State College, PA – A strong lake effect snow event is expected to impact northwestern Pennsylvania beginning late Sunday morning, prompting the National Weather Service (NWS) to maintain a Lake Effect Snow Warning for Warren, McKean, and Elk Counties. The warning is in effect from 10 a.m. Sunday through 1 p.m. Monday, with hazardous and rapidly changing conditions expected throughout the duration of the storm.
According to the NWS, heavy snow bands will develop off Lake Erie and push into the region, bringing 5 to 8 inches of accumulation and wind gusts reaching 50 mph. These strong winds, combined with steady snowfall, may reduce visibility to below one-quarter mile at times, creating whiteout conditions across open areas and higher terrain.
Roads, bridges, and overpasses will likely become slick and difficult to navigate as snow falls and drifts. Blowing and drifting snow may make it challenging for plow crews to keep roads clear, especially during the heaviest bands, which can shift quickly and create dangerous surprises for drivers traveling only a few miles.
The NWS emphasizes that lake effect snow can vary dramatically across short distances, with heavy snow in one town and clear skies in another. Motorists should be prepared for sudden drops in visibility and rapidly changing pavement conditions.
Officials advise delaying travel if possible. Those who must be on the roads should carry a winter storm kit with tire chains, booster cables, blankets, water, and other emergency supplies in case they become stranded.
The warning is expected to expire early Monday afternoon as lake effect bands weaken, though lingering gusty winds and patchy blowing snow may continue to impact open areas.
