Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water. The lower layer of air, heated by the lake water, picks up water vapor from the lake and rises through colder air. The vapor then freezes and is deposited on the leeward (downwind) shores.
Lake-effect snow (also ocean-effect snow) – Occurs when relatively cold air flows over warm lake (or ocean) water to cause localized, convective snow bands. [6] [7] Mountain snow – Orographic lift causes moist air to rise upslope on mountains to where freezing temperatures cause orographic snow.
Lake effect snow warning. 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 ...
The lake-effect snow will closely follow a winter storm that will moved off the mid-Atlantic coast after dropping several inches of snow into Friday evening. Lake-effect snow is generated from ...
There have been a few close calls with outbreaks of lake-effect snow so far this season, but it appears the one poised to unfold Sunday and into the new week is unavoidable. And, AccuWeather ...
As of early Tuesday, lake-effect snow during the outbreak has piled up to between 3 and 4 feet in the towns south of Buffalo, New York. In the city of Buffalo alone, snowfall through midday Monday ...
The Great Salt Lake effect is a small but detectable influence on the local climate and weather around the Great Salt Lake in Utah, United States. In particular, snowstorms are a common occurrence over the region and have major socio-economic impacts due to their significant precipitation amounts. The Great Salt Lake almost never freezes and ...
The lake-effect will tend to align in a more northwest-to-southeast fashion with the weekend Arctic air outbreak, bringing heavier snow into other snow belts farther to the east, such as ...
