As the cold air flows over the warm water, the relatively warm lake water heats the air's bottom layer as lake moisture evaporates into the cold air.
As this happens, friction with the ground, which is greater than the friction between the lake's water and the moving air, slows the winds.
This is why the heaviest lake effect snow falls on hills inland from the great lakes.

  Lake effect snow - Wikipedia, the free encyclopedia
Lake effect snow, also called a snowsquall, is produced in the winter when cold winds move across long expanses of warmer lake water, picking up water vapor which freezes and is deposited on the lee shores.
Lake effect snows at the Tug Hill Plateau on the southeastern side of Lake Ontario frequently set the daily records for snowfall in the United States.
Lake Erie also produces a similar effect for a zone stretching from the eastern suburbs of Cleveland to Buffalo, but Lake Erie often freezes due to its shallowness, and ice cover stops the lake effect.

 Lake Wobegon effect - Wikipedia, the free encyclopedia
The Lake Wobegon effect, also called the Lake Wobegon fallacy and the better-than-average effect, is a term used by psychologists to refer to the human tendency to report flattering beliefs about oneself and believe that one is above average.
The effect is similar and may be related to ingroup bias and wishful thinking.
In contrast, the worse-than-average effect refers to a tendency to underestimate oneself in certain conditions, which may include self-handicapping behavior.

 Lake Effect Snow - Part 2
Lake-generated snow squalls form when cold air, passing for long distances over the relatively warm waters of a large lake, picks up moisture and heat and is then forced to drop the moisture in the form of snow upon reaching the downwind shore.
Lake-effect snows are common over the Great Lakes region because these large bodies of water can hold their summer heat well into the winter, rarely freeze over and provide the long fetch which allows the air to gain the heat and moisture required to fuel the snow squalls.
As a result, winter weather in the lee of the Great Lakes shows a complex variability of snowfalls, with areas of deep snowfall are often adjacent to areas with relatively little snow.

 Lake Effect Snow   (Site not responding. Last check: 2007-10-04)
Climatic "lake effects" stem from the water surface that the lakes expose to the atmosphere and from the contrasting physical properties of land and water.
Lake effect snowfall can account for 30% to 60% of the total snowfall at some locations immediately to the lee of the lakes.
The major lake effect snowbelts are clearly shown by the darker shaded areas.

 Lake Wobegon - Wikipedia, the free encyclopedia
Lake Wobegon is a fictitious town in Minnesota, claimed to have been the boyhood home of Garrison Keillor, who reports the News from Lake Wobegon on the radio show A Prairie Home Companion, broadcast live every Saturday afternoon over Minnesota Public Radio and public radio stations throughout the US.
Lake Wobegon is the seat of Mist County, a tiny county near the geographic center of Minnesota that supposedly does not appear on maps because of the incompetence of surveyors who mapped out the state in the 19th century.
Our Lady of Perpetual Responsibility parish and the Lake Wobegon Lutheran Church are there, although Keillor identifies the founders of Lake Wobegon as New England Unitarian missionaries who came to convert the Native Americans through interpretive dance.

 LAKE-EFFECT SNOW FORECASTING
The temperature difference between the lake and the 850 millibar level is usually greater than 13° C for significant lake-effect snow to occur.
The lake must be of large size (fetch greater than 100 kilometers) and exist at a latitude where cold temperatures are experienced.
If the lake is of a large size, latent heat release due to condensation and warming by conduction and turbulent mixing will create a large relatively warm air mass at the surface.

 NOAA Home Page - Question of the Month
Lake effect snows yielding as much as 193 cm (76 inches) of light-density snow in 24 hours and fall rates as high as 15 cm (6 inches) per hour have been reported.
In general, lake effect snowfall contributes between 30 and 60 percent of the annual winter snowfall on the eastern and southern shores of the Great Lakes.
The distribution of lake effect snow is dependent upon several factors—many are associated with the prevailing meteorological situation, while others are a function of the physical geography of the land and water in the immediate area:

 Impacts of Climate Change in the Great Lakes
Despite this significant increase in precipitation, lake water levels are expected to fall by 1.5 to 8 feet by 2100 because of the higher temperatures, with serious implications for ecosystems and the economy.
Aquatic ecosystems of the Great Lakes region support delicate, deeply interconnected webs of life which are highly adapted to the physical (and biochemical) characteristics and cycles of the lakes themselves.
If primary production in lakes declines as projected, stocking strategies may be required to rebuild stocks of native species that have survived in the lakes through centuries of post-glacial change.

 Lake Effect Snow - Part 1
In areas south of one of the Great Lakes, cold front passage will often be followed by a 24 to 36-hour period of blustery northerly or westerly winds, falling temperatures and persistent flurries of fluffy snow.
Not so around the Great Lakes, where it is said: "During the winter, the weather clears up stormy." The cold air picks up substantial moisture as it moves over the Lakes and deposits it as snow inland from the downwind shore.
And, although the east and south shores of the Great Lakes are most likely to have lake-effect snowfalls, north and west shorelines can be hit if the air traversing the lake is cold enough and the distance the air passes over open water (known as the fetch) is large enough.

