Cloudy and muggy this morning in Pittsburgh. As of 5:40 a.m. EDT Sunday, May 24, 2026, the temperature is about 55°F with a dew point near 54°F and south-southeast breezes. Scattered showers will increase through the day, with the high climbing into the upper 70s and the best chance for storms in the mid-to-late afternoon.
Afternoon And Evening
Scattered rain showers are likely before 2 p.m., then scattered showers and thunderstorms between about 2 p.m. and 5 p.m., with a high near 78°F. The National Weather Service in Pittsburgh says there is roughly a 60% chance of precipitation today, with brief heavy downpours that could drop a tenth to a quarter-inch. Tonight's storms could produce locally higher totals of three quarters to an inch. Patchy fog is also possible after midnight as the air saturates, which may reduce visibility for the Monday morning commute.
Localized Flooding Risk
Although a Flood Watch that ran Saturday has expired, forecasters caution that pockets of heavy rain (mainly south of I-80) could produce urban and small-stream flooding this afternoon and tonight. If you encounter standing water, remember "Turn Around, Don't Drown" and avoid driving through flooded streets. Monitor local updates for any watches or warnings.
Memorial Day Outlook
Memorial Day, Monday, May 25, 2026, should be milder with most neighborhoods reaching around 80°F and only isolated rain chances early in the morning, then mainly cloudy skies afterward. Northwest breezes are expected to ease event organizers' concerns for afternoon plans, though early-morning patchy fog could affect parades and riverfront ceremonies.
What You Should Do
Bring a lightweight raincoat if you have outdoor plans this afternoon and leave extra time for travel. Check the National Weather Service before heading out and consider a dry backup for evening events.
