Lake-Effect Snow — Southern Erie, Pennsylvania

2022-11-16 to 2022-11-17 · Southern Erie, Pennsylvania

Event narrative

Cold air spilled into the region and across Lake Erie on November 16th, allowing lake effect snow to develop in a west to east band into Erie County. This band was initially light and mixed with rain at times, limiting accumulations through most of the afternoon. More appreciable accumulations began occurring during the late afternoon and early evening in Erie County as the band intensified and changed to all snow. Snow rates became heavy by late evening across northern Erie County, with the band pushing inland into southern Erie County around midnight. Snow continued overnight before tapering significantly around sunrise November 17th. One more organized band of snow developed and lifted northeast across Erie County during the afternoon hours, before exiting to the northeast by early evening. Snow rates of 1 to 2 inches per hour occurred in the heart of the intense lake effect snow overnight and into the early morning of November 17th, with rates briefly exceeding 1' per hour again as snow re-organized during the afternoon hours of the 17th. This heavy snow resulted in low visibility and snowy travel conditions on area roadways. Luckily, the heaviest snow occurred overnight, though I-90 was closed near Springfield Township due to multiple vehicle accidents along the roadway during the morning hours of the 17th. No injuries were reported. The highest recorded snowfall of the event was 16' measured by a trained spotter in Greenfield Township. Other selection snowfall totals include: Trained spotters measuring 15.2' in Colt Station, 13.1' in Cherry Hill, and 11' in Edinboro. CoCoRAHS observers measured 11.3' in Millcreek Township and 9.8' in Corry, with a cooperative observer reporting 8.9' in Union City.
