Illinois Weather Trivia for July 20th

7/20/2010
An average summer in central Illinois usually sees one or two days with high temperatures of 100 degrees or higher. An analysis of Springfield weather records, which began in 1879, indicate that the longest period between 100 degree highs is 15 years and counting, with no 100 degree days occurring since July 1995. The next highest total is 11 years, from July of 1890 to July of 1901. And after that, the next 100 degree high occurred in June of 1911, nearly 10 years later.
