During the afternoon and evening of April 10, 1979, about 15 years after the City View twister, KFDX-TV provided complete coverage of an outbreak of tornadic thunderstorms that spawned several strong to violent tornadoes across northwest Texas and southwestern Oklahoma. That evening's coverage culminated with the opening segment of the 6:00 p.m. edition of "Newscenter 3", as chief meteorologist Bill Warren was relaying reports of a multiple-vortex tornado that was beginning its path of destruction across southern sections of Wichita Falls. Four minutes into the newscast, electricity to the KFDX studio and transmitter facilities went down as the storm knocked sections of the city's electrical grid offline. (KAUZ, KSWO and five of the six radio stations operating in the Wichita Falls area at the time also lost power in the storm, although local radio station KTRN now KWFS-FM was able to remain on-air as it had an auxiliary power supply). Along its , path, the F4 tornado killed 42 and injured more than 1,700 people, and produced damage estimated at around $400 million; among the 20,000 residents estimated to have been left homeless because of the twister, sixteen of them were part of KFDX-TV's 39-person staff at the time. When the station came back on the air at 6:56 p.m. the following evening (April 11), KFDX provided 3½ hours of continuous live coverage of the aftermath of the tornado. One week later, Channel 3 broadcast a half-hour documentary about the 1979 tornado, "Terrible Tuesday", chronicling the Wichita Falls tornado and its aftermath by way of news footage taken by the station after the storm.
