Action transferred overseas weather units to the command of the new service. On 7 January 1946, the service moved to Langley Field, Virginia. In early 1946, the AAF determined to place its technical services under the command of Air Transport Command. On 13 March 1946, AAF Weather Service was redesignated Air Weather Service and along with Air Communications Service, Air Rescue Service. and Air Pictorial Service, assigned to Air Transport Command Soon afterwards it moved to Gravelly Point, Virginia, where it was colocated with ATC headquarters. Weather reconnaissance During the war, the AAF had developed weather reconnaissance units for scouting and route weather observation and reporting, but these units had remained under the command of theater commanders or Air Transport Command. Once Air Weather Service became part of ATC, the time was ripe to place a weather reconnaissance unit under its command. In July 1946, it established the Air Weather Group (Provisional) at Morrison Field, Florida. In October, this group was taken out of provisional status and became the 308th Reconnaissance Group, Weather. Expansion worldwide With the formation of the United States Air Force in 1947, Air Weather Service assumed the responsibility of worldwide weather reporting and forecasting for both the Air Force and the Army. In 1948, Air Weather Service moved to Andrews Air Force Base, Maryland, and was assigned to the newly activated Military Air Transport Service, which was later redesignated Military Airlift Command. Air Weather Service moved to Scott Air Force Base, Illinois, in 1958, where it remained for nearly four decades. Transfer of weather functions to the operational commands Air Force Weather, organized as the Air Weather Service from 1947 to 1993, continued to provide environmental awareness for both the Air Force and the Army. By 1991, Air Weather Service had divested itself of its major field structure and the bulk of Air Force Weather was realigned under the direct administration of the supported commands. Air Force Weather Agency and its predecessors have been essentially instrumental in protecting life and property at home as well. Since World War II, Air Force weather personnel have provided hurricane reconnaissance. In 1948, two Air Force weather officers issued the first tornado warning. Air Force Weather participated in the nation's development's severe storm forecasting centers. With its early adoption of emerging computing and communications technologies, Air Force Weather was at the fore of the Space Age. In the 1960s, Air
