A lake-effect snow warning is issued when NWS is at least 80% confident that part of the county will see six inches or more of snow in12 hours or less.

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, relatively mild lake.

Lake-effect snow is typically localized and intense, affecting areas immediately downwind of the lake. Example: Lake-effect snow buried parts of eastern Cuyahoga County with 6 inches of 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 Marquette.

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.

Lake effect snow, on the other hand, is a localized phenomenon caused by cold air moving over a warmer body of water, picking up moisture and depositing it as snow when the air cools over land.

The heavy lake effect snow prompted the Buffalo Bills to ask fans for help clearing snow out of Highmark Stadium ahead of the team's game against the San Francisco 49ers on Sunday night.
