Lake-effect snow occurs when cold air crosses the relatively warm waters of the Great Lakes. Cities like Marquette, Erie and Syracuse get as much as 70% of their seasonal snow from these localized snowstorms.
Where is lake effect snow most common?
Lake effect snow is common across the Great Lakes region during the late fall and winter. Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes.
What states get lake effect snow?
In the U.S. lake effect snow commonly occurs across northern Wisconsin, western Michigan, northwestern New York, northwestern Pennsylvania and the Great Salt Lake in Utah.
What are two areas that are affected by lake effect snow?
Three geographic regions commonly affected by lake effect snow are the Great Lakes, the east shore of Hudson Bay , and the west coasts of the Japanese islands of Honshu and Hokkaido.
Does Chicago get lake effect snow?
Chicago does get some lake-effect snow when winds blow in from the northeast , but typically the area receives lake-enhanced snowstorm totals from the organized northeast winds that accompany snow-producing low-pressure systems passing south of the city. ...
Why is lake-effect snow so bad?
The Physics of Lake-Effect Snow
Cool air cannot hold as much moisture as warm air . If there is enough moisture, some of it condenses and falls as snow or rain.
Does lake-effect snow stop when lake is frozen?
Luckily for people living near large lakes, lake-effect snow generally slows down around February . That’s when the lakes freeze over, making it impossible for the air to steal moisture away from the lake.

What is the difference between snow and lake-effect snow?
There are two main differences between lake effect snowstorms and winter (low pressure) snowstorms: (1) LES are not caused by low-pressure systems, and (2) they’re localized snow events . As a cold, dry air mass moves over the Great Lakes regions, the air picks up lots of moisture from the Great Lakes.
Can you predict lake-effect snow?
The HRRR is NOAA’s hourly updating, short-term weather model, and is the most commonly used weather model for predicting lake-effect snow. But the HRRR needs accurate water surface temperatures to properly estimate evaporation rates from lake surfaces, which is the main driver of lake-effect snow.
Does lake effect snow show on radar?
Weather radar starts out as a signal transmitted from the radar dome near the ground. ... The low nature of lake effect snow means the weather radar beam can shoot right over the top of the lake effect snow and not “see it.” That is why you will often look out the window in the U.P. of Michigan and it is snowing hard.
How do you stay safe in lake effect snow?
- Stay indoors and dress warmly.

- Watch for signs of hypothermia and frostbite.
- Keep dry. ...
- If you must drive, carry a cell phone.
- Keep the gas tank full.
Which side of large lakes receives greater amounts of snowfall?
Lake-effect snow typically forms on the downward side of a lake. Lake Erie and Lake Ontario are positioned in such a way that prevailing winds from the west blow the entire length of the lakes often generating huge amounts of snow that fall on the east end (downwind side) of the lakes and surrounding land.
Why Chicago is so cold?
Although the city is located at a middle latitude, in winter it is cold because the North American land mass cools down a lot, and polar air outbreaks are frequent . ... Winter in Chicago runs from late November to early March and is cold, to the point that the average temperature is reminiscent of Northern European cities.
Is Chicago colder than London?
London’s weather is greatly influenced by the Gulf Stream, a warm ocean current with origins in the Caribbean. ... London shares a similar latitude (51.5 degrees N) with cities like Warsaw, Kiev, and Winnipeg and is nearly 10 degrees north of Chicago .
