Since DFW has been covered, I'll add San Antonio's Fox affiliate KABB, which airs a morning newscast from 5am-9am followed by "Daytime at 9" (a lifestyle newscast). No other newscasts follow throughout the day until a 9pm newscast later that night (mostly due to sister NBC station WOAI which prevents KABB doing a noon, 4pm, 5pm, 6pm, and 10pm newscast). In addition, the other sister station KMYS, a CW station, had aired KABB's 9pm newscast during the World Series, Super Bowl, etc. but I don't know if they do that anymore.
I do know that some Fox affiliates that air a 4pm newscast (i.e KPTV, etc.) Any others?
