Pennsylvania – Wet pavement darkens streets across western Pennsylvania this morning as mild air holds briefly, but winter stands ready to flip the switch. Rain arrives later today, then colder air barrels in fast, setting up snow showers, gusty winds, and reduced visibility by Sunday.
According to the National Weather Service in Pittsburgh, rain develops mainly after late afternoon with temperatures climbing into the low 50s. Amounts remain light, yet roads along I-79, I-376, and Route 28 turn slick through the evening. Winds stay modest at first, but conditions deteriorate quickly overnight as colder air rushes in.
By Sunday, rain changes to snow showers, especially after midday. A few heavier snow bursts or squalls are possible. These can briefly reduce visibility and coat roads with a quick accumulation, even if totals stay near an inch. West winds strengthen, gusting up to 40 mph at times, blowing snow across open stretches and bridges.
Drivers should expect rapidly changing conditions Sunday afternoon and evening. One neighborhood may see wet pavement, while another turns slushy within minutes. This setup favors sudden slowdowns and spin-outs, especially on elevated roadways and hills around Allegheny County.
Sunday night stays cold and breezy, with temperatures dropping into the mid-20s. Any moisture refreezes quickly, increasing the risk of black ice for the Monday morning commute. Monday brings partial sunshine but little warmth, with highs near 39 and lingering slick spots early.
The rest of the week remains active. Another round of rain is possible Tuesday night into Wednesday, with colder air trailing behind it. That keeps winter firmly in place across western Pennsylvania.
Plan extra travel time Sunday. Secure loose items ahead of gusty winds. Slow down when snow bursts hit, even if conditions look fine moments earlier.
