This phrase describes a specific atmospheric transition documented within a Terminal Aerodrome Forecast (TAF) originating from Oklahoma City’s Will Rogers World Airport (KOKC). It signifies a shift from ostensibly cloudless conditions to the development of visible cloud cover. A TAF utilizes specific meteorological codes to concisely represent anticipated weather phenomena at an airport. This particular transition indicates an alteration in the prevailing sky condition.
The importance of this information lies in its impact on aviation operations. Pilots rely on TAFs for pre-flight planning, particularly concerning visibility and ceiling height, both critical factors for safe takeoffs and landings. The shift from clear skies to cloud cover can influence flight paths, approach procedures, and potentially necessitate diversions to alternative airports. Historically, accurate weather forecasting, including the prediction of such transitions, has significantly improved aviation safety by providing pilots with the information needed to make informed decisions.
