The Weather Forecast That Changed History

The weather forecast for one of the most memorable days in American history proved to be a difficult and vital one.  WWII.  D-Day.  Originally scheduled for June 5th, 1944, D-Day would be the time Allied forces would launch an offensive invasion on the beaches of France in hopes of loosening the grip that the Nazi regime had on Europe.

With high winds and heavy rain in the forecast on the 5th, Allied military leaders teamed up with a team of meteorologists to make a huge decision that would change the course of history.  Ultimately, D-Dday, in the wake of bad weather, was moved to June 6th, 1944.  The meteorologists were spot on.
