KTLX is a NEXRAD WSR-88D weather radar southeast of Oklahoma City, about 17 km from Midwest City and 19 km from Norman and Moore, at a site NCEI also lists under the name Twin Lakes. The NWS radar list names it Oklahoma City, OK, while the NWS API and the Radar Operations Center call the system Norman, after the Norman forecast office that runs it. That office is also the responsible office for the Department of Defense radars at Frederick (KFDR) and Vance Air Force Base (KVNX).
Norman is home to the Radar Operations Center, which supports every WSR-88D, and the ROC's history places this radar at the network's beginning: the first limited production unit was delivered to Oklahoma City in May 1990, and Norman was one of the first three field sites using the system when the WSR-88D hotline opened in November 1991. In February 2020 KTLX was the first radar to have a new generator installed under the Service Life Extension Program, returning to service after seven days. Wikipedia's list of NEXRAD sites gives June 1991 as the start of its data record.
Radar shows rain, snow and hail, not cloud, and nothing below its lowest beam; far from the antenna the beam passes high above the ground.
