FINAL Call Snow & Ice Accumulation Forecast for Thursday – Friday Significant Winter Storm
Another winter storm in Pennsylvania that will bring very different impacts depending on where in the state you are. Significant snowfall and major ice accumulation likely in some areas, while others see mostly rain. Let’s get right into what you can expect.
Weather Alerts
Timing
Precipitation will move early Thursday morning in Southwest PA to late Thursday morning in Northeast PA. We expect the Alleghenies Mountains to start as freezing rain, while all areas east will begin with sleet. There’s a chance areas east of the Susquehanna River may start as snow. As precipitation becomes heavier, locations generally east of I-99 and north of I-76 are expected to switch to heavy snow.
Heavy snow will then continue in those areas, but rain/snow line will begin working north Thursday afternoon and evening. There may also be a brief period of sleet again before changing to rain. This changeover will come very early on in the storm in Southeast PA, and much later farther north. Below is the latest High Resolution NAM model simulation for most of the storm’s duration.
Road Impacts & Power Outages
Due to the storm beginning in the morning, road impacts will be high. Thursday morning’s commute will vary by location, but the evening will be treacherous nearly everywhere besides southwest and southeast PA. The Friday morning commute should be OK besides in the mountains of Northeast PA.
Widespread power outages are possible in Allegheny Mountains and likely in the Laurel Highlands Thursday afternoon through Friday morning. Scattered power outages are possible just outside of those areas as well, view ice map for reference.
