What is the Difference Between Lake Effect Snow Storms and Regular Winter Storms?
A recent weather reader asked the following question on lake effect snow - ...
The Veteran's Day storm of November 9-14, 1996 may be the most severe early season lake effect snow (LES) storm the Great Lakes has witnessed in the past fifty years.
Lake Effect Snow - permalink - collapse
All > Science > Weather
Snow showers that are created when cold, dry air passes over a large warmer lake, such as one of the Great Lakes, and picks up moisture and heat.
Lake Effect Snow Advisory
This product is issued by the National Weather Service when pure lake effect snow (this is where the snow is a direct result of lake effect snow and not because of a low pressure system) may pose a hazard or it is life ...
lake effect"Generally, the effect of any lake in modifying the weather about its shore and for some distance downwind. In the United States, this term is applied specifically to the region about the Great Lakes or the Great Salt Lake.
Lake Effect: The effect of any lake in modifying the weather and climate along its shore and a distance inland, which depends on the size of the lake.
Lake effect storm - small but intense snowstorm downwind of an open lake.
LAKE EFFECT SNOW- Snow produced from lifting of moisture from a large lake such as the Great Lakes.
Lake Effect Snowstorm
Snowstorm occurring on the shore of a lake or downwind from a lake, arising as a result of the modification of the air during its passage over the water.
Lake effect- The effect of a lake (usually a large one) in modifying the weather near the shore and down wind. It is often refers to the enhanced rain or snow that falls downwind from the lake.
LAKE EFFECT SNOW

LIGHTNING: All of the various forms of electrical discharge produced by thunderstorms.
Lake Effect Snow - Localized snow that forms on the downwind side of large lakes. It's common in the late fall and winter in the Great Lakes region when cold, dry air picks up moisture from the unfrozen lake surfaces.
of the atmosphere. Generally, values greater than about 18 indicate sufficient instability for severe thunderstorm development. 2) The difference in temperature between the surface of a lake and 850mb, typically used to determine lake effect snow ...
A way of determining whether lake effect snow showers are likely to develop over the Great Lakes. Typically, this is done by taking the absolute value of the difference in temperature between the 850 mb temperature and the lake water temperature.

Also, it is the name given to the length of the fetch area, measured in the direction of the wind from which the seas are generated. One of the ingredients for lake effect snow is the fetch of the water over which cold air can gain moisture.
Some previous COMET projects have produced better methods of forecasting windstorms, marine weather for the Great Lakes, lake effect snow storms, and flash floods.
