I am not certain if South Louisiana has ever experienced a weather situation familiar to northern extremes.  Traditionally our first freeze is near the beginning of winter constituting. Back to the northern extremes when Indian summer occurs in mid to late autumn, usually after the first killing frost.  As noted, it’s extremely rare to experience this weather scenario in our sub-tropical climate but is greatly appreciated through other sections of the country.  Its usage has been traced to 1778 as Native Americans utilized these days to increase their winter food stores.  In Europe a similar weather pattern has been called Old Wives’ summer, Halcyon days, and St. Martin’s summer. Years ago, I referenced Indian summer on one of our broadcasts and received an e-mail from Marsha Reichle.  She wrote, “Dear Pat:  It’s called Indian summer when we have Apache fog.”
