PITTSBURGH, Pa. – A calm, cool morning greets Allegheny County with starlit skies and a brisk west breeze sweeping across the rivers. By sunrise, clouds will gradually thicken, signaling a quiet start to a changeable week for western Pennsylvania. Leaves swirl across damp sidewalks as fall’s familiar chill lingers — comfortable for now, but a reminder of the cooler push on the horizon.
According to the National Weather Service in Pittsburgh, the region will stay mostly dry through Tuesday, offering one of the most pleasant days of the week. Sunshine returns with highs near 58°F, and west winds up to 15 mph make for crisp, clear conditions. Wednesday brings the next shift: a cold front sliding through the Ohio Valley, pulling clouds and scattered rain into southwestern Pennsylvania by late afternoon. Gusts near 25 mph could make travel along I-79 and the Parkway West tricky during the evening commute.
By Thursday, skies clear again briefly with highs in the mid-50s before another round of rain likely arrives Friday. That system may bring a sharper drop in temperature heading into the weekend, with some areas dipping near freezing north of Pittsburgh. While no snow is expected yet, models hint that colder air from the Great Lakes could set the stage for a potential early-season mix later this month — possibly around Thanksgiving week.
For now, residents should enjoy Tuesday’s sunshine and prepare for slippery roads and slower travel by midweek as November’s weather rhythm turns more unsettled.
