Answer 1

Lake Superior the coldest lake of the Great Lakes.

It is due to Lake-effect snow.

Lake-effect snow is produced in the winter when cold, Arctic winds move across long expanses of warmer lake water, providing energy and picking up water vapor which freezes and is deposited on the lee shores. The same effect over bodies of salt water is called ocean effect snow, sea effect snow, or even bay effect snow. The effect is enhanced when the moving air mass is uplifted by the orographic effect of higher elevations on the downwind shores. This uplifting can produce narrow, but very intense bands of precipitation, which deposit at a rate of many inches of snow each hour and often bringing copious snowfall totals. The areas affected by lake-effect snow are called snowbelts. This effect occurs in many locations throughout the world, but is best known in the populated areas of the Great Lakes of North America.

Answer 2

Lake Superior has the most water in it, it is the deepest lake, it has the highest elevation, and it is the farthest north.  For all of these reasons, it is the coldest of the Great Lakes.
