After the first 4 days this month, Chicago’s veteran weather observer, Frank Wachowski had measured 84% of possible sunshine, including 98% on the 1st and 100% on the 3rd and 4th, but conditions then took a turn toward predominant cloudiness, including the last three days and 5 days out of the past six with 0% sunshine. As of December 11th, we now stand at 36% of possible sunlight – normal for December is 40%.
