Lake-effect snow blankets New York again; explore our detailed snowfall maps
New York is experiencing significant lake-effect snow, particularly in the western and central regions. Such weather phenomena are expected to persist due to warmer lake temperatures and reduced ice cover on Lake Ontario this winter. This trend may lead to ongoing lake-effect snowfall, affecting travel conditions.
Current Snowfall Conditions
As of November 17, heavy snowfall is creating hazardous travel conditions across much of the state. The National Weather Service (NWS) reports that some areas could accumulate an additional 2 to 5 inches of snow by Tuesday morning. The snowfall bands are primarily influenced by Lake Huron, currently displaying at least three distinct bands.
Forecast and Patterns
The snow bands are expected to shift through the day. Initially, they will move southwest into northwest Pennsylvania and southeastern Chautauqua County before returning northeast across Chautauqua and Cattaraugus counties later in the afternoon. Conditions will evolve into light snow showers and flurries tonight.
- Current Snow Accumulation:
- Western New York: 1 to 3 inches expected through Monday.
- Eastern Wayne County to northern Cayuga County: potential for 2 to 5 inches.
Upcoming Weather Changes
By midweek, high pressure is anticipated to dominate the region’s weather atmosphere, effectively halting the lake-effect snowfall. This change will also introduce more seasonable temperatures across New York. The NWS has indicated that while snow accumulations may be limited, travel could still be dangerous in certain areas.
Impacts on Travel and Preparedness
Residents and travelers are advised to stay informed about local weather conditions. The lake-effect snow may lead to slippery roads, particularly near the lakeshore and along routes such as the New York State Thruway, where surface temperatures are slightly warmer and may reduce total snow accumulation.
As the weather continues to develop, individuals should monitor updates for snowfall predictions and travel advisories. With winter approaching, awareness of shifting conditions is key to maintaining safe travel throughout New York.
