The Weather on D-Day
Perhaps the most important weather forecast ever made was the one for D-day, the Allied invasion of France. It succeeded not because of the brilliant work of any solitary forecaster, but because a group of forecasters imitated the weather. They jostled, yelled, scribbled, and cast malevolent looks at one another. They fought it out and voted. And in the end, they were just right enough.
The invasion of France had been scheduled for June 5, 1944. To bring off the invasion, General Dwight D. Eisenhower needed a full moon, a low tide, little cloud cover, light winds, and low seas. (The low tide was necessary to allow soldiers to see, avoid, and disarm the mined obstacles that the Germans had placed in the surf.) He could have had the full moon and low tide on June 5, 6, or 7. He could have had the low tide without the full moon on June 19 or 20. But what about the weather?
