Pittsburgh is starting Friday with a cool 64 degrees and humid air, but patchy fog could linger through the early morning commute. The haze should burn off quickly, giving way to mostly sunny skies and a high near 81.

Fog Fades Before A Dry Weekend

Fog is expected before 9 a.m., then north winds of 1 to 7 mph will help bring in drier air. Rain chances are minimal Friday, with only a 4% probability, and no watches, warnings or advisories are posted for the area, according to the National Weather Service in Pittsburgh.

Friday night will be mostly clear and notably cooler, with a low near 57. Saturday looks like the weekend’s best bet for outdoor plans: sunny, light winds and a high near 83, followed by a partly cloudy night near 62.

Sunday Starts The Late-Summer Warm-Up

Sunday stays mostly sunny and reaches about 86, with just a 1% rain chance. The dry stretch is a marked change from Thursday’s storm setup detailed in Hoodline’s earlier forecast, making for an easier final weekend of August across the city.

Heat Builds Before Midweek Storm Chances

Temperatures climb into the upper 80s Monday, with a high near 89, then peak near 91 Tuesday as humidity returns. A slight chance of showers begins Tuesday night, while Wednesday brings a 50% chance of showers and thunderstorms during a still-warm day near 90.

Wednesday night could stay unsettled with another 50% rain chance, and Thursday keeps a lower chance of showers and thunderstorms with a high near 87. For now, the forecast favors dry plans through the weekend and a weather-aware eye on the middle of next week.
