Lake effect precipitation forms when there is a large enough temperature difference between the Great Lakes surface water temperatures and air about 5,000 feet up. One condition that lends itself.. For lake-effect rain or snow to form, the air moving across the lake must be significantly cooler than the surface air (which is likely to be near the temperature of the water surface) Lake effect can produce everything from light rain to heavy snow to thundersnow that combines a thunderstorm with heavy snowfall. Depending on the conditions, lake effect can be the sole contributor to severe blizzards in lake regions
With lake effect snow in the forecast today across the Great Lakes, it's a perfect time to discuss what lake effect snow is, how it forms, and how to predict/track it with the tools at weather.us.

rain shadow effect 2. lake effect snow- 5 Great Lakes near Canada; cold air moves over a large warm lake; as the cold air crosses the lake it picks up moisture through evaporation; moist air rises into cold air; forms enormous amounts of snow in a short amount of time; size of the lake, temperature, and slope determines the amount of sno In the U.S., lake-effect snow most commonly forms downwind of the Great Lakes. Many other lakes and bodies of water manufacture bands of snow and rain from this mechanism The climate around Lake Superior is colder than that around other Great Lakes, which makes it more able to support snowfall for a longer period of time, even when temperatures warm. Eventually, though, as temperatures continue to rise, lake effect snows turn into rain
. These rain showers behave like lake effect snow bands.. Cooler, moist air may form clouds and cause precipitation. After the air has moved some distance over the lake, convection and turbulent exchange have transported the moisture aloft to form clouds
. In order for lake effect rain or snow to form the temperature difference between the water temperature between the surface and 850 mb should be at least 13 degrees Celsius. Lake effect of extremely.. A notable characteristic of Fig. 6 is the relatively quick transition from lake-effect rain to lake-effect snow days.

Lake-effect snow is caused when cold Arctic air sweeps over the open water of a big lake and picks up some of its moisture. It hangs onto that moisture until it hits dry land. Then all that moisture lets go and falls as narrow streamers of snow, a lot of snow . The lake effect takes over on Thursday, leading to scattered snow showers and squalls during..
Lake effect snow (LES) is a local weather event that occurs when a cold air mass passes across an expanse of warm water creating convective snow bands. The phrase lake effect refers to a body of water's role in providing moisture to air that would otherwise be too dry to support snowfall Lake Effect Snow Can Be Dangerous. Lake effect snow storms can be very dangerous. For example, 13 people were killed by a storm that took place November 17-19, 2014 in Buffalo, New York. During the storm, more than five feet of snow fell over areas just east of Buffalo, with mere inches falling just a few miles away to the north Wind plays a big role in which lake the lake band comes from, how strong the lake band can be, and the general placement of where the band will set up.. MORE⼁Lake-effect snow defined: How 'the snow machine' works A typical rule of thumb and a common way we describe the direction that lake effect snow will come from is using degrees as on a compass, where north is 360 degrees, east is 90.

There are three necessary conditions for lake effect, said Kirk Apffel, a meteorologist with the weather service in Buffalo: cold air, the right wind direction, and moisture in the atmosphere Lake Effect Snow is a type of snow event we commonly see across the Great Lakes region during the Fall and Winter months. But for it to happen, we need the lakes to be unfrozen and a difference in temperature between the relatively warmer lake water and the colder air
Rain showers develop this evening and change to some lake effect snow showers after midnight. Not much if any accumulation is expected. Another messy storm system is on the horizon for New Years. The temperature lapse rate between the warmer lake surface and the colder air at around 5,000 feet will become sufficient for a lake response producing true lake-effect rain. The uncertainty lies..
As with tropical storms, the energy for the formation of lake effect snow is derived from atmospheric instability and warm water.
