LAKE EFFECT SNOW WARNING
A lake effect snow warning is a type of weather warning issued by the National Weather Service (NWS) in the United States when conditions are favorable for the production of significant amounts of snow in areas below the Great Lakes. This meteorological phenomenon occurs during the cold winter months when cold, dry winds blow over the relatively warm waters of the Great Lakes, causing intense snowmelt in localized areas. KeyPoint about lake effect snow warning: Formation: Lake effect snow is mainly caused by the temperature difference between the cold air masses moving over the Great Lakes and the relatively warm water. When cold air picks up moisture and heat from the lake surface, it becomes unstable and rises rapidly, forming clouds and causing snowfall. Areas Affected: Lake Effect Snow Warnings typically affect areas east and southeast of the Great Lakes, including New York, Pennsylvania, Ohio, Michigan, Indiana, and occasionally parts of Canada.
