The 557th Weather Wing traces its heritage back to a meteorological service unit in the Army Signal Corps during World War I with its operations in France. Its official lineage began in 1943 with the activation of the Army Air Forces Weather Wing in Asheville, North Carolina. Since 1991, the unit has reported directly to the Air Force Director of Weather at the Pentagon, when it was known as the Air Weather Service, located at Scott AFB. In 1997, AWS was re-designated as AFWA, which also merged the mission of Air Force Global Weather Center at Offutt AFB.
On March 27, 2015, the Air Force Weather Agency was officially re-designated as the 557th Weather Wing. As such, the 557th WW stands alone as the Air Force’s premier weather wing, providing world-class weather support and decision superiority to commanders and warfighters to “win today's and tomorrow's fight."
The re-designated unit's new emblem borrowed from AFWA's, but with one noticeable change. The verbiage at the bottom now reads, "Coelum Ad Prelium Elige," which is Latin for, "Choose the Weather for Battle."
