Pittsburgh, PA — Western Pennsylvania is set for a mostly dry, cool stretch this weekend, with just a small chance of an isolated shower north of I-80 on Saturday afternoon.

Saturday starts off with a mix of clouds. Expect partly to mostly cloudy skies, daytime highs in the low to mid-50s, and overnight lows slipping into the low to mid-30s. A brief sprinkle is possible later in the day for communities north of Pittsburgh—think Clarion and DuBois—but most areas should stay dry.

By Sunday, brighter skies take over. Look for mostly sunny conditions with highs climbing into the mid to upper 50s. Light winds will add to the comfort, making it a pleasant day across the Allegheny Valley and nearby counties.

Heading into early next week, forecasters aren’t tracking any major weather systems. The region remains in a steady fall pattern—mild afternoons paired with crisp, chilly nights.
