Lake-Effect Snow in Southern Erie, Pennsylvania

A trough of surface low pressure was draped west to east across the southern Great Lakes January 14th and 15th, with cold west-northwest winds wrapping around this trough and over Lake Erie. This set the stage for a period of moderate to heavy lake effect snow into Erie County. The heaviest accumulations occurred during the afternoon and evening hours of the 14th, when a west to east oriented band of snow pushed off of Lake Erie with snow rates briefly in excess of one inch per hour. These snow rates led to reduced visibility and snow-covered roads, hampering travel. Snow continued through January 15th, though gradually lessened in intensity. Select trained spotter snowfall reports include 15 inches in Greene Township, 14.3 inches in Greenfield Township, 14 inches in Millcreek and Union City, 12 inches in Edinboro and 10.7 inches in Cherry Hill. 10.2 inches was measured in Corry by a CoCoRaHS observer.
