Pennsylvania – Low clouds hang over the rivers this morning as mist softens city lights and rain taps steadily on pavement. The air feels damp and chilly, not biting yet, but cold enough to demand caution. Winter remains subtle for now, though changes are lining up as holiday travel approaches.
According to the National Weather Service in Pittsburgh, rain continues through much of the day with temperatures rising into the upper 40s. Winds stay light to moderate, helping keep conditions mild by late-December standards. Accumulation is not a concern, but steady rainfall keeps roads slick across Allegheny County.
Across western Pennsylvania, including Pittsburgh and surrounding suburbs, clouds linger into midweek. Wednesday brings a brief break with partial sunshine and highs in the mid-40s. That pause allows roads to dry and travel to improve along I-376, I-279, and the Parkway West.
Christmas Day stays unsettled but mild, with scattered rain possible and highs near 50. For travelers, conditions remain manageable, though damp roads continue. Attention then shifts to the end of the week, when colder air slowly filters back in.
By Friday, rain redevelops with a stronger system. Temperatures remain near 50 during the day, but colder air arrives later. As readings fall Friday night, rain could mix with snow before tapering off. Even limited snow combined with falling temperatures raises the risk of black ice, especially on bridges and elevated roadways.
Drivers returning home after Christmas should plan for changing conditions after sunset. Wet pavement can freeze quickly once temperatures drop, increasing crash risk during overnight and early morning hours.
Winter patterns remain active heading into the final week of December. Additional advisories are possible as timing becomes clearer.
