Pennsylvania – Thick fog is hanging low over Pittsburgh right now, softening headlights and cutting visibility to under two miles in some spots. Roads feel damp, and the air sits heavy as conditions shift through the day.
According to the National Weather Service, patchy fog continues through the morning with scattered showers developing and thunderstorms possible by mid to late afternoon. Temperatures will climb quickly, reaching near 82°F, fueling instability across western Pennsylvania.
Across Allegheny County, drivers are already seeing reduced visibility along I-376, I-79, and Route 28. Expect sudden slowdowns where fog thickens, especially near river valleys. Keep headlights on and allow extra distance between vehicles.
By mid-afternoon, showers and thunderstorms begin to develop. Some storms could bring brief heavy rain, gusty winds, and lightning, creating quick travel disruptions during the evening commute. Conditions may deteriorate quickly after sunset as storms become more widespread.
Friday continues the active pattern. Scattered showers early may give way to more storms later in the day, with highs near 80°F. Expect another round of wet roads and potential delays.
The weekend starts warm but turns unsettled. Saturday reaches the low 80s before rain becomes likely by night, with a 100% chance of showers creating widespread wet conditions. By Sunday, cooler air settles in, dropping highs into the mid-50s under mostly cloudy skies.
Early next week brings calmer, cooler weather with gradual clearing.
