Philadelphia, Pennsylvania – Slick travel could develop before 8 a.m. Thursday across parts of Pennsylvania as light overnight snow brushes central and northern counties, but temperatures rising 15 to 20 degrees above average will melt most accumulation before the midday commute.

According to the National Weather Service Climate Prediction Center, Pennsylvania falls within a 40 to 50 percent above-normal precipitation zone through Tuesday. That wetter-than-average signal stretches from the Gulf Coast into the Mid-Atlantic and Northeast, increasing the likelihood of multiple systems moving across the state to close out February.

In Philadelphia, where average highs this time of year sit in the low 40s, afternoon temperatures next week may climb into the upper 40s and low 50s along the I-95 corridor. Pittsburgh and areas along I-79 could see brief overnight snow or a rain-snow mix before daytime melting takes hold. In the higher elevations of the Poconos and along I-80, slushy accumulation may linger longer before turning to rain.

The broader outlook favors above-normal temperatures across much of the eastern United States, while cooler air holds over parts of the West. That contrast keeps the jet stream active across the Mid-Atlantic, supporting periodic rounds of precipitation.

Drivers should allow extra travel time during early morning hours, clear storm drains to reduce ponding and monitor PennDOT and local advisories for updates. The milder pattern holds into early next week, though additional systems could still prompt winter weather alerts. Winter is easing, but Pennsylvania is not finished with it yet.
