PITTSBURGH, Pa. – After a mild start to the week, Western Pennsylvania settles into a classic Fall rhythm of cool mornings, sunny afternoons, and clear, crisp nights through Thursday. The pattern will hold for several days before a round of showers moves in by the weekend.
According to the National Weather Service in Pittsburgh, skies remain mostly sunny Tuesday and Wednesday with highs in the upper 60s to low 70s. Light north winds will bring a refreshing drop in humidity, while overnight lows fall into the upper 30s and low 40s — cool enough for a jacket at sunrise. By Thursday, high pressure centered over the Ohio Valley ensures continued sunshine and calm air.
Residents across Allegheny, Beaver, and Washington Counties can expect excellent outdoor conditions for mid-October. School events, yard work, and fall festivals will all benefit from the stable weather. However, gardeners should prepare for a chill late Wednesday and Thursday nights, when some outlying valleys may flirt with patchy frost.
Drivers along I-79, I-376, and the Pennsylvania Turnpike will experience dry pavement and excellent visibility all week. Winds stay light and steady, and no major travel delays are anticipated before Friday evening.
By Saturday, a developing front from the west will reintroduce clouds and scattered rain, marking a quick shift back to typical late-October variability. Until then, the region enjoys several picture-perfect Fall days — ideal for hiking, football, and scenic drives through western Pennsylvania’s changing foliage.
