Drier conditions are expected to develop Friday morning, with mostly sunny weather expected to push the afternoon high near 82 degrees. The calm start is a brief one, as rain and thunderstorms return Saturday before another storm threat develops Sunday.

The forecast is a notable turn from the stormier midweek pattern described in Hoodline's previous Pittsburgh forecast, but the quiet spell is short-lived. Friday night should turn mostly cloudy, with temperatures falling to around 64 degrees.

Friday Offers Pittsburgh A Sunny Weather Break

Friday afternoon will be mostly sunny with light easterly winds and little chance of rain. The evening should stay dry, making Friday the easiest day for outdoor plans before the weekend turns unsettled.

Saturday Rain Could Bring Localized Flooding

Showers and thunderstorms may begin Saturday morning around 8 a.m., with additional storms possible through the afternoon and evening. The chance of precipitation rises to 70%, and new rainfall could reach between a tenth and a quarter of an inch in the Pittsburgh area.

Heavier downpours could still produce much higher totals, with the National Weather Service warning that swaths of 1 to 2 inches are possible and localized flooding could become a concern, especially south and southeast of the city. Anyone with outdoor plans should have a shelter option ready and avoid driving through water covering a roadway.

Sunday Warms Up As Stronger Storms Enter The Picture

Sunday should be warmer, partly sunny and near 83 degrees, with only a slight chance of showers or thunderstorms during the afternoon. However, forecasters are monitoring the potential for strong to severe storms Sunday afternoon and evening as a cold front crosses the region.

Damaging winds, hail and tornadoes could be possible if the storm system develops as expected, with the greatest concern currently north of Pittsburgh. No watches, warnings or advisories are listed in the current forecast, but the storm outlook may change as the weekend approaches.

Calmer Weather Returns Monday Before Another Warmup

Monday looks mostly sunny with a high near 78, followed by a warmer Tuesday near 85 under mostly sunny skies. Shower and thunderstorm chances increase again Wednesday and become more likely Thursday, when the high should reach about 84 degrees.
