D-Day was originally scheduled for June 5, 1944 but poor weather predictions influenced General Dwight D. Eisenhower to delay the invasion. Eisenhower’s chief meteorologist, British Capt. James Stagg stood alone in his assessment of impending rough seas and high winds for the English Channel against the predictions of his colleagues. The improved weather on June 6, while not ideal, is often cited in the overall success of Operation Overlord.
