The station is known for its series of civic and consumer watchdog reports during its evening newscasts called "The Turko Files", helmed by investigative reporter Michael Turko (who regularly utters the line "It Ain't Right" during the segments). From 1994 to 2014, John Coleman (a longtime Chicago weatherman and co-founder of The Weather Channel) served as KUSI's chief meteorologist, appearing on its evening newscasts. During his tenure at the station, Coleman was known for his trademark drawn-out pronunciation of the station's call letters ("K-uuuuuuuuuuu-S-I"), and providing his own lively presentation during the forecast segments (often referring to the strong winds that affect the area as the "SOSA" (or "Sort of Santa Ana"), and breaking out in dance at random). Coleman retired from broadcasting in April 2014 after a 61-year career; however, he did not appear on-air for a proper sendoff (as he was on vacation at the time) when KUSI ran a retrospective of his career on the April 10 edition of the 6:00 p.m. newscast.
