PITTSBURGH, Pa. – Patchy fog could slow Tuesday morning traffic across Pittsburgh, especially along Parkway East and I-376, where visibility may drop quickly. Commuters should plan extra time for travel and use low-beam headlights during the early rush hours.
According to the National Weather Service in Moon Township, fog will form after midnight and persist into Tuesday morning before giving way to sunshine. East winds around 5 mph will remain light, keeping temperatures mild with a high near 83 degrees. Conditions clear quickly by late morning, offering bright skies for most of the afternoon.
Drivers should remain cautious during the morning commute, as fog pockets can develop suddenly near rivers and low-lying areas. Schools and early bus routes may also be affected by slower travel times. Residents should also check on morning flights at Pittsburgh International, where patchy fog may cause brief delays.
The midweek pattern stays warm, with highs near 90 degrees through Thursday. Air conditioners will keep working hard before relief arrives late in the week. By Friday, highs dip into the lower 80s, and the first hint of fall-like air settles in by the weekend.
Expect cooler mornings by Saturday, with overnight lows in the lower 60s. Sunshine dominates most of the period, creating ideal weather for outdoor plans once Tuesday morning fog lifts.
Stay alert for updated advisories from the National Weather Service if fog thickens more than expected. Another round of patchy fog is possible Wednesday night into Thursday morning.
