Pennsylvania shifts gears heading into Sunday as damp roads, gray skies, and lingering cold set the stage for changing travel conditions. Pavement stays dark and wet through the day, but the bigger concern arrives later, when temperatures trend back toward freezing and winter reasserts itself.
According to the National Weather Service, clouds hold firm Sunday with rain developing during the afternoon and evening. Highs rise into the low 40s across the Philadelphia region, warm enough to melt leftover ice but not warm enough to dismiss winter hazards. Rain becomes more widespread by nightfall, especially along the I-95 corridor.
For drivers across Philadelphia, Sunday travel may start quietly but deteriorate after sunset. Roads that appear merely wet could refreeze late, particularly on bridges, overpasses, and less-traveled streets. Plan extra time if returning home Sunday night or heading out for end-of-year trips. Slow speeds and steady braking remain key.
Sunday night lows dip toward the mid-30s, with colder air waiting just beyond. As rain tapers early Monday, temperatures begin to fall again. Any lingering moisture could turn slick before dawn, raising the risk for flash freezing as the new workweek begins.
Monday brings a brief break from winter chill, with highs pushing toward the upper 50s amid periods of rain. That warmth does not last. Cooler air settles back in Tuesday, keeping highs near the mid-30s and restoring a winter feel across the region.
Looking ahead, New Year’s Eve on Wednesday appears dry but brisk, with temperatures hovering near the upper 30s. Winter patterns remain active as 2026 approaches. Traveling Sunday night or early next week? Tell us what conditions look like where you are.
