Pittsburgh is waking to mostly clear skies and temperatures around 59 degrees Sunday morning, with a sunny and dry afternoon ahead. The high should reach about 80 degrees, giving outdoor plans a clean break after the region’s recent run of unsettled weather.

Sunny Sunday And Labor Day

Northeast winds of 5 to 9 mph will keep Sunday comfortable as temperatures climb through the afternoon. Skies stay mostly clear Sunday night, with a low near 58 degrees. Monday looks just as cooperative for Labor Day, with sunshine, light east winds and a high near 81.

Heat Builds By Midweek

The quiet pattern lasts through Tuesday, when Pittsburgh should see mostly sunny skies and a high near 85 degrees. Wednesday turns warmer still, with a high near 88 and southwest winds reaching 7 to 17 mph. The National Weather Service says the warming trend will precede the next cold front.

Storms Return Wednesday Night

Showers and thunderstorms become likely after 8 p.m. Wednesday, with a 60% chance of precipitation and a low around 70. Thursday could start with rain showers before 8 a.m., followed by additional showers and thunderstorms during the day, with another 60% rain chance and a high near 80.

Thursday night brings a lingering 40% chance of showers or storms before skies turn mostly cloudy. The forecast then improves again Friday and Saturday, with mostly sunny conditions and highs near 78 and 82 degrees, respectively. The updated outlook builds on Saturday’s forecast by extending the focus into next week’s heat and storm timing.
