Friday is starting gray and groggy in Pittsburgh, with low clouds, fog, and mist dragging morning temperatures into the mid‑60s and cutting visibility to around three miles. Skies stay mostly cloudy for much of the day, and the high should land near 81°F with a light west breeze. If you are heading out early, expect a sticky commute and patchy fog that hangs around until mid‑morning.
Tonight: Thunderstorms Target The Evening Hours
Late Friday evening (after 8 p.m. on June 26), the chance of rain climbs quickly, with showers and thunderstorms likely overnight and the best shot at storms between about 8 and 11 p.m. The overnight rain chance sits near 80%. According to the National Weather Service, bands of storms could drop locally heavy rain, with new rainfall totals of about a tenth to a quarter of an inch and higher amounts where storms linger. Ponding and localized flooding may pop up in poor‑drainage spots, and while winds stay generally light, gusts can kick up around stronger storms.
Saturday: Soggy Start, Storm Chances Hang On
Saturday, June 27, keeps the unsettled pattern going, with showers and thunderstorms remaining possible, especially before late morning. The high should be close to 80°F. A stalled boundary overhead will act like a conveyor belt for repeated rounds of showers. Forecast guidance has nudged the heaviest rain axis a bit farther south, but there is still enough support for moderate to heavy rain at times, which could cause minor flooding in low‑lying neighborhoods. Plan on a wet drive early and occasional downpours scattered through the day.
Next Week: Heat Cranks Up In A Hurry
Temperatures jump sharply as the new week starts. Monday, June 29, is expected to top out near 90°F, Tuesday, June 30, around 95°F, and Wednesday, July 1, could push into the upper 90s. With humidity building back in, heat index values around town may reach roughly 100 to 105°F on Tuesday and Wednesday, which raises heat‑related risks for older adults and people working outdoors. Forecasters are keeping an eye on what could become a stretch of hot, humid days that will make outdoor plans uncomfortable and, for vulnerable residents, potentially dangerous.
What To Watch And Where To Cool Off
In the short term, keep the rain gear close and give yourself extra travel time tonight and Saturday. Any heavier downpour can quickly trigger brief flooding and slow traffic. Looking ahead to the heat, stay hydrated, avoid strenuous outdoor work during the mid‑afternoon peak and check on neighbors or family who might not have air conditioning. The City of Pittsburgh lists public pools, spray parks, and other places to cool off across the city.
There are no watches or warnings posted this morning, but conditions can change fast, especially with tonight’s storms in the mix, so keep a weather app handy and keep an eye out for developing cells. Updates will follow if any watches, warnings or flood advisories are issued. For the latest official forecast details, check in with the National Weather Service Pittsburgh office.
