The 1948 Tinker Air Force Base tornadoes were two tornadoes which struck Tinker Air Force Base in Oklahoma City, Oklahoma, on March 20 and 25, 1948. Both are estimated to have been equivalent to F3 in intensity on the modern Fujita scale of tornado intensity, which was not devised until 1971. The March 20 tornado was the costliest tornado in Oklahoma history at the time. On March 25, meteorologists at the base noticed the extreme similarity between the weather conditions of that day and March 20, and later in the day issued a "tornado forecast", which was verified when a tornado struck the base that evening. This was the first official tornado forecast, as well as the first successful tornado forecast, in recorded history.

- La première prévision réussie de tornade date du 25 mars 1948. En l’espace de cinq jours, la base aérienne de Tinker, juste à l’est d’Oklahoma City aux États-Unis, fut frappée par deux tornades, un fait extrêmement rare. La première de celles-ci fit 10 millions USD de dégâts, la somme totale la plus élevée à cette date en Oklahoma. L’étude des conditions ayant conduit à cette tornade a permis aux officiers météo Ernest J. Fawbush et Robert C. Miller de mettre en pratique des études récentes sur le sujet et d’émettre un avertissement de tornade le 25 mars, quelques heures avant l’arrivée d’une seconde tornade à 18 h locales. (fr)

Ce succès, ajouté au soutien moral du commandant de la base, poussa les deux militaires à poursuivre leurs prévisions dans ce domaine, ce qui eut des répercussions importantes sur la prévision des orages violents aux États-Unis et dans le monde.
