Lake Effect Snow

Yesterday the lake effect snow machine turned back on.  We received a few inches of snow.  Tonight system snow is moving our way.  In the eastern U.P. we are expecting 4-6 more inches.

Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water, warming the lower layer of air which picks up water vapor from the lake, rises up through the colder air above, freezes and is deposited on the downwind shores.  The difference in temperature must be over 20 degrees F.
