Lake-Effect Snow in Northern Cayuga, New York
Lake-Effect Snow December 1, 2019 – December 2, 2019 · Northern Cayuga, New York
The wider storm
An upper level low traversing the country brought freezing rain and snow across our region. While precipitation started as freezing rain over western New York, it quickly shifted to rain. Easterly flow locked colder air east and southeast of Lake Ontario where predominately snow fell. A tightening baroclinic boundary, with frontogenetic forcing, paved the way to heavy snow accumulation there. This event occurred on the busy travel Sunday after the Thanksgiving holiday, meaning impacts to transportation were of keen interest. Storm total accumulations of heavy, wet, ice-rimed snow included 8.8 inches in Minetto, 7.4 inches in Fulton, 7 inches in Osceola, 7.1 inches in Geneva, and 7 inches at East Bay Park.
