PITTSBURGH, PA – The steel-gray skies of early December hang still over western Pennsylvania this Friday morning as a deep chill grips the region. At 15°F, the air feels like winter has truly arrived — the kind that stings fingers and clings to the breath. That cold sets the stage for light snow and a wintry mix expected this weekend, adding the first taste of seasonal slickness to area roads.
According to the National Weather Service in Pittsburgh, clouds will increase through the day with temperatures struggling into the mid-30s. By late Saturday, a quick-moving disturbance slides in from the Ohio Valley, bringing a slight chance of snow early, changing to a rain-snow mix by Sunday. While totals should remain light — under two inches in most areas — the timing could impact drivers through the I-79, I-376, and Parkway West corridors, particularly early Sunday when surfaces may briefly glaze before temperatures rise above freezing.
Winds will stay calm, but melting and refreezing are concerns as nighttime lows dip back into the 20s. Drivers are urged to use caution on bridges and overpasses, where flash-freeze slick spots often appear first.
Sunday remains cloudy and cold, with highs near 37°F, followed by another reinforcing shot of Arctic air by Monday. Long-range models now hint at a stronger storm window between December 11–17, potentially bringing heavier snow across the Great Lakes and upper Ohio Valley — something early holiday travelers should monitor closely.
Keep coats, ice scrapers, and de-icer handy through the weekend.
