PITTSBURGH, Pa. – Streetlights flickered over quiet, misty valleys early Monday as fall’s crisp calm settled across western Pennsylvania. The dry air and clear skies may start the week serenely, but clouds and rain loom just beyond the horizon.
According to the National Weather Service in Pittsburgh, Monday and Tuesday will stay sunny and seasonable with highs near 60. Morning lows dip into the upper 30s, leaving a light chill for early commuters and bus stops. East winds will increase slightly Tuesday afternoon, signaling the approach of a wetter stretch midweek.
By Wednesday, a developing system over the Ohio Valley will bring rain chances rising to 80%, with showers likely after midday. East winds up to 14 mph could gust higher during heavier bands of rain, especially along the I-79 and I-376 corridors. Expect slick roads and slower travel through the afternoon and evening as rainfall totals climb toward a half inch.
The damp pattern continues into Thursday and Friday, keeping skies mostly gray and temperatures cooler. Daytime highs hover near the lower 50s with lows around 42. The good news — Halloween weekend should gradually dry out. Skies are expected to clear by Friday evening, offering a crisp, calm backdrop for trick-or-treaters with temperatures in the upper 40s.
After all, it’s late October — and models hint at a chillier November start, possibly bringing the first flurries to the higher ridges of southwestern Pennsylvania before long.
