Pittsburgh woke up under a thick, patchy blanket of fog on Sunday morning, June 28, with visibility in some spots dropping to a quarter mile or less and early drivers tapping the brakes on the commute. It felt every bit as sticky as it looked, with temperatures stuck in the upper 60s and low clouds hanging over the river valley well into midmorning.
Fog To Clear Before Afternoon Storms
The fog is expected to thin by late morning, trading low clouds for a more active sky. Scattered showers and a few thunderstorms are possible between noon and 5 p.m., with showers and storms becoming more likely later in the afternoon and a high near 85°F still on tap. East winds should stay light, generally 0–5 mph, but any thunderstorm could briefly dump heavy rain and knock visibility down in a hurry. A Special Weather Statement in effect through 10 a.m. warned that some locations could see visibility fall below a quarter mile, and the National Weather Service in Pittsburgh keeps the chance of precipitation near 60% for today.
Evening And Overnight
Early this evening could bring a few more showers and thunderstorms, then skies should turn partly cloudy overnight with patchy fog forming again and a low near 67°F. Light east winds will keep the air feeling muggy and may help fog redevelop before Monday morning, so late-night and early-commute drivers should be ready for pockets of reduced visibility.
Scorching Stretch Next Week
Monday offers only a modest breather, with highs still expected to reach around 90°F, before the region flips into a hotter pattern from Tuesday through Thursday. Highs could climb into the mid to upper 90s, and overnight lows will stay on the warm side. Forecasters have flagged a multi-day heat risk next week, and our earlier coverage in this stormy lead-up to this heat wave breaks down expected highs and heat-safety guidance.
How To Prepare
For now, drivers should build in extra time for the foggy morning commute, flip on low-beam headlights, and avoid stopping on the roadway unless they can pull completely off the pavement. Once the heat settles in by midweek, check on older neighbors or anyone without reliable air conditioning, drink plenty of water, and call 2-1-1 or use county resources to find open cooling centers if your home is too hot.
