Lake-effect snow is produced as cold winds blow clouds over warm waters. Some key elements are required to form lake-effect precipitation and which determine its characteristics: instability, fetch, wind shear, upstream moisture, upwind lakes, synoptic (large)-scale forcing, orography/topography, and snow or ice cover.
When lake-effect snow hits regions of the Great Lakes during late fall and winter, you start to hear meteorologists use terms like "feet of snow," "whiteout conditions," "blizzard" and "travel ...

Climate change will likely have a significant effect on the future of weather events on the snowbelt. On one hand, as temperatures increase in the area of the Great Lakes, making them free of ice for longer periods of time, snowfall could increase during lake-effect snow events and extend lake-effect snow season if the air is cold enough for snow.
How lake-effect snow forms. Lake-effect snow, which can last for only a few minutes to several days, develops from narrow bands of clouds that form when cold, dry arctic air passes over a large ...
What is lake effect snow. Lake effect snow occurs when cold air moves across the open waters of the Great Lakes creating snowfall, said Lily Chapman, a meteorologist at the NWS Forecast office in ...
Heavy snow is a fact of life near Great Lakes. Lake-effect snow goes hand-in-hand with living near a Great Lake. In many cases, a foot or two (30 to 61 centimeters) of snow will fall, but occasionally it can get out of hand. In November 2022, lake-effect storms dumped more than 6 feet (1.8 meters) of snow in western New York. Those wintry ...
A lake effect snow warning is a bulletin issued by the National Weather Service in the United States to warn of heavy snowfall accumulations that are imminent from convective snow generated by very cold airmass passing over unfrozen lakes (lake effect snow). The criteria for amounts may vary significantly over different county warning areas. [1]
