Lake-Effect Snow — Southern Erie, Pennsylvania

2025-11-27 to 2025-11-28 · Southern Erie, Pennsylvania

Event narrative

Following a strong cold front that crossed on November 26th, much colder air flowed in and allowed significant lake-effect snow to develop. This snow was initially carried into western New York by southwest winds, but gradually shifted south and west into the snowbelt region of Northwest Pennsylvania as winds turned more west-northwest on Thanksgiving. Heavy lake effect snow then continued into Black Friday before tapering off. Snow rates exceeded one inch per hour at times within lake effect bands, especially late Thanksgiving Day and night. A peak accumulation of 13.9 inches was reported by a CoCoRaHS observer in Corry. A cooperative observer in Union City reported 9 inches of snow. Selected trained spotter reports include 13.5 inches in Algin Township, 11.7 inches in Mill Village, 10 inches in Waterford and 7.6 inches in Edinboro.
