.
