The year 1927 brought the worst floods in US history, and the worst floods in Vermont history. It also brought the hottest September 15 on record in the US.
September 15 temperatures have plummeted in the US over the past 90 years.
On September 15, 1927 almost the entire eastern half of the US was over 90F, with Pennsylvania, Indiana, Illinois, Iowa, Kentucky, Tennessee Virginia, and most of the rest of the south all over 100F. Temperatures this hot in mid-September are incomprehensible now.
