Pennsylvania — A sharp bite fills the air across western Pennsylvania this morning. The cold stings exposed skin, and exhaust hangs low over quiet streets.
Temperatures started near 11 degrees in Pittsburgh, with wind chills dipping below zero at times. Skies remain mostly clear early, but winter weather is lining up quickly. Clouds increase today as a system approaches from the west.
By later today, snow showers become more likely, possibly mixing briefly with rain during warmer moments. Highs struggle to reach the upper 30s. Even light snow could create slick spots on bridges and untreated roads. Use caution if commuting or running errands.
Colder air pours in behind the system tonight and Thursday. Daytime highs fall into the 30s, then the 20s by Friday. Winds stay brisk, keeping it feeling colder than the thermometer suggests. Frostbite becomes a concern during extended outdoor exposure.
The weekend brings the most impact. Saturday stays bitterly cold, with highs near 14 degrees. Snow becomes increasingly likely Saturday night into Sunday, with accumulating snow possible. While amounts remain uncertain, any snowfall combined with deep cold raises the risk of icy roads and flash freezing.
Sunday remains wintry, with snow likely at times and highs only near 21 degrees. Travel conditions may deteriorate quickly after sunset. Plan extra time and keep an emergency kit in your vehicle.
Looking ahead, the 6–10 day outlook shows below-normal temperatures holding firm across the eastern U.S. next week. Arctic air remains locked in, while the West warms significantly. Additional snow chances could follow as storm tracks stay active.
