"Weather for The Big One"
The invasion of Europe on June 6, 1944 was the greatest military operation in history. As noted in a previous column, if the weather was unfavorable for Operation Overlord, it would have postponed the invasion for two weeks until tides were suitable for landing. Weatherwise Magazine reports that in 1944, there were no meteorological observations or the use of computer models. Years ago, predicting the weather over the English Channel was challenging. Weathermen depended on secretive ship and plane reports and from spies on the European mainland. These observations were coded, forwarded to England and tediously plotted to maps by hand. Numerous groups extrapolated the data including: a civilian group in Dunstable, England, The British Meteorological Service, U.S forecasters called Widewing and the British Navy.
