Lake Effect Snow Warning Issued for New York: Monday to Wednesday

 

The National Weather Service has issued a lake effect snow warning for Wyoming, Cattaraugus, and Erie counties, effective from 1 a.m. Monday until 10 a.m. Wednesday.

According to the advisory, "Heavy lake effect snow is expected, with total accumulations ranging from 10 to 20 inches in the most persistent snow bands, primarily affecting northern Cattaraugus, southern Erie, and western Wyoming counties." The most intense and impactful snowfall is anticipated between Monday and Tuesday evening.

The weather service cautions that "travel will be very difficult, with poor visibility and deep snow covering roads." It also notes that "lake effect snow can create highly variable conditions, with heavy snow and reduced visibility in some areas, while nearby locations remain dry. Be prepared for sudden changes in weather, visibility, and road conditions."

About Lake Effect Snow Warning

When cold air moves over the unfrozen, relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lower atmosphere. This causes the air to rise, leading to cloud formation and the development of narrow bands that can produce snowfall at rates of 2 to 3 inches per hour or more.

Wind direction plays a crucial role in determining which areas will experience lake effect snow. Heavy snow can be falling in one location, while just a mile or two away, the sun might be shining. The physical geography of the land and water also significantly influences this phenomenon. Meteorologists at the National Weather Service take these and other factors into account when forecasting lake effect snow.
