DISCUSSION: As we look back to June 6th, 1944, the world arrives at a truly historic day in weather history. Attached below is a neat conversation courtesy of the Met Office which provides insights into how the forecast leading up to D-Day evolved and how it impacted the way in which D-Day evolved.
"In 1944, critical decisions were made based on weather forecasts compiled using data gathered from air reconnaissance, ship observations (often sent ashore using pigeons), UK observation sites and from the Germans - once the allies broke the Enigma code. All observation sites were manned, as opposed to automated as they are today, and charts were hand drawn every few hours.
The German weather charts were drawn using much fewer observations. National Meteorological Archive Catherine Ross said: "The Allied charts contain a wealth of observations from across the UK and Europe, by contrast the German charts reveal that they had been unable to crack the Allied codes and as a result there are virtually no observations for the UK and surrounding waters. The difference in the information available to both sides gave the allies a crucial advantage on D-Day."
Group Captain James Stagg, RAF and Chief Meteorological Officer at Supreme Headquarters Allied Expeditionary Force, led a team of meteorologists charged with providing forecasts to the Allied Commanders deciding when to launch the D-Day offensives. They considered all the elements that would impact operations and drew up a wish list of ideal conditions for the D-Day landings."
