Pennsylvania Faces Growing Winter Storm Threat on December 26 as Snow and Ice Risks Increase Across the State
PENNSYLVANIA — Forecast data continues to signal a developing winter storm threat for Friday, December 26, with snow and ice becoming increasingly likely across large portions of the state, according to probability maps and model guidance released this week. While the exact storm track remains uncertain, confidence is growing that hazardous winter weather will impact Pennsylvania during the Friday-to-Saturday timeframe.
Snow and Ice Threat Increasing Statewide
Probability maps indicate a clear north-to-south gradient in precipitation type, with snow favored across northern and northeastern Pennsylvania, while freezing rain and ice become more likely across the southwest and central portions of the state.
Snow probabilities climb sharply across northeast Pennsylvania, where several locations show 70–90% chances of snowfall during the 7 a.m. Friday to 7 a.m. Saturday window. These probabilities suggest a strong likelihood of accumulating snow if current trends hold.
Meanwhile, ice probabilities exceed 45–55% across southwest and central Pennsylvania, highlighting an elevated risk for freezing rain and slick road conditions, especially during periods of overnight or early morning precipitation.
Heavier Snow Favored in Northeast Pennsylvania
Ensemble snowfall guidance supports higher snow totals across northeast Pennsylvania, where colder air is more firmly established. While exact accumulation amounts remain uncertain at this range, model signals suggest moderate snowfall is possible, especially in areas where precipitation remains predominantly snow.
Cities and towns in this region may experience snow-covered roads, reduced visibility, and travel disruptions, particularly if precipitation rates increase during peak travel hours.
Ice Risk Raises Travel Concerns in Southwest Pennsylvania
Southwest Pennsylvania faces a different set of challenges, with freezing rain emerging as the primary concern. Ice probabilities near or above 50% indicate a meaningful risk for glazed roadways, icy bridges, and hazardous driving conditions.
Even light ice accumulation can lead to rapidly deteriorating travel conditions, and forecast data suggests this region should be monitored closely as temperature profiles remain marginal.
Forecast Still Evolving, Impacts Could Shift
Meteorologists caution that storm details remain subject to change, including precipitation type boundaries and intensity. Small shifts in temperature or storm track could significantly alter local impacts, especially in transition zones between snow and ice.
However, the overall signal for impactful winter weather across Pennsylvania is strengthening, making this a system worth close monitoring through the remainder of the week.
What Pennsylvanians Should Watch For
Residents should prepare for:
- Snow-covered roads in the northeast
- Icy conditions and freezing rain in the southwest
- Possible travel disruptions Friday into early Saturday
- Rapid forecast updates as models refine storm details
Staying informed and planning ahead will be essential as this potential winter storm approaches.
Winter weather can change quickly, and this developing system is a reminder that late December remains an active period for impactful storms.
