Pittsburgh woke up Tuesday morning, today, to clear skies and crisp, almost early-fall air, with temperatures in the upper 40s at dawn. It is shaping up to be a mostly sunny, comfortable day, with an afternoon high near 77°F and a light southwest breeze. The quiet stretch will be brief, though, with scattered showers late tonight and a more serious storm setup lining up for late Wednesday into Thursday.
Afternoon Into Tonight
Through this afternoon, skies should stay mostly sunny, with southwest winds of about 2 to 9 mph and highs near 77°F. Clouds build in late Tuesday, and scattered showers with a few thunderstorms are possible between about 1 a.m. and 5 a.m. tomorrow. Overnight lows will dip to around 59°F, and early commuters should be ready for brief, localized downpours in spots, according to NWS Pittsburgh.
Juneteenth And The Weekend
Juneteenth events across downtown, including activities around Point State Park and Market Square, are scheduled for Friday, June 19. Organizers and attendees should note a chance of morning showers before skies trend mostly sunny with a high near 78°F. If you are planning to be outside Friday morning, keep a backup plan in mind and double-check event schedules for any last-minute changes. See VisitPittsburgh for full event details and times.
Late-Week Severe Threat
A stronger low pressure system is expected to move through late Wednesday into Thursday, and forecasters say the setup could support organized thunderstorms capable of producing damaging straight-line winds and isolated tornadoes overnight. Gusts in the stronger cells may reach roughly 30 to 35 mph, and brief heavy downpours of around a quarter to a half inch are possible in localized areas. The prime window for the roughest weather is late Wednesday night into the predawn hours of Thursday, June 18. Keep an eye on watches and warnings and be ready to move to shelter quickly if severe weather approaches, per NWS Pittsburgh.
What To Do
Before storms arrive, secure loose outdoor items and move any events or equipment indoors if you can. Make sure you have a reliable way to receive alerts, whether through a phone app, NOAA weather radio, or local emergency channels. If a severe thunderstorm or tornado warning is issued, head to a sturdy interior room away from windows, and avoid driving through flooded streets. We will update this forecast if watches or warnings are posted.
