Pittsburgh, Pennsylvania – Patchy, dense fog is blanketing parts of Allegheny County this morning, with visibility dropping sharply on routes like PA-885 and the Parkway East. By late morning, rising temperatures and sunshine will quickly take over, sending highs to a humid 88°F across Pittsburgh. Drivers should allow extra time for their morning commute and use headlights, as slick spots and sudden changes in visibility remain possible until 9 a.m.
According to the National Weather Service, the fog will dissipate before midday, ushering in a partly sunny, summer day with light and variable winds. Air quality could be reduced in valley areas during the fog, so residents with respiratory conditions should limit outdoor activity early. Stay alert for rapid temperature swings—after a cool, foggy start, the heat will build quickly, and hydration is key.
Wednesday’s heat is just the start of a steamy stretch. On Thursday, there’s a 50% chance of thunderstorms by late morning, with highs again near 88°F and gusty winds possible. Friday will see more sun but afternoon storms are likely, pushing the mercury to 89°F. Saturday ramps up with a hot 91°F and continued storm chances in the afternoon. Thunderstorms become more likely into Sunday, which could see another round of heavy rain and highs around 88°F.
Prepare for changing summer conditions—keep your water bottle handy, avoid strenuous work during peak heat, and check for real-time alerts on your mobile device.
