Today is a special anniversary in the annals of weather forecasting. As noted in a previous column, it was this date in 1948 that two U.S. Air Force weathermen, Capt. Robert Miller and Maj. Ernest Fawbush, proved with a certain degree of accuracy that a prediction could be issued determining when a tornado would hit. With reams of atmospheric data and a radarscope designed for a World War II airplane, the two officers issued the first tornado warning. They determined atmospheric conditions were identical to an earlier tornado that damaged the base and predicted the next would be stronger than the first. Miller and Fawbush typed out a warning; people were evacuated, controllers and airplanes were tied down. The results and consequences in Tuesday’s column.

Fastcast: Unseasonably cool.
