Great Lakes six degrees colder then normal

Water temperature of the Great Lakes is over 6 degrees colder than normal

Meteorologist Mark Torregrossa writes on Michigan Live about the lingering effect of historic ice extent last winter in the Great Lakes and late ice melt this summer due to that extent:
Lakes Superior and Lake Michigan are currently six degrees colder than last year. If the water continues to remain colder than normal, it could have an impact on Michigan’s winter in several ways.
The average water temperature on Lake Superior and Lake Michigan is currently colder than both last year and the long-term average.
Currently Lake Superior has an average surface water temperature of 47.6 degrees. Last year on this date Lake Superior was at 53.7 degrees. The long-term average water temperature on Lake Superior for October 11 is 51.1 degrees.
So Lake Superior is 6.1 degrees colder than this time last year, and 3.5 degrees colder than normal.
Lake Michigan has an average surface water temperature of 56.0 degrees, while last year at this time it was 62.1 degrees. The long-term average water temperature on Lake Michigan for October 11 is 58.4 degrees.
Lake Michigan is also 6.1 degrees colder than this time last year, and 2.4 degrees colder than average.
Lake Huron is 5 degrees colder than last year, and only 1.5 degrees colder than normal.
