Johnstown, PA – A widespread Winter Weather Advisory remains in place across western and northern Pennsylvania, where persistent snow showers and strong winds are making travel difficult through early Friday morning.
Forecasters at the National Weather Service in State College say the region will continue to see bursts of snow and rapidly changing conditions, with Cambria and Somerset Counties under an advisory until 10 a.m. Thursday, and Cameron, Elk, Potter, and Clearfield Counties remaining in advisory status until 4 a.m. Friday.
Ongoing Snowfall and Strong Gusts Across the Region
Snow showers are expected to continue through the overnight hours, with forecasters noting that 1 to 3 additional inches of accumulation are likely. Isolated pockets in the northern tier may see up to 5 inches where lake-effect bands set up and remain steady.
Wind gusts reaching 45 mph will contribute to blowing snow, drifting, and poor visibility. These conditions will be most noticeable along open stretches of roadway and higher elevation zones, where squalls can quickly reduce visibility to near zero.
Travel Impacts for Morning and Evening Commuters
Officials warn that the mix of fresh snow, slick roads, and strong winds will cause challenges during both the morning and evening commute periods. Drivers may encounter sudden whiteout conditions, particularly as heavier squalls move across major travel corridors.
The National Weather Service advises motorists to slow down, leave extra space between vehicles, and prepare for delays. Road conditions can change rapidly, even over short distances.
What the National Weather Service Is Saying
Forecasters stressed the unpredictability of squalls and the potential for brief but dangerous conditions.
“Snow showers will persist through Thursday morning with gusty winds leading to reduced visibility and hazardous travel,” the agency noted in its latest advisory.
Residents are encouraged to monitor official updates and to use 511PA for real-time travel conditions before heading out.
Regions Facing the Strongest Weather Impacts
The most severe impacts are expected in counties already under the extended advisory. Northern counties including Cameron, Elk, Potter, and Clearfield may continue experiencing lake-effect snow bands well into early Friday, allowing accumulations to build.
Meanwhile, parts of western Pennsylvania—particularly Cambria and Somerset Counties—will see persistent gusts that enhance blowing and drifting through Thursday morning.
Conditions Expected to Improve Late Thursday Night
Forecasters expect gradual improvement late Thursday night as winds begin to ease and snow bands weaken. Temperatures will remain below freezing, meaning untreated roads could stay slick into early Friday.
Residents should continue to use caution when driving, walking, or clearing snow, especially during periods of stronger gusts.
Staying Prepared for Rapid Weather Changes
Winter weather advisories serve as a reminder that travel can become dangerous with little warning. Officials recommend keeping emergency kits in vehicles, checking local forecasts frequently, and allowing ample time to reach destinations safely.
If conditions deteriorate quickly, the safest option may be to delay travel until roads improve.
