1948 – The first successful tornado forecast predicts that a tornado will strike Tinker Air Force Base, Oklahoma.

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. The March 20 tornado was the costliest tornado in Oklahoma history at the time.
Tinker’s meteorologists Major Ernest J. Fawbush and Captain Robert C. Miller investigated surface and upper-air weather data from this and past tornado outbreaks, hoping to be able to identify conditions which were favorable for tornadoes. By March 24, they had compiled several possible tornado indicators, and decided it would be difficult, but possible, to identify large tornado threat areas in the future.
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. Equipment which could be, had been moved to bomb-proof shelters, and base personnel had been moved to safer areas.This was the first official tornado forecast, as well as the first successful tornado forecast, in recorded history. Due to lives and costs saved, Fawbush and Miller continued their tornado forecasts, which verified at quite a high rate over the next three years. At first, they kept their forecasts secret. In the spring and summer of 1949, they issued eighteen forecasts for tornadoes within a 100-square-mile (260 km2) area, and all eighteen proved successful. In the subsequent years, while not explicitly using the word “tornado”, the Weather Bureau used the pair’s forecasts to predict “severe local storms”.
The synoptic pattern which occurred on March 25 later became known as the “Miller type-B” pattern and is recognized as one of the most potent severe weather setups.
