Overview
Yesterday marked the 59th anniversary of the assassination of President John F. Kennedy and the weather played a crucial role. The day started off with some rain in Dallas, Texas on November 22nd, 1963 and the forecast was for more rain later in the day. If the forecast had turned out to be correct with more rain on that fateful day then that would have likely meant that a plexiglass bubble top would have been used on President Kennedy’s 1961 Lincoln Convertible on a planned motorcade through the Dallas metro region. But the weather cleared unexpectedly, the protective top was removed from the car, and shots rang out in the early afternoon hours at Dealey Plaza killing the 35th President and seriously wounding Texas Governor John Connally.

Details
The day started out damp and overcast in Dallas on November 22nd, 1963 with 0.06 inches of rain as a cool front was working its way through northern Texas. The local weather forecast had called for more rain later in the day, but it turned sunny and bright in the late morning hours just as President Kennedy’s motorcade was set to leave for the cross-town journey in Dallas. The unexpected sunshine combined with stiff southerly winds of 15-30 mph helped to boost temperatures rather quickly towards an afternoon high near the 70 degree mark.

As a result of the unexpected turn of events with the weather, President Kennedy opted to not go with the plexiglass bubble top on the 1961 Lincoln Convertible despite the wishes of the Secret Service. Crowds were already lining the streets in Dallas and President Kennedy wanted them to be able to see him during the ride which was expected to last less than an hour. The motorcade drove through most of the planned route and was about to turn onto a road which would allow it to speed up, but first it had to slow down as it turned to go through Dealey Plaza around 12:30 pm. Shortly after slowing down for the turn into Dealey Plaza, shots rang out killing the 35th President and seriously injuring Texas Governor John Connally. Had the weather remained cloudy with light rain as predicted, the assassination of President Kennedy may not have taken place on that fateful day.
