Early risers woke up to a chilly, gray start across Pittsburgh on Thursday. As of 5:35 a.m. Thursday, April 30, 2026, the Allegheny County observation at KAGC was reporting cloudy skies and about 48°F across the metro. Forecasters expect highs to stay below seasonal norms today, topping out in the mid-50s with a chance for a few spotty morning showers during the commute.
Overnight Frost Advisory
A Frost Advisory is posted from 12:00 a.m. Friday, May 1, to 9:00 a.m. Friday, May 1, for parts of the region. Higher terrain and areas north of I-80 have the best shot at dipping to near-freezing temperatures. Eastern Tucker County and some northern ridges may briefly slip into freeze territory, and forecasters say additional frost or freeze alerts could be needed later in the weekend. Sunday looks drier, but a series of disturbances is on track to bring daily rain chances and an elevated thunderstorm risk early next week, according to the National Weather Service.
Thursday Commute And Weekend Outlook
For Thursday, expect a slight chance of rain showers before 11:00 a.m., with northwest winds around 6 to 12 mph and a high near 56°F. Skies should brighten a bit during the afternoon as clouds thin out. Friday turns cooler and wetter, with rain showers likely after about 8:00 a.m., so plan on wet roads and a slower-than-usual morning drive. Saturday should moderate into the mid-50s with scattered showers possible, while Sunday is shaping up as the pick of the weekend with mostly sunny skies and highs near 60°F.
Protect Plants And Pets
Gardeners and pet owners will want to take the chill seriously. Cover or bring in tender plants Friday night and again Saturday night if skies clear out; low-lying yards, exposed porches, and garden beds are most vulnerable to frost damage. This chilly flip follows a short warm stretch earlier in the week, a turnaround covered in the brief spring "sweet spot", and it is worth checking zone-specific guidance if you manage a garden or small farm. For zone maps or the latest advisories, stick with local forecasts or the NWS office.
Bottom Line
Short-lived frost is possible overnight into Friday in the colder pockets, so protect sensitive plants and be ready for a wetter stretch that moves in Friday and lingers in spots into next week. Keep an eye on forecasts through Sunday for any updated frost alerts and for fine-tuning the timing of next week’s showers and thunderstorms.
