Pittsburgh, PA – Morning sunlight cuts through a thin haze over the Monongahela Valley as western Pennsylvania starts another calm, crisp day. But the still air won’t last. A developing system will bring breezy warmth midweek before a soggy — and potentially chilly — weekend settles in.
According to the National Weather Service in Pittsburgh, highs will climb to near 65°F Wednesday under partly sunny skies before winds strengthen from the south. A few light showers could develop during the afternoon, with a 40% chance of rain spreading east. Thursday briefly clears and cools, setting up the region for a wetter, colder pattern by Friday.
Rain likely begins Friday afternoon and lasts into early Saturday, bringing up to half an inch of moisture and damp roadways for commuters along I-79 and I-376. The chill deepens through the weekend as highs slip into the 50s and lows drop near freezing by Sunday night. That drop may create the first rain-to-snow mix of the season in higher elevations east of the city, especially in Fayette and Westmoreland counties.
For residents planning early Veterans Day events or outdoor projects, Friday’s system could bring gusty winds and wet conditions. The weekend gradually clears but remains cool, offering a brief glimpse of the early-winter pattern expected to strengthen later this month.
After weeks of mild weather, this transition marks the first real taste of what could become a colder, snowier November for western Pennsylvania.
