The History Channel has an excellent retrospective on the D-Day invasion of Normandy, France, which occurred on June 6, 1944.  The weather forecast for that event was crucial in making it a success.  You might enjoy reading about it and watching some video at https://www.history.com/news/the-weather-forecast-that-saved-d-day.  USA Today also had a feature about this in 2014 which included the weather maps for that date at https://www.usatoday.com/story/weather/2014/06/03/d-day-weather-forecast/9914207/.  Mashable.com also has a different version of the map, which they called “the most important weather map in history,” at https://mashable.com/2014/06/06/most-important-weather-map-in-history/#RhWlY6sW3SqF.
