News Source" concept (which was enforced in the promotional slogan used by the station until 1999, "Kansas City's 24-Hour Newschannel"). Its iteration of the concept involved both the production of 30-second news updates that aired at or near the top of each hour during local commercial break inserts – even during prime time network and overnight programming – and five-second end-of-break weather updates (consisting of an image of the station's Doppler radar, then known as "Doppler 4 Radar", usually accompanied by a brief voiceover by one of the station's meteorologists illustrating the short-term forecast or teasing the weather segment in an upcoming newscast), during time periods when the station was not airing its regularly scheduled, long-form newscasts. In September 1992, WDAF became the first television station in Kansas City to launch a weekend morning newscast, with the debut of two-hour-long Saturday and Sunday broadcasts that initially aired from 8:00 to 10:00 a.m. (both editions would later move to 7:00 to 9:00 a.m. in September 1997, with the Saturday edition moving one hour earlier on April 23, 2016). After WDAF became a Fox affiliate on September 12, 1994, the station underwent a major shift in its programming philosophy that more heavily emphasized its local news programming.

In its early years with Fox, local news programming on the station ran on weekdays from 6:00 to 9:00 a.m., 12:00 to 1:00 p.m. and 5:00 to 6:30 p.m. and nightly from 9:00 to 10:30 p.m., as well as on weekend mornings and early evenings. The station retained the "24-Hour News Source" format after the affiliation switch, continuing to offer news updates on an hourly basis during commercial breaks until it discontinued the concept in May 1999. With New World Communications heavily investing in the news department's expansion, WDAF increased its news staff from 80 to 120 employees; it hired up to 40 additional employees (including additional reporters and behind-the-scenes staff members) to handle the expanded news coverage that the new news-intensive lineup would allow.
