Quite a few people have been asking for lake effect snow. Well, they're not actually asking for lake effect snow. They're asking me to explain lake effect snow for the weather word of the week.

I'm Storm Shield Meteorologist Jason Meyers, and lake effect snow is enhanced snowfall caused by cooler air blowing over a relatively warmer lake.

All of the snowiest cities around the world receive as much snow as they do because of their proximity to a lake or ocean, which enhances snowfall in the winter.

In the United States, these are cities surrounding any of the Great Lakes, but especially Lake Ontario, Lake Erie, and Lake Michigan.

Lake effect snow is most common in the Fall. That's because land cools down much faster than water.

The warmer, moist air over the lake rises to form clouds. If cold winds through the lower levels of the atmosphere blow in a similar direction, this causes snow to form and move over the land.

With the right amount of instability and proper wind field, strong lake effect snow bands can result in multiple inches of snow per hour, lasting for hours at a time, and burying cities in the process.

But once the lake freezes over, lake effect snow comes to an end.
