Researchers have found that summer air temperatures over Lake Superior have been increasing more than a degree per decade, bringing changes in weather patterns for the surrounding regions

If you live close to one of the Great Lakes and think that average summer winds in your area have changed in recent decades, you may be right.
Several years ago, researchers at the Milwaukee campus of the University of Wisconsin noted that there had been a significant shift in summer wind directions over the Great Lakes since 1980, dominated by an increase in air flow from the south. They suggested that a change in the dominant track for summer storms was a primary reason for this change.
