Pennsylvania — Breath turns visible instantly this morning as biting air settles over the Ohio River valleys. Streetlights glow against dry pavement, but the cold feels unforgiving. Temperatures hover near single digits, with wind chills well below zero across much of the Pittsburgh metro.
This Winter Weather Alert centers on extreme cold now, followed by several rounds of snow chances. Early today stays mostly quiet, though flurries may drift in by late afternoon. Highs struggle to reach the upper 20s, and wind chills hover near zero during the morning commute.
Cold air remains locked in tonight. Temperatures fall into the lower 20s, setting the stage for snow development on Tuesday. Light snow becomes more likely by afternoon, with chances increasing through Tuesday evening. Accumulations look light for now, but visibility may briefly drop during heavier bursts.
By Wednesday, skies partially clear, yet the cold tightens again. Morning lows dip into the single digits, with highs only in the mid-20s. Roads may refreeze quickly after any daytime melting. Flash freezing remains a concern, especially on bridges and ramps along I-376, I-279, and Route 28.
Another system approaches late Thursday into Friday. Snow chances rise again, and this round could be more impactful. Latest models show widespread snow Friday, with travel impacts likely across Allegheny County. Meteorologists are closely tracking this setup as it pushes toward the Feb 6–8 weekend.
Despite the deep freeze, longer-range signals hint at moderation late next week. For now, plan extra travel time, dress in layers, and keep vehicles winter-ready. Conditions may change quickly after sunset each evening.
