with an accuracy of up to ). Two weeks after the radar was installed, on May 22 (shortly before it was shut down briefly due to the expiration of the radar's temporary operational license), it detected a tornado near Arapaho; that tornado—which was recorded by a photographer inside "Ranger 9," which briefly was caught in the parent thunderstorm's inflow winds—became the first ever to have been filmed by a news helicopter. The first broadcaster-issued tornado warning indicated by Doppler occurred using this radar for a tornado that hit Ada on March 15, 1982; the ability to issue warnings ahead of the National Weather Service led to frequent disputes over jurisdiction in the issuance of severe weather alerts between the agency's Norman office and channel 9 into the early 1990s. From 1982 to 2006, England and the KWTV weather staff presented "Those Terrible Twisters" (titled "Gary's Traveling Weather Show" until 1986), a weather education tour around Oklahoma communities during the spring and summer that taught tornado safety information and promoted the station's severe weather forecasting efforts; the station also produced half-hour specials under that banner each spring, showcasing footage shot by KWTV storm spotters and behind-the-scenes video of its storm coverage. In 1990, England, with the help of a station technician, co-developed First Warning, a software product that displays a weather alert map (which was originally updated via manual input by weather staff) during regular programming, along with a crawl showing detailed alerts issued by the NWS and the National Severe Storms Forecast Center. ("First Alert", an automated iteration of the software, was developed by KOCO that same year.) In 1991, England convinced station management to hire a software development firm to create an application, which would be dubbed "Storm Tracker", an automated computer tracking system that projected the arrival time of precipitation at a particular locale. That year also saw the hiring of Val Castor, a studio camera operator who would eventually become the station's first in-house storm spotter; KWTV gradually expanded its spotter units, employing twelve teams by 1999. In 1992, the station introduced "Storm Action Video", a system (developed by then-evening anchor Roger Cooper) that sent near real-time video over cell phone transmissions using a MacIntosh computer combined with video compression codecs; a similar system that transmitted real-time cell phone video, using Colby Electronics equipment, was developed in 1993. In 1998, KWTV became one of the first stations
