Pittsburgh, PA – Fall weather is taking center stage this Columbus Day week across western Pennsylvania, bringing sunshine, mild temperatures, and a midweek cooldown. After a cloudy start Monday, skies are expected to clear with highs near 69°F before dropping into the upper 40s tonight.
According to the National Weather Service, Tuesday will be the week’s warmest day, reaching 73°F under clear skies — ideal for fall drives along I-376 or visits to Pittsburgh’s local pumpkin patches. However, a noticeable chill will follow midweek as cooler Canadian air settles in, bringing highs only in the upper 60s by Wednesday and Thursday.
Residents can expect calm, dry weather through Friday, making it a great stretch for outdoor decorating or leaf-viewing trips across Allegheny County. Winds will shift north at 5 to 10 mph midweek, delivering crisp mornings with lows dipping into the upper 30s by Thursday night — a reminder that the first frost of the season isn’t far off.
By Saturday, showers are expected to return, with rain chances rising to 60% through the weekend. Sunday remains unsettled, as forecasters anticipate scattered showers but continued mild daytime temperatures near 70°F.
