Lake Superior Reaches Record Temp. By Bob Kelleher, Minnesota Public Radio, August 12, 2010. "On August 10 the waters atop Lake Superior reached the highest temperature ever recorded. The lake-wide average surface temperature hit 68.3 degrees. The average for Aug. 10 is just 55 degrees. The keeper of those records is Jay Austin, an associate professor of physics at the University of Minnesota Duluth's Large Lakes Observatory. He's observed record warmth in both lakes Superior and Michigan, with Huron and Erie both quite warm as well… Researchers say the trend for several decades now is clear -- ice is forming later on Superior, going out earlier, and like this year, allowing the lake to warm earlier and longer."
