Pennsylvania – Cold air bites early across the Delaware Valley this MLK Day, with brittle pavement, stiff winds, and temperatures struggling to recover. Breath hangs in the air, car doors creak open, and shaded sidewalks stay icy longer than expected. Even where sunshine breaks through, melting is brief before refreezing sets up slick conditions again.
According to the National Weather Service in Philadelphia, highs reach the mid-30s today, with wind chills closer to the teens this morning. Gusty west winds funnel through city streets, making it feel colder along I-95, I-76, and exposed bridges. Tonight, temperatures fall back into the mid-teens, increasing the risk of black ice where daytime melting occurs.
Tuesday stays bright but colder, with highs only in the low 20s. By Wednesday, temperatures rebound toward the mid-30s, a key transition point. That warming trend may allow moisture to return, raising concern for snow or a wintry mix later in the week if cold air holds nearby. Meteorologists are now tracking a broader pattern shift that favors increased precipitation across the Mid-Atlantic as Arctic air presses east.
For drivers, the biggest issue is timing. Roads may look dry by midday, then turn slick again after sunset. Plan extra travel time, especially during early mornings and evenings. Pedestrians should watch for frozen patches near curbs and crosswalks. Keep winter layers handy and avoid rushing across icy surfaces.
Looking farther out, NOAA’s 6–10 day outlook suggests colder-than-normal air lingering across Pennsylvania, with precipitation chances increasing into late week. Additional weather alerts may be issued as midweek approaches.