 The Great Lakes Atlas: Chapter Two
The weather in the Great Lakes basin is affected by three factors: air masses from other regions, the location of the basin within a large continental landmass, and the moderating influence of the lakes themselves.
Warmer climates mean increased evaporation from the lake surfaces and evapotranspiration from the land surface of the basin.
During the spring warming period, the rapidly warming nearshore waters are inhibited from moving to the open lake by a thermal bar, a sharp temperature gradient that prevents mixing until the sun warms the open lake surface waters or until the waters are mixed by storms.

 Geology of Lake Erie, Avon, Ohio
Though the Lakes have abbreviated histories, the formation of the basins is extremely complex and is based on the interpretation of past events through the analysis of the geologic record.
A cross section of Lake Superior is shown in the figure below to illustrate Precambrian crystalline rocks at the margins of the basin overlying relatively hard but highly fractured and riddled sedimentary rocks (which have undergone a slight degree of metamorphism) in the depression of the lake.
Lake Michigan lies wholly within the Paleozoic rock province of the region as does all of Lake Huron except for the north-northeastern shore which is on the edge of the Canadian Shield.

As it turns out, the difference between lake temperature and air temperature is one of the most important ingredients in making lake effect snow.
As previously mentioned, forecasters compare the atmospheric temperature at 850 mb to the lake temperature to gauge lake-effect snow potential, given that the lake is not frozen.
When the lake temperature is 13°C warmer than the atmosphere at 850 mb, and the atmosphere is cold enough to produce snow, it is possible for lake-effect snow to form.

 Lake Effect Snow   (Site not responding. Last check: 2007-10-04)
This is attributed to Lake Ontario because of its geographic proximity.
Lake effect snow occurs often during the winter months.
Due to the heat and moisture that the lake puts into the overlying air, the air close to the surface is very buoyant.

 Lake-effect snow
The lake surface evaporates, which is very effective when the wind is strong and the air dry (Dalton's equation, Note 4.E).
Certainly this effect is important in the case of Lake Baikal in Siberia.
Sometimes the lake-effect snow is concentrated along a narrow band due to mesoscale flows around the lake, in particular a landbreeze from one or opposing shores, e.g.

 Lake/Ocean Effect Snow: Basic Ingredients
One of the basic contributors to lake/ocean effect snow is the unstable lapse rate generated by the relatively warm water surface underlying the cold atmosphere during the cool season.
All of these warm water sources for lake/ocean effect snow also share the characteristic that they are situated in areas over which cold polar or arctic air masses frequently migrate in the cool season, which makes them climatologically favorable for the occurrence of lake/ocean effect snow.
The lake/ocean effect process can occur any time that the overlying air mass is sufficiently colder than the water surface, but the occurrence of snow typically commences in November for the lower Great Lakes, and earlier at higher latitudes.

 11 January 1999 -- Lake Effect Snow Bands in Western New York
Lake Effect Snow (LES) bands formed over Lake Erie and Lake Ontario on 11 Januray 1999, and affected parts of western New York state with snowfall rates of 1 to 3 inches per hour.
The synoptic-scale southwesterly flow was oriented along the axis of Lakes Erie and Ontario, allowing a long fetch of cold air (air temperatures near 10 F / -12 C) over the warmer water (non-frozen, water temperatures 32 to 43 F / 0 to +6 C).
One factor that is important in forecasting the occurrence and severity of LES is the difference in temperature between the relatively warm lake water and the cold air within the lowest 1-2 km of the troposphere.

 Veterans Day Lake Effect Snowstorm: November 9-14, 1996 in the Great Lakes
Lake Erie's surface water temperatures may still be near 60 F, while inland surface temperatures fall well below freezing during cold air outbreaks.
The strong temperature contrast between the lake and the polar or arctic air masses promotes turbulence and rising motions in the lower part of the air column which in turn produce clouds and precipitation.
The squalls may persist for hours in favored locations to the lee of the lakes, resulting in the famous lake effect snowstorms we hear so much about.

 The Lake Effect
Later, Sir Norman Watson, onetime owner of the ski hill and the eccentric son of an English margarine baron, spent years trying to transform Lake Louise into the "Engadin of the New World"—complete with brown cows, a string of backcountry huts for the well-heeled skier, and imported Swiss peasants.
It was just… pristine." Lake Louise may not be a hotbed of transcendental insight, but I let his half-baked rumination slide.
My remaining days at Lake Louise were a similar mix of high and low tastes—filet mignon of bison dipped in boiling fondue oil at the Chateau's wood-paneled Walliser Stube, followed by shepherd's pie at the locals' bargain hangout, the Outpost Pub, and a bunk at the Alpine Centre Hostel (all rumors—yoga, salmon—were true).
