Pittsburgh is waking up to clear skies, sticky air and temperatures near 70 degrees Friday morning, but the calm will not last all day. Fog may linger into late morning before scattered showers and thunderstorms develop, with a high near 82.
Fog Gives Way To Afternoon Storm Chances
Areas of fog are possible before 11 a.m., followed by a growing chance of showers and thunderstorms from late morning through the afternoon. The rain chance reaches about 30%, with new rainfall generally expected to stay below a tenth of an inch.
The National Weather Service says winds should remain light, generally from the east at 1 to 5 mph. No watches, warnings or advisories are posted for Pennsylvania, Ohio or West Virginia in the current forecast.
Saturday Looks Like The Outdoor Window
Friday night should turn partly cloudy and cooler, with a low around 66. Saturday offers the best weather break of the weekend: mostly sunny skies, light winds and a high near 86.
That break is temporary. Showers and thunderstorms could arrive Saturday night, especially after 8 p.m., with a 60% chance of precipitation and rainfall totals between a tenth and a quarter-inch possible.
Sunday Brings The Biggest Weather Concern
Showers and thunderstorms are likely Sunday, with an 80% chance of rain, a high near 86 and another round of storms Sunday night. Rainfall during the day could reach a quarter- to half-inch, while stronger storms may bring gusty winds and locally heavy downpours.
The weather service's latest discussion identifies Sunday as the period with the greatest potential for more widespread flooding and severe weather across the region. The exact timing and location of the strongest storms remain uncertain, so outdoor plans may need a backup option.
Cooler, Drier Weather Arrives Later
Monday stays partly sunny with a high near 83 and a 30% chance of showers or thunderstorms. Tuesday should bring patchy morning fog followed by sunshine and a high near 82, while Wednesday looks sunny and warm near 84.
Another chance of showers and thunderstorms returns Wednesday night into Thursday, when temperatures should remain in the low-to-mid 80s. For Pittsburgh, the week ahead looks less like one long heat wave and more like a series of warm breaks between storm systems.
