Pittsburgh woke to cool, clear skies Saturday morning (May 16, 2026), with temperatures in the upper 40s to around 50°F. The cool start will not last long. Temperatures are expected to jump into the low 80s this afternoon as south winds pick up. Scattered showers and a few thunderstorms are possible later in the day, so outdoor plans should stay a little flexible.
Afternoon Storms Possible
Scattered showers and a few thunderstorms are most likely between about 2 p.m. and 5 p.m., with the greatest chances southeast of the city and an overall precipitation probability near 50%. Most neighborhoods should see less than a tenth of an inch of rain unless a stronger cell passes directly overhead, and gusts could reach roughly 20 to 25 mph in heavier showers. This timing and wind potential are highlighted in the local forecast from the National Weather Service.
Evening Commute And Flight Concerns
Showers and thunderstorms may linger into the evening commute, with lowering ceilings and pockets of heavier rain that could slow traffic and leave bridges and ramps slick. If you have evening travel, check transit alerts and carrier notices, since localized delays are possible. A wind-whipping storm preview earlier this week flagged the potential for commute headaches.
Heat Spike Early Next Week
Temperatures climb sharply on Monday, May 18, with highs near 90 to 91°F, and another hot day is expected on Tuesday, May 19. Wednesday again looks more unsettled, with higher rain chances returning. While officials say Heat Advisory criteria, meaning dangerous heat indices, are unlikely, the much-warmer-than-normal stretch could still affect older adults, young children, and people without air conditioning. Allegheny County maintains a list of cooling centers and related resources for relief. See county guidance from Allegheny County for cooling-center information and 2-1-1 assistance.
What To Do
Plan to start the day with a light jacket for the cool morning, but keep an umbrella or rain jacket handy for the afternoon, and a water bottle for the weekend warmth. If you or someone you check on is heat-sensitive, map out cooler indoor hours on Monday and Tuesday and call 2-1-1 if you need help locating a cooling center or other assistance.
