Fog and low clouds are cutting visibility across Pittsburgh on Tuesday morning, with temperatures sitting in the upper 30s and spotty mist hanging near the river valleys. Skies are expected to break to partly sunny by midday, and highs should climb into the mid-50s this afternoon, making it the warmest day of the week so far.
What To Expect Today
According to the National Weather Service, the Dense Fog Advisory that covered parts of the area earlier has expired, although pockets of patchy fog could hang on into the morning commute. Winds will stay light, generally out of the southwest around 5 mph. The main issues will be reduced visibility on neighborhood streets and the potential for localized delays at smaller airports.
Midweek Rain And Gusty Winds
Rain moves back into the region on Wednesday, with highs rising into the upper 50s to near 60°F and southwest winds increasing to 6 to 14 mph, with gusts that could reach around 25 mph. A second weather system late Thursday into Friday is expected to bring steadier rain and pockets of heavier downpours, with some locations possibly seeing about a quarter to a half inch of rainfall overnight into Friday.
Weekend Outlook
A colder air mass settles in late Saturday into Sunday. Any lingering precipitation may briefly flip to a rain and snow mix before temperatures drop further. Highs on Sunday look to be in the upper 30s, with lows dipping to around the mid-20s overnight. That changeover raises the chance for light snow or slick spots Sunday night into Monday, so it is a good idea to keep weekend plans flexible.
Commute Notes
Plan on giving yourself extra time as the remaining fog gradually lifts and be ready for wet roads when the midweek rain arrives. The earlier advisory was covered in yesterday’s update; for fog-driving tips and local impacts, see our previous story on the earlier fog advisory reported by Hoodline,
