Weather History for March 25
 
1934
A spring storm produced 21 inches of snow at Amarillo TX in 24 hours. However, much of the snow melted as it fell, and as a result, the snow cover was never any deeper than 4.5 inches. (David Ludlum)

1948
For the second time in less than a week airplanes were destroyed by a tornado at Tinker AFB in Oklahoma City OK. A March 20th tornado destroyed fifty planes at Tinker AFB causing more than ten million dollars damage, and the March 25th tornado destroyed another thirty-five planes causing six million dollars damage. The first tornado struck without warning, and caused more damage than any previous tornado in the state of Oklahoma. The second tornado was predicted by Fawbush and Miller of the United States Air Force, and their accurate tornado forecast ushered in the modern era of severe weather forecasting.
