in the United States to introduce a model-based computer forecasting system with the introduction of "MAX", which compiled model data to display hour-by-hour forecasts up to 48 hours in advance. On June 13 of that year, during coverage of a supercell thunderstorm that spawned seven tornadoes across Canadian and northern Oklahoma counties, a camera atop the station's transmission tower caught the collapse of a nearby auxiliary tower operated by KFOR-TV and radio station WKY (930 AM) from intense downdraft winds. In 2000, the station introduced "I-News", internet-enabled software for personal computers that provides severe weather and breaking news alerts to users. KWTV debuted "MOAR" (for "Massive Output Arrayed Radar"; though colloquially referred by England as the "Mother of All Radars") on May 8, 2003, to track an F4 tornado that hit Moore; the radar used enhanced street-level mapping to detect the path of tornadoes and GPS to track the location of KWTV's storm spotters. In February 2007, KWTV debuted "Storm Monitor" (later known by its brand name of ESP for "Early Storm Protection"), which utilized VIPIR technology to measure a mesocyclone's strength and its tornado-producing potential. David Payne, who joined KWTV in February 2013 after a 20-year tenure as a morning meteorologist and storm chaser at KFOR, subsequently took over as chief meteorologist on August 29 of that year. In April 2015, KWTV restructured the extended forecast graphic seen at the end of its weather segments from a seven-day to a nine-day forecast, both in reference to the station's virtual channel number and to take advantage of the 16:9 frame (likewise, rival KOCO-TV subsequently altered its extended forecast to a ten-day outlook, known as the "5+5 Day Forecast", in reference to its virtual channel). On December 2, 2016, KWTV unveiled "NextGen Live", a dual-polarization Doppler weather radar designed by Baron Services, which conducts atmospheric scans at 6 RPM—a faster rate than the radars operated by its three main competitors, KFOR, KOCO (which both have their own on-site radars) and KOKH (which has a radar system that relays NEXRAD imagery from the National Weather Service)—to detect precipitation in real-time; the system operates at one million watts of power, and scans at both X & Y axis (the system is similar to KFOR-TV's dual-pol radar that operates at the same power and predates "NextGen Live" by ten years).
