Pennsylvania – Wet pavement glistens under low clouds as temperatures hover near freezing. The calm feel this morning may be short-lived as a developing system raises concerns for ice during peak post-Christmas travel.
Across western Pennsylvania, including the Pittsburgh metro, the National Weather Service is highlighting the potential for freezing rain on Friday. A low-pressure system moving through the Ohio Valley may introduce a brief but impactful period of icy precipitation before transitioning to rain.
Temperatures climb into the mid-40s Friday afternoon, but colder air near the surface could allow rain and snow to mix, especially early. Forecasters warn freezing rain may develop in pockets, creating slick conditions on bridges, ramps, and untreated roads.
Travel impacts could be most noticeable Friday morning through early afternoon. Reduced traction is possible along I-79, I-376, I-279, and Route 28, particularly during higher traffic periods. Even light ice can quickly lead to hazardous driving.
By Friday night, precipitation shifts mainly to rain as temperatures stay above freezing. Rain remains likely into Saturday, with highs near 45 degrees. While ice concerns diminish, roads stay wet and visibility may drop at times.
Saturday night remains mostly cloudy and cooler. Lows dip into the mid-30s, allowing moisture to linger on roadways. Sunday brings steadier rain, with highs rising near 59 degrees. Rain continues through Sunday night, increasing the risk of ponding on roads.
Looking ahead to Monday, rain may mix with snow later in the day as colder air filters back in. Breezy conditions follow, and temperatures trend downward into early next week.
Drivers should plan extra time Friday. Slow down on elevated roadways. Monitor updated forecasts closely. Winter weather may evolve quickly as December travel continues across the region.
