Pennsylvania – A crisp, bright start quickly gives way to a dramatic warmup, and drivers should already plan for rain to disrupt travel by Thursday afternoon. Sidewalks feel dry now, but change is building fast across the region.
According to the National Weather Service, temperatures climb from the 50s midweek to near 70°F Thursday. Moisture surges in by early afternoon Thursday, with rain chances rising to 70% and continuing into the evening hours.
Across Philadelphia and into South Jersey, conditions stay calm through Wednesday with increasing clouds. By Thursday after 2 p.m., light rain spreads over Center City, I-95, and the Schuylkill Expressway. Roads turn slick quickly, especially during the evening commute. Expect reduced visibility and slower traffic speeds.
By Friday morning, rain lingers with a 60% chance, especially before 8 a.m. Wet pavement and ponding could slow traffic on I-76, Roosevelt Boulevard, and area bridges. Allow extra time and keep headlights on in steady rain.
Temperatures fall sharply Friday night to near 29°F. Any leftover moisture could refreeze in spots, especially on untreated roads and overpasses. That raises a low-end flash-freeze concern heading into early Saturday.
The weekend brings relief. Sunshine returns Saturday with highs near 45°F, then climbs to the mid-50s Sunday. Early next week trends milder, reinforcing a clear shift toward spring warmth.
If you’re planning travel Thursday afternoon or early Friday, adjust timing now. Conditions may deteriorate quickly after sunset. What are you seeing on your commute today?
