Anyone who lives in Milwaukee or has driven on the elevated freeway loop south of Downtown knows the Wisconsin Gas Building, a beautiful Art Deco tower topped by a weather beacon in the shape of a flame.  The flame changes color to announce the weather forecast.

• When the flame is red, there’s warm weather ahead!
• When the flame is gold, watch out for cold!
• When the flame is blue, there’s no change in view!
• When there’s a flickering flame, expect snow or rain!

On my way back from getting coffee I happened to notice the Gas Building flame glowing in the sunlight (at center left, below, through the trees).  I believe that must be an extreme shade of gold, to signify even COLDER cold!
