Pennsylvania – Headlights glow through thick fog this morning as mist hangs low over Pittsburgh, cutting visibility and slowing traffic right now. Wet pavement reflects brake lights along I-376 and I-279, where drivers are already easing speeds. Temperatures hover near 51°F, but the real hazard is visibility dropping to around two miles in spots.
According to the National Weather Service in Pittsburgh, patchy fog and scattered showers continue through late morning before gradually improving by midday. Northwest winds between 10 and 16 mph, with gusts up to 26 mph, will help push moisture out later today. Rain remains light, but damp roads and low clouds will linger into early afternoon.
Across Allegheny County and surrounding areas, drivers should expect reduced visibility on bridges and in river valleys. Conditions can shift quickly between clear patches and dense fog. Use low beams and allow extra following distance, especially during stop-and-go traffic.
Skies begin to clear later today, and cooler air settles in tonight. Temperatures drop sharply to near 25°F, raising concern for refreezing on untreated surfaces. Any leftover moisture could turn into black ice early Tuesday, particularly on overpasses and shaded roads.
Sunshine returns Tuesday with highs near 51°F, offering a calmer stretch. By Wednesday, a spring warm-up pushes temperatures into the mid-60s with partly sunny skies. Clouds increase Thursday, with rain developing later in the day and becoming more widespread into the night.
This week delivers a classic March swing, from fog and damp roads to sunshine and then back to rain. Stay alert during early drives and watch for icy patches after dark. What are conditions like in your neighborhood right now?
